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.

Previous studies attest that some early bilinguals produce the sounds of their languages in a manner that is characterized as “compromised”, “intermediate” or “merged” with regard to monolingual speakers.

Complete Transformation

Emphasis (contrastive uvularisation) in Arabic spreads from an emphatic consonant to neighboring segments (Davis 1995). The effect of emphasis spread on a consonant is manifested as lowering of its spectral mean (Jongman et al. 2011). Although stop consonants reveal a strong effect of emphasis, it is not known how emphasis spread affects other acoustic properties of stops, e.g. voice onset time (VOT). Previous studies (Kulikov 2018) showed that VOT and emphasis are linked in speech production: plain /t/ in Gulf Arabic is aspirated; emphatic /ṭ/ has short-lag VOT. Phonological theory predicts that plain /t/ should become more emphatic in emphatic context, which might reduce stop VOT as well. The current study investigates the effect of emphasis spread on VOT in word-initial coronal stops in Qatari Arabic. The stimuli, produced by sixteen native speakers of Qatari Arabic, contained target plain and emphatic stops /t/, /ṭ/ followed by short or long low vowel, and plain coronal obstruents /t, s, ð/ or their emphatic counterparts /ṭ, ṣ, ð̣/. The acoustic analysis included measurements of VOT and spectral mean of burst in the stop, and F1, F2, F3 frequencies at the vowel beginning, middle and end. The results showed that final emphatic obstruent triggered emphasis spread across the syllable. The effect of emphasis on the vowel was stronger next to the emphatic obstruent (p < .01). Spectral mean of burst in plain /t/ was lower in the emphatic context (D = 276 Hz, p = .05). VOT, however, was not affected by emphasis spread. Plain /t/ had long-lag VOT averaging 52 ms; emphatic /ṭ/ had short-lag VOT averaging 17 ms. These values were not different in emphatic context (p = .743). The findings demonstrate that emphasis spread within a syllable affects only spectral characteristics of a coronal stop. Emphaticness of plain /t/ did not affect its VOT and did not result in complete transformation of the stop category

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.

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.

Univariate Analyses

This study examined phonatory-articulatory timing during sung productions by trained and untrained female singers with and without singing talent. 31 untrained female singers were divided into two groups (talented or untalented) based on the perceptual judgments of singing talent by two experienced vocal instructors. In addition to the untrained singers, 24 trained female singers were recorded singing America the Beautiful, and voice onset time was measured for selected words containing /p, b, g, k/. Univariate analyses of variance indicated that phonatory-articulatory timing, as measured with voice onset time, was different among the three groups for /g/, with the untrained-untalented singers displaying longer voice onset time than the trained singers. No other significant differences were observed across the other phonemes. Despite a significant difference observed, relatively small effect sizes and statistical power make it difficult to draw any conclusions regarding the usefulness of voice onset time as an indicator of singing talent.

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.

The purpose of this study, which focused on the wordtacoas spoken in Spanish and English, was to explore the word as a unit in second language (L2) speech acquisition. As expected, acoustic measurements revealed that Spanish and English monolinguals' renditions oftacodiffered systematically. It was also shown that the extent to which Spanish/English bilinguals approximated English phonetic norms for any one segment oftacowas correlated with their approximation for the other three segments, and that early learners differentiated Spanish versus Englishtacomore than did late learners. It also appeared that the bilinguals produced /t/ with less English-like voice onset time (VOT) values in Englishtacothan in other English words without a cognate in Spanish. In a perception experiment, listeners were able to identify the native language of Spanish and English monolinguals on the basis of their production oftaco. The listeners heard larger differences between Spanish and Englishtacotokens spoken by early than late learners of English L2. Two additional perception experiments assessed further the phonetic dimensions that listeners use to determine language identity and to gauge bilinguals' speech production accuracy. Listeners assigned to language identification and goodness rating tasks responded to acoustic information distributed over all four segments intaco, although the VOT of the word-initial /t/ appeared to be the single most important phonetic dimension. Taken together, the results of this study suggest that (a) bilinguals' accuracy in producing the various segments of a second language word may be interrelated and (b) in judging L2 speech, listeners respond to phonetic errors distributed over the entire word.

Crosslinguistic Influence

Although crosslinguistic influence (CLI) in voice onset time (VOT) production is a widely studied phenomenon (e.g. Flege, 1987), few studies look at more than two languages. This study examines the production of word-initial stops in Dutch, English and German by two groups of German L3 learners of Dutch: frequent and less frequent L3 users. The aim was to uncover evidence for CLI between Dutch and English/German by employing a picture-naming task. An acoustic analysis revealed that the frequent users produced significantly shorter voiceless stops and more prevoicing in English than the other groups did. However, all participants produced native VOTs in German, indicating that the L1 is not affected.
