Development of the Test de Phrases dans le Bruit (TPB) laboration du Test de phrases dans le bruit (TPB)
Jose Lagac Benot Jutras Christian Gigure Jean-Pierre Gagn

Abstract

The Test de Phrases dans le Bruit, which consists of ve French lists of 40 recorded sentences and a speech babble, was developed for use in evaluating speech perception in noise. The development of the sentence material was based on an approach that had previously been employed for the Speech Perception In Noise test. The key word familiarity of the sentences was tested, as well as the intelligibility in noise. Measures were also performed to obtain equivalent difference of scores between the high and low predictability sentences across the lists. Based on the results obtained with a subset of adult participants, it is believed that the sentence list sets that evolved from this work have the characteristics to be useful for the exploration of the underlying auditory and/or language-based origins of speech perception problems in noise among the Canadian French population. However, the present ndings should be interpreted with caution as only individuals with normal hearing function participated in the experiments. The results may not apply to individuals with speech perception problems in noise. Additional evaluations of the psychometric properties of the test must be performed before its clinical application. Nevertheless, these preliminary ndings suggest that further development of the Test de Phrases dans le Bruit is warranted.

Le Test de phrases dans le bruit, qui est compos de cinq listes de quarante phrases enregistres en franais et dun bruit de verbiage, a t conu pour valuer la perception de la parole dans le bruit. Llaboration des phrases a t effectue en suivant une approche similaire celle du Speech Perception in Noise (SPIN). La familiarit du mot cl de chaque phrase a t vrie, ainsi que le degr dintelligibilit dans le bruit. Le niveau de prvisibilit des phrases a t mesur an de sassurer que la diffrence de performance entre les phrases hautement prvisibles et faiblement prvisibles soit quivalente entre les listes. Daprs les rsultats obtenus avec un sous-groupe de participants adultes, on croit que les listes de phrases mises au point avec cet essai pourront tre utiles la recherche sur lorigine des problmes auditifs ou linguistiques sous-jacents de perception de la parole dans le bruit parmi la population canadienne-franaise. Cependant, les rsultats actuels devraient tre interprts avec prudence, car seulement des personnes avec une acuit auditive normale ont particip aux expriences. Les rsultats pourraient ne pas sappliquer aux personnes souffrant de problmes de perception de la parole dans le bruit. Des valuations supplmentaires des proprits psychomtriques du test doivent tre effectues avant son application clinique. Nanmoins, ces rsultats prliminaires suggrent que la poursuite de llaboration du Test de phrases dans le bruit est justie.
Key words: speech in noise tests, language-based competencies, linguistic context

a ny i n d iv i d u a l s re p o r t d i f f i c u l t y understanding speech in noise. For some of them, their speech perception problems in noise can be explained by their audiogram. For others, the underlying nature of their difculties is not as obvious. In these cases, a better understanding of the listening problems may improve service delivery. The Speech Perception In Noise (SPIN) test was originally developed to assess how well individuals with acquired peripheral hearing loss utilize contextual linguistic information to understand speech in noise (Elliott, 1995; Kalikow, Stevens & Elliott, 1977). The original test materials consist of ten tape-recorded lists of 50 sentences mixed with a twelve-talker speech babble. When the SPIN test is administered, the listener is asked to repeat the nal word (key word) for each sentence. In each list, half of the sentences are highly predictable (HP) as they contain contextual linguistic information that facilitates the identication of the key word (e.g., The candle ame melted the wax). The other half of the list is composed of low predictability (LP) sentences (e.g., Paul cant discuss the wax), which contain little contextual linguistic information (Kalikow et al., 1977). The SPIN test was developed on the premise that speech perception involves at least two types of processes: 1) the auditory processing of the signal and, 2) the languagebased processing of that information (Kalikow et al., 1977). According to Kalikow et al. (1977), the recognition of the nal word of the HP sentences can be accomplished through one or both of these operations, while the recognition of the LP sentences key word depends mainly on the auditory processing of the signal. The level of the babble noise at which the test is conducted can be varied while presenting the different lists of the SPIN sentences. This test manipulation is relevant for determining the extent to which responses for each type of sentences are affected by the signal-to-noise ratio (SNR; Kalikow et al., 1977). Since the two types of sentences of the SPIN test only differ by the semantic and syntactic content, it is possible to determine the extent to which the listener benets from the contextual linguistic information by analyzing the difference of the performance for the HP and LP sentences (Kalikow et al., 1977). Although the use of linguistic contextual cues is only one component of the top-down processing involved in the speech recognition process, it is at least possible to measure this listeners competency with the SPIN test, which is not the case with the other available speech in noise tests. The original version of the SPIN test and the SPIN-R test (the revised version of the SPIN test by Bilger, Nuetzel, Rabinowitz & Rzeczkowski, 1984) have been used in many studies to explore the underlying origins of the speech perception problems in noise. For instance, it has been employed in studies conducted among populations of younger and older adults with normal hearing sensitivity thresholds (Dubno, Ahlstrom & Horwitz, 2000; Humes, Burk, Coughlin, Busey, & Strauser, 2007; Kalikow et al., 1977; Pichora-Fuller, 2008; Pichora-Fuller, Schneider

& Daneman, 1995), adults with permanent hearing impairment (Bilger et al., 1984; Schum & Matthews, 1992), as well as adults with learning difculties (Elliott & Busse, 1987). According to the results obtained with the SPIN test, the speech understanding difculties experienced by these populations were related to underlying auditory decits. On the other hand, comparisons of the results obtained by native listeners (listeners who learned American English from birth) and non-native listeners (listeners who learned American English later in life) on the SPIN test have lead to different outcomes. The results revealed that the levels of noise at which speech is intelligible are signicantly higher for the native listeners compared to the non-native listeners (Bradlow & Alexander, 2007; Florentine, 1985; Mayo, Florentine & Buus, 1997). It was also observed that the benet from linguistic context is signicantly greater for the native listeners compared to the non-native listeners. The SPIN test provides a method of delineating the relative contribution of the auditory and the language-based function involved in speech understanding in noise. At this point, there is no test available in Canadian French that is comparable to the SPIN test. A simple translation of the SPIN test sentences would not have been valid because of the differences in the linguistic structure and vocabulary between English and French. It was therefore necessary to develop a French adaptation of the SPIN test. A similar approach to the one used for the development of the original version of the SPIN test was taken to establish the Test de Phrases dans le Bruit (TPB). This paper describes the development of the TPB, which consists of ve French lists of forty recorded-sentences and a speech babble.
The Development of the TPB
The approach used to develop the test lists of the TPB involved the measurement of the intelligibility of the key words in noise (Experiment 1), the evaluation of the difference between the scores obtained on the HP and the LP sentences (Experiment 2) and the verication of the performance on the TPB at various SNRs (Experiment 3). The series of experiments that lead to the development of the preliminary version of the TPB is described below.
Development of the Speech Materials
According to Kalikow et al. (1977), to simplify the task and to minimize the inuence of linguistic and memory skills, the type of response to be required from the subject has to be a single word response. As for the SPIN test, it was determined that the response word for the TPB would be the last word of the sentence. This type of response is also convenient for the examiner as the scoring simply requires matching the response with the nal word of the test sentence (Kalikow et al., 1977). In order to further control the linguistic content of the sentences, another restriction was that the key word had to be a monosyllabic word. Moreover, all the sentences were constrained to contain six to eight syllables. As opposed to the SPIN test, which was developed for unilateral presentation of the sentences and the babble

Revue canadienne dorthophonie et daudiologie - Vol. 34, No 4, Hiver 2010
noise, a bilateral presentation mode was selected for the TPB. This option was chosen based on the poor ecological validity of unilateral presentation when testing speech in noise (Besing, Koenke, Abouchacra, & Letowski, 1998; Jerger, Greenwald, Wamback, Seipel, & Moncrieff, 2000). Because the familiarity of the words inuence their intelligibility when they are presented in noise (Elliott et al., 1979; Epstein, Giolas & Owens, 1968; Kalikow et al., 1977), all the key words chosen for the test material were selected from the MANULEX database (Lt, Sprenger-Charolles, & Col, 2004). The MANULEX is a web database listing word frequency values for 48,886 lexical entries encountered in 54 French books used in European French elementary schools (Lt et al., 2004). No such large database was available for words used in Canadian French children literature. Monosyllabic words with a frequency of use within the range of 7.7 to 935.4 per million words were selected from the MANULEX. The initial pool consisted of 200 key words. Within the constraints previously noted, a set of 200 HP sentences was developed (e.g., Elle met la nappe sur la table), as well as a set of 200 LP sentences (e.g.: Jai achet une nouvelle table). The resulting corpus of 400 sentences was analyzed by two grade 3 teachers (i.e., teaching children of eight to nine years of age), who were speakers of Canadian French, to conrm the naturalness of the sentences. The teachers were also invited to provide suggestions to improve the naturalness of the sentence where needed. They were asked to take into account that the TPB was to be used with children and adults. Following the revision of the sentence naturalness, nine female native Canadian French speakers aged from 9 to 11 years completed a paper-and-pencil test to conrm the predictability of the sentences. The 400 sentences were listed on answer sheets with the key word deleted. Participants were instructed to ll in the blank with a word that they thought would most likely occur at the end. For each of the HP sentences, if none of the participants had written the intended key word, the sentence was reworked to be more predictable. For each of the LP sentence, if one participant had written the intended key word, the sentence was reworked to be less predictable. It was determined that the sentences should be recorded by a female speaker because of the predominance of female educators and caregivers in childrens education (Fallon, Trehub & Schneider, 2000). A female speaker of Canadian French who had previously participated in similar recording sessions was chosen to produce the 400 revised sentences. The sentences were recorded in a quiet recording room at the University of Montreal, with a digital video camcorder (Canon GL2, Canon Canada, Mississauga, ON L5T1P7) to which an external lapel microphone (Audiotechnica Pro70, Tokyo, Japan) was connected. During the recording session, the camera was positioned at approximately 2.5 meters in front of the speaker. The microphone was hanging from the ceiling, positioned at approximately 0.5 meters in front of the speaker. The speaker was instructed

to articulate each sentence as naturally and as clearly as possible. The recordings were then organized into 400 individual sentence les using the iMovie 4 software (Apple Canada, Markham, ON L3R 5G2). To ensure a uniform level across the stimuli, the key words were edited with the Cool Edit Pro software (Cool Edit Pro version 2.1, Adobe Systems Canada, Toronto, ON M8X 2X3) to be within 2 dB of the root mean square average level (68.3 dB SPL) of the 400 key words. Since the key words were selected from the European French MANULEX database, a test of word familiarity was conducted with a group of children who were speakers of Canadian French. This verication was necessary because of the cultural differences between European and Canadian French. Five lists of 40 key words were developed for the familiarity test. The key words were all taken from the recorded LP sentences audio les to ensure, as much as possible, a similar accentuation on each word. The ve lists of key words were burned to individual audio compact discs (CD). Forty children (19 girls and 21 boys) ranging from 5.5 to 7.4 years of age (average of 6.5 years) participated in this study. A parent of each participant signed the consent form and completed a questionnaire. Each participant was tested individually in a quiet room where ambient noise level did not exceed the specications for hearing screening in schools (ASHA, 1997). A hearing screening at the intensity level of 20 dB hearing level (HL) was performed with a portable audiometer (Maico MA 41, Maico GmbH, 10587 Berlin, Germany; Beltone AE2, Beltone, Glenview IL 60026) with TDH-39 headphones (Telephonics, Farmingdale, NY 11735) prior to the experiment. All participants had normal hearing sensitivity at 500, 1000, 2000 and 4000 Hz bilaterally. The exclusion criteria for this study were any history of language disorders, otological problems, attention disorders or general learning delays. Four lists were presented monaurally to each participant (two lists per ear) via a CD player (Panasonic RX-D27, Mississauga, ON, L4W 2T3) connected to the portable audiometer set at 60 dB HL and a pair of headphones. The listener was instructed to report each word that was presented and to guess if necessary. A total of 160 words out of the 200 were correctly identied by over 80% of the participants. This suggested that the majority of the selected words were familiar to Canadian French children of ve to seven years old. Following the familiarity testing of the key words, 60 words were removed from the corpus on the basis of different considerations: (a) words with a frequency of use score of less than 10 per millions words (according to the MANULEX database) yielding a recognition score of less than 50%, (b) homonymous words like boue and bout and (c) words with different pronunciation across Canadian French communities (e.g., zoo, oeuf, clown). This eliminated 120 sentences from the pool of recorded sentences because each key word appeared once in a HP and once in a LP sentence. The remaining 280 sentences were divided into seven lists of 40 sentences, ensuring that the familiarity value

Procedure
Each participant was tested individually in an audiometric suite, using the same audiometer 80 and headphones as for the hearing screening. The sentences were transmitted via one CD 70 player (Panasonic RX-D27) connected to the 60 audiometer. The speech babble was conveyed via another CD player (TASCAM CD-A500, TEAC 50 Canada, Mississauga, ON L4Z 1Z8) connected to 40 a different audio-input channel of the audiometer. The seven lists of 40 sentences were presented 30 at a SNR of 0 dB (the sentences and the speech babble at 65 dB HL) with monaural right ear 20 presentation. The selection of the SNR of 0 dB 10 was based on Kalikow et al.s (1977) work for the SPIN test. The speech babble of European 0 French talkers (4 females and 4 males) by Perrin 7 and Grimault (2005) was used.

A repeated-measure, two-way analysis Ten Canadian French speaking adults (ve females of variance (ANOVA) was performed on the mean average and ve males) between 19 and 28 years of age (average score obtained for the HP sentences and the LP sentences of 22 years) were recruited for the measurement of the key at each list.

A sample of 14 adults (11 females and 3 males) between 21 to 27 years of age (average of 23 years), speakers of Canadian French, was recruited for this study. None of the participants had taken part in Experiment 1. Prior to the experiment, participants were asked to sign the consent form and to complete a questionnaire to rule out any exclusion criteria. The inclusion and exclusion criteria used to recruit the participants were the same as Experiment 1.
Each participant was tested individually in an audiometric suite with the same Lists equipment as in Experiment 1.

A total of 80 sentences were removed from the corpus (i.e., 40 key words), based on these individual analyses. The remaining 100 HP sentences and 100 LP sentences were assembled into ve lists of 40 sentences, ensuring an even distribution of the key words according to their familiarity and intelligibility in noise values (from Experiment 1). Precautions were also taken for having equivalent means of the difference scores between the HP and LP sentences across the lists (from the results obtained in Experiment 2). The ve lists were recorded on one CD, each list on a different track. This constituted the preliminary version of the sentence lists set of the TPB (see a sample of the TPB lists in Table 1). The performance at various SNRs had to be veried. This verication is described in the following section.

Experiment 3 Verication of the Performance on the TPB at Various SNRs

The objective of this experiment was to verify the performance on each type of sentence as a function of SNR.
A group of 22 Canadian French speaking adults was recruited for this study. None of them had taken part in Experiment 1 or 2. The age range extended from 19 to 43
years (average of 27 years). As for the previous experiments, all the participants were required to sign a consent form and to complete a questionnaire to rule out the presence of any exclusion criteria. The inclusion and exclusion criteria were the same as those used for the Experiment 1. Seven participants had to be excluded from the study. Two participants reported a diagnosis of attention disorder during their childhood. One participant failed the audiological screening assessment. The data from four participants were discarded because they only completed

In total, the data from 15 participants (nine females and 6 males) were included in the analyses.
This experiment was conducted in a quiet room at the Universit du Qubec Trois-Rivires (Qubec, Canada), which met the ANSI S3.1-1999 (R2008) specications. The same equipment used for Experiment 1 and 2 was employed, i.e., Midimate 622 audiometer and TDH 39 headphones. The audiometer was connected to two Panasonic RX-D27 CD players. For this experiment, the testing conditions were similar to those of the TPB, i.e., bilateral presentation of the sentences and the noise. A local audiometric equipment company (Genie Audio Inc., Saint-Laurent, QC H4N 1T1) was consulted and developed an audio mixer that allowed bilateral presentation of both the test stimuli and the masking noise as well as an independent control of the intensity level of each one. Each participant was tested individually with the ve lists of the TPB and the same speech babble (Perrin & Grimault, 2005) as for the previous experiments. All the participants listened to each of the ve lists presented at ve different SNRs, i.e.: -6, -4, -2, 0 and +2 dB. The sentences lists were always presented at 60 dB HL. The order of presentation of the lists and SNRs was partially counterbalanced across the participants (based on a Latin Square design). The sentences and the babble noise were presented bilaterally.

Results

Mean results for the experiment are summarized in Figure 3. The percent correct word recognition scores for the HP and LP sentences obtained at each SNR are provided. The most consistent nding was that the mean average of the correct scores for the HP sentences was higher than
for the LP sentences percentage at the ve tested SNRs. A repeated-measures two-way ANOVA was performed on the mean average score obtained for the HP and the LP sentences at each SNR to test the statistical signicance of these trends. The analysis of variance was conducted with two within-subject factors: Type of sentences (HP and LP sentences) and SNR (ve levels corresponding to the ve tested SNRs). The analysis revealed a signicant main effect of Type of sentences [F (1,56) = 268.35, p<.001, 2= 0.95] and a signicant main effect of SNR [F(4,56) = 273.97, p<.001, 2= 0.95]. The interaction of the Type of sentence x SNR was also signicant [F(2.3,56) = 8.46, p<.001, 2= 0.38], suggesting that the difference score between the two types of sentences was inuenced by the SNR. This was probably caused by the oor and ceiling effects of the performance-intensity function. For example, at -6 dB SNR, the performance for both LP and HP items approached 0%, reducing the difference of score between the two types of sentences. Additional analyses were conducted to explore the nature of the Type of sentence x SNR interaction. This was accomplished by comparing the performance of the HP and the LP sentences at each SNR. Five paired t-tests indicated that the performance for the HP sentences were signicantly different from the performance obtained with the LP sentences at each of the ve SNRs tested, using the Bonferroni correction (critical alpha level of 0.01). As in other studies on speech recognition performance (Boothroyd & Nittrouer, 1988; Laroche et al., 2003; Mayo et al., 1997), the mean percent correct scores for each type of sentences at each SNR was transformed into z scores. The z scores as a function of the SNR for each type of sentence is illustrated in the left panel of Figure 4. A linear regression function was calculated with the z scores. As shown in Figure 4, the data were well tted by the linear regression function. The r2 variance accounted for was over 0.9. The functions obtained for the HP and the LP sentences roughly showed a similar slope, i.e., 0.381 z/dB for the HP sentences and 0.400 z/dB for the LP sentences. From the linear regression function, the z-scores were converted back to percentages to produce the intelligibility ogive (cumulative frequency) plots for the LP and HP sentences, as shown in the right panel of Figure 4. The data obtained with the HP and LP sentences of the TPB provided typical ogive speech intelligibility functions as the SNR increased. Based on these functions, it is noted that 50% key word intelligibility is reached at a lower SNR with the HP sentences (-2.8 dB) than with the LP sentences (-0.85 dB). This difference of SNR illustrates the contribution of the linguistic contextual information to auditory speech perception. Difference scores were used in other studies to characterize the gain in speech perception performance attributable to the provision of additional linguistic and contextual cues (Elliott & Busse, 1987; Erber, 1975; PichoraFuller, 2008; Pichora-Fuller et al., 1995) or by the provision of visual information (Gagn, Tugby, & Michaud, 1991; Ross, Saint-Amour, Leavitt, Javitt, & Foxe, 2007). Therefore,

HP-LP difference score

an HP-LP sentences difference score was computed from the ogive functions illustrated on the right panel of Figure 4. The plot of the HP-LP difference of scores as a function of SNR is illustrated in Figure 5. The plot reveals an inverted u-shaped relationship between the gain in recognition accuracy due to the HP sentences additional linguistic contextual cues and the SNR. Using the difference score measure, it appears that the maximum benet of the linguistic contextual cues for this group of listeners occurs at the center of the curve, at the SNR of -1.5 dB, with a gain of 25%. This observation is attributable to the particular test conditions used in the present experiment.

Discussion

This paper described the development of the TPB, which is a French adaptation of the SPIN test. SPIN-like tests provide a useful and time-tested way to measure speech recognition performance in the presence of background noise. The results obtained from the TPB may be analyzed from different perspectives, for example, by studying the difference between the scores on HP and LP sentences as a function of SNR. This perspective illustrates the contribution of language knowledge and ability to use the linguistic context of the HP sentences to understand speech (Elliott & Busse, 1987). It also shows at which SNR the listener benets the most from the linguistic and contextual cues (Pichora-Fuller, 2008; Pichora-Fuller et al., 1995). For the group of adults who participated in this study, it appears that the maximum benet of the linguistic contextual cues occurs at the SNR of -1.5 dB, with a gain of 25%. This observation is limited to the particular test conditions of the present study. However, in the case of listeners with hearing problems, the maximal difference score may fall at a different SNR because of the shift in the listeners performance-SNR curve and the possible difference in slope of the LP and HP curves. Moreover, in the case of listeners who cannot benet from the linguistic contextual cues because of a language decit, the magnitude of the difference scores between the HP and LP sentences may be lower. The exploration of the speech perception problems experienced by individuals with auditory processing disorder (APD) counts among the applications of the TPB. The American Speech-Language-Hearing Association (2005) describes APD as difculties in the perceptual processing of auditory information at the level of the central auditory nervous system. However, at the present time, the results of available studies have not specically and unequivocally identied the underlying causes of the reported speech perception problems in noise reported by individuals with APD. If the underlying dysfunction in the case of APD is related to the auditory processing of the acoustic speech signal and not to the languagebased processing, listeners with APD should be equally competent at using linguistic contextual cues at the TPB as individuals without listening problems. At present, many general intervention programs proposed for the rehabilitation and management of APD include procedures

to increase auditory closure abilities in order to improve the use of linguistic contextual information to facilitate speech perception in noise. Auditory closure refers to the recognition of complete words, or utterances, when only parts are spoken or heard (Delk, 1991). However, if the TPB results demonstrate that listeners with APD have similar auditory closure abilities as control groups, such intervention may not be required. Findings of this sort would guide the professionals involved with listeners presenting with APD to develop more effective intervention plans. The TPB could also be used with other populations with speech perception problems in noise, to investigate their auditory closure skills which is not possible with other available French speech in noise tests. However, more testing with these clinical populations will be necessary to determine the diagnostic properties and accuracy of the TPB. Additional evaluations of the psychometric properties and diagnostic usefulness of the TPB must be performed before it can be routinely applied in research and clinical applications. First, the equivalencies of the actual lists have to be measured in more detail. Second, in order to ensure that the TPB is appropriate for children, the test will have to be evaluated with that population. Normative data will also have to be collected for both the adult and children populations before its routine use, to allow comparison of performance measured with populations presenting with speech perception problems in noise. Moreover, for the data collection, additional validation for different dialects of French (other than Canadian French) may have to be undertaken, as the performance on the TPB may be inuenced by the dialect, like any other speech perception test.

Conclusion

The objective of this paper was to describe the initial steps used to develop the TPB. The present ndings should be interpreted with caution as only individuals with normal hearing function participated in the experiments. Additional evaluations of the psychometric properties of the test have to be performed before its clinical applications. Nevertheless, the preliminary ndings suggest that further development of the TPB is warranted. The sentence lists that resulted from the research described here will be useful for the exploration of the underlying auditory and/or languagebased origins of speech perception problems in noise for speakers of Canadian French. A better understanding of the perception of speech in noise may inform the development of more specic and effective intervention programs.
