Offset Time

Voice onset time (VOT) and vowel duration characteristics of speakers following the Singer-Blom technique of tracheoesophageal puncture (1980) were compared to those of traditional esophageal and laryngeal speakers. Fifteen subjects in each of the three speaker groups produced the words /pik/, /kup/, and /kup/ in a carrier phrase while audio recordings were obtained. Broadband spectrograms were made of the consonant-vowel-consonant (CVC) utterances and vowel duration and VOT were measured. Analysis of variance (ANOVA) procedures revealed that the tracheoesophageal speakers produced significantly shorter VOTs and longer vowel durations than the laryngeal speakers. However, the longer vowel durations for the traeheoesophageal speakers were not completely accounted for by the shorter VOTs found for that group. Spectrographic examination suggests that delayed voice offset time for the tracheoesophageal speakers also contributes to their longer vowel durations. Overall findings indicate that the physical characteristics and motor control properties of the neoglottis, even when driven by pulmonary air as in tracheoesophageal speakers, exert a major influence on alaryngeal voice production.

Previous studies attest that some early bilinguals produce the sounds of their languages in a manner that is characterized as “compromise” with regard to monolingual speakers. The present study uses meta-analytic techniques and coronal stop data from early bilinguals in order to assess this claim. The goal was to evaluate the cumulative evidence for “compromise” voice-onset time (VOT) in the speech of early bilinguals by providing a comprehensive assessment of the literature and presenting an acoustic analysis of coronal stops from early Spanish–English bilinguals. The studies were coded for linguistic and methodological features, as well as effect sizes, and then analyzed using a cross-classified Bayesian meta-analysis. The pooled effect for “compromise” VOT was negligible (β = −0.13). The acoustic analysis of the coronal stop data showed that the early Spanish–English bilinguals often produced Spanish and English targets with mismatched features from their other language. These performance mismatches presumably occurred as a result of interlingual interactions elicited by the experimental task. Taken together, the results suggest that early bilinguals do not have “compromise” VOT, though their speech involves dynamic phonetic interactions that can surface as performance mismatches during speech production.

Acoustic Analyses

<b><i>Background/Aims:</i></b> Previous research has shown that exposure to multiple foreign accents facilitates adaptation to an untrained novel accent. One explanation is that L2 speech varies systematically such that there are commonalities in the productions of nonnative speakers, regardless of their language background. <b><i>Methods:</i></b> A systematic acoustic comparison was conducted between 3 native English speakers and 6 nonnative accents. Voice onset time, unstressed vowel duration, and formant values of stressed and unstressed vowels were analyzed, comparing each nonnative accent to the native English talkers. A subsequent perception experiment tests what effect training on regionally accented voices has on the participant’s comprehension of nonnative accented speech to investigate the importance of within-speaker variation on attunement and generalization. <b><i>Results:</i></b> Data for each measure show substantial variability across speakers, reflecting phonetic transfer from individual L1s, as well as substantial inconsistency and variability in pronunciation, rather than commonalities in their productions. Training on native English varieties did not improve participants’ accuracy in understanding nonnative speech. <b><i>Conclusion:</i></b> These findings are more consistent with a hypothesis of accent attune­ment wherein listeners track general patterns of nonnative speech rather than relying on overlapping acoustic signals between speakers.

Ten normally hearing and 10 age-matched subjects with moderate-to-severe hearing impairment were recorded producing a protocol of 18 basic syllables [/pi/,/pa/,/pu/; /bi/,/ba/,/bu/; /ti/,/ta/,/tu/; /di/,/da/,/du/; /ki/,/ka/,/ku/; /gi/,/ga/,/gu/] repeated five times. The resulting 90 syllables were digitized and measured for (a) total duration; (b) voice-onset time (VOT) of the initial consonant; (c) fundamental frequency (F 0 ) at midpoint of vowel; and (d) formant frequencies (F 1 , F 2 , F 3 ), also measured at midpoint of vowel. Statistical comparisons were conducted on (a) average values for each syllable, and (b) standard deviations. Although there were numerical differences between normally hearing and hearing-impaired groups, few differences were statistically significant.

Purpose This study examined vocal hyperfunction (VH) using voice onset time (VOT). We hypothesized that speakers with VH would produce shorter VOTs, indicating increased laryngeal tension, and more variable VOTs, indicating disordered vocal motor control. Method We enrolled 32 adult women with VH (aged 20–74 years) and 32 age- and sex-matched controls. All were speakers of American English. Participants produced vowel–consonant–vowel combinations that varied by vowel (ɑ/u) and plosive (p/b, t/d, k/g). VOT—measured at the release of the plosive to the initiation of voicing—was averaged over three repetitions of each vowel–consonant–vowel combination. The coefficient of variation (CoV), a measure of VOT variability, was also computed for each combination. Results The mean VOTs were not significantly different between the two groups; however, the CoVs were significantly greater in speakers with VH compared to controls. Voiceless CoV values were moderately correlated with clinical ratings of dysphonia ( r = .58) in speakers with VH. Conclusion Speakers with VH exhibited greater variability in phonemic voicing targets compared to vocally healthy speakers, supporting the hypothesis for disordered vocal motor control in VH. We suggest future work incorporate VOT measures when assessing auditory discrimination and auditory–motor integration deficits in VH.

Production Capacities

Purpose Child phonologists have long been interested in how tightly speech input constrains the speech production capacities of young children, and the question acquires clinical significance when children with hearing loss are considered. Children with sensorineural hearing loss often show differences in the spectral and temporal structures of their speech production, compared to children with normal hearing. The current study was designed to investigate the extent to which this problem can be explained by signal degradation. Method Ten 5-year-olds with normal hearing were recorded imitating 120 three-syllable nonwords presented in unprocessed form and as noise-vocoded signals. Target segments consisted of fricatives, stops, and vowels. Several measures were made: 2 duration measures (voice onset time and fricative length) and 4 spectral measures involving 2 segments (1st and 3rd moments of fricatives and 1st and 2nd formant frequencies for the point vowels). Results All spectral measures were affected by signal degradation, with vowel production showing the largest effects. Although a change in voice onset time was observed with vocoded signals for /d/, voicing category was not affected. Fricative duration remained constant. Conclusions Results support the hypothesis that quality of the input signal constrains the speech production capacities of young children. Consequently, it can be concluded that the production problems of children with hearing loss—including those with cochlear implants—can be explained to some extent by the degradation in the signal they hear. However, experience with both speech perception and production likely plays a role as well.

Cross Language

While crosslinguistic influence is widespread in bilingual speech production, it is less clear which aspects of representation are shared across languages, if any. Most prior work examines phonetically distinct yet phonologically similar sounds, for which phonetic convergence suggests a cross-language link within individuals [1]. Convergence is harder to assess when sounds are already similar, as with English and Cantonese initial long-lag stops. Here, the articulatory uniformity framework [2, 3, 4] is leveraged to assess whether bilinguals share an underlying laryngeal feature across languages, and describe the nature of cross-language links. Using the SpiCE corpus of spontaneous Cantonese-English bilingual speech [5], this paper asks whether Cantonese-English bilinguals exhibit uniform voice-onset time for long-lag stops within and across languages. Results indicate moderate patterns of uniformity within-language—replicating prior work [2, 6]—and weaker patterns across languages. The analysis, however, raises many questions, as correlations were generally lower compared to prior work, and talkers did not adhere to expected ordinal VOT relationships by place of articulation. Talkers also retained clear differences for /t/ and /k/, despite expectations of similarity. Yet at the same time, more of the overall variation seems to derive from individual-specific differences. While many questions remain, the uniformity framework shows promise.

Temporal Measures

This study aimed to understand which acoustic parameters of Spanish-accented English are correlated with listeners’ perception of Spanish-accentedness. Temporal differences were analyzed in multisyllabic target words spoken in sentences by 22 Spanish speakers of English and five native speakers of American English (AE). Recordings were presented to AE listeners who judged the degree of accentedness on a 9-point scale. Spearman rank order correlation showed that the listeners’ ratings of degree of accentedness in sentences correlated strongly (r= +0.82) with those in words. Listeners’ ratings of accentedness correlated in varying degrees with various temporal measures, namely Overall word durations (+0.04 to +0.56), Stressed/unstressed vowel duration ratios (–0.01 to +0.35), Voice Onset Time of stops (+0.26 to +0.36), and, closure duration (+0.29 to +0.59). Results suggest that Spanish-accented English is characterized by systematic temporal differences from native AE, and that these temporal differences contribute to the perception of accentedness. Implications of findings in improving theoretical understanding and applied practices are discussed.
