Typical Range

Among other characteristics, voiced and voiceless consonants differ in voice onset time (VOT; Lisker & Abramson, 1964). In addition, in English, voiced consonants are typically followed by longer vowels than their unvoiced counterparts (Allen & Miller, 1999). In Spanish, this relationship is less systematic (Zimmerman & Sapon, 1958). In two experiments, we investigated perceptual sensitivities of English and Spanish native speakers to following vowel length (VL) in categorizing syllables that ranged from a prevoiced bilabial stop [ba] to a long-lag bilabial stop [pa]. According to our results, English speakers show sensitivity to following vowels with VLs falling within an English-typical range (Experiment 1), but not when vowels are shorter and in a Spanish-typical range (Experiment 2). Interestingly, Spanish native speakers do not show sensitivity to following VL in either condition. These results suggest that VOT-VL tradeoffs in perception reflect phonological sensitivities of listeners and are not reducible to speech rate compensation.

Considerable Individual Variation

AbstractPrevious studies of native English speakers learning Spanish as a second language (L2) document compromise voice onset time (VOT) values; however, the focus has been predominantly on voiceless stops and has almost exclusively investigated beginning and intermediate learners. This study fills a gap in the literature by considering the acquisition of VOT in both voiceless and voiced Spanish stops by long-time native English-speaking residents of Spain. Overall, the results show that the L2 speakers’ VOT values differ from those of native speakers across all stop consonants; yet L2 speakers’ productions of voiceless, as opposed to voiced, stops more closely approximate those of native speakers. Considerable individual variation is observed as no speaker achieves native-like performance overall, and no consonant is mastered by more than half of the speakers. Results are considered in light of what they contribute to our understanding of ultimate attainment of Spanish VOT, specifically, and L2 phonology more generally.

Surface Representations

In this article, we show that the generative phonological distinction between lexical and surface representation can explain apparently contradictory orders of acquisition of L2 voice and aspiration contrasts by native speakers of English. Cross-language speech perception research has shown that English speakers distinguish synthetic voice onset time counterparts of aspirated–unaspirated minimal pairs more readily than voiced–voiceless. Here, we present evidence that in the perceptual acquisition of the same Thai contrasts, English speakers acquire voicing before aspiration. These divergent orders are argued to be due to the levels of representation tapped by the methodologies employed in each case: surface representations in the earlier studies, and lexical in the present one. The resulting difference in outcomes is attributed to the presence of aspiration in surface, but not lexical, representations in English (Chomsky and Halle, 1968). To address the further question of whether allophonic aspiration in English aids in the eventual acquisition of contrastive aspiration in Thai, we compare the developmental progression of the English learners to that of native speakers of French, whose L1 contains only a voicing contrast, and no surface aspiration. The performance of the anglophone group improves over time, suggesting that L1 surface features can be lexicalized in L2 acquisition,even though they are not initially transferred across levels.

Crosslinguistic Influence

Abstract This study brings together two previously largely independent fields of multilingual language acquisition: heritage language and third language (L3) acquisition. We investigate the production of fortis and lenis stops in semi-naturalistic speech in the three languages of 20 heritage speakers (HSs) of Italian with German as a majority language and English as L3. The study aims to identify the extent to which the HSs produce distinct values across all three languages, or whether crosslinguistic influence (CLI) occurs. To this end, we compare the HSs’ voice onset time (VOT) values with those of L2 English speakers from Italy and Germany. The language triad exhibits overlapping and distinct VOT realizations, making VOT a potentially vulnerable category. Results indicate CLI from German into Italian, although a systemic difference is maintained. When speaking English, the HSs show an advantage over the Italian L2 control group, with less prevoicing and longer fortis stops, indicating a specific bilingual advantage.

Communicative Success

Speech rate (articulation rate and pauses) was examined for its relation to communicative success. Native English speakers (NSs) were paired with other NSs and with non-native speakers (NNSs). The subjects viewed a short film, the content of which they were to relay to their two partners independently. Communicative success was measured through comprehension questions addressed to the listeners at the completion of the task. Analyses indicated that although a slight majority of NSs slowed their speech rate for NNSs, they did not adjust articulation rate, but did significantly increase pause time. Neither speech rate nor articulation rate varied over the course of the narrations. Contrary to intuition, the subjects who successfully communicated the story to NNSs did not adjust their speech rate, while those who had difficulty communicating with NNSs increased pause time significantly. The implications of the findings are discussed, and suggestions for further research are made.

This chapter discusses the articulatory and acoustic properties of the sound system of Standard Modern Persian. It starts with a brief review of early work on the sound system of New Persian and its development into Modern Persian. The second section examines consonants and vowels in Standard Modern Persian. In this section, issues such as place and manner of articulation of consonants, Voice Onset Time and its importance in distinguishing voiced and voiceless obstruents, the acoustics of glottal consonants, sibilant and non-sibilant fricatives, and rhotics are discussed. The section on vowels addresses vowel space, vowel length, and the acoustics of diphthongs in Standard Modern Persian. The phonetics of the suprasegmental features of stress and intonation are the topic a final section in this chapter.

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.

The purpose of this study was to conduct an acoustic examination of the obstruent stops produced by Korean–English bilingual children in connection with the question of whether bilinguals establish distinct categories of speech sounds across languages. Stop productions were obtained from ninety children in two age ranges, five and ten years: thirty Korean–English bilinguals, thirty monolingual Koreans and thirty monolingual English speakers. Voice-Onset-Time (VOT) lag at word-initial stop and fundamental frequency (f0) in the following vowel (hereafter vowel-onset f0) were measured. The bilingual children showed different patterns of VOT in comparison to both English and Korean monolinguals, with longer VOT in their production of Korean stop consonants and shorter VOT for English. Moreover, the ten-year-old bilinguals distinguished all stop categories using both VOT and vowel-onset f0,whereas the five-year-olds tended to make stop distinctions based on VOT but not vowel-onset f0. The results of this study suggest that bilingual children at around five years of age do not yet have fully separate stop systems, and that the systems continue to evolve during the developmental period.

Abstract. Acoustic data elicited from 34 native speakers of Korean living in the United States pro-vide evidence for diachronic change in the voice onset time (VOT) of phrase-initial aspirated and lax stop phonemes. While older speakers produce aspirated and lax stops with clearly differentiated average VOT values, many younger speakers appear to have neutralized this difference, producing VOTs for aspirated stops that are substantially shorter than those of older speakers, and comparable to those for corresponding lax stops. The data further indicate that, within each age group, older speakers manifest sex-based differences in VOT while younger speakers do not. Despite this appar-ent shift in VOT values, the acoustic evidence suggests that all speakers in this study, regardless of age, continue to mark underlying differences between aspirated and lax stops in terms of stop closure and the fundamental frequency of the following vowel. It is concluded that the data point to a recent phonetic shift in the language, whereby VOT no longer serves as the primary cue to differentiate between lax and aspirated stops. There is not, however, evidence of any reorganization of the lan-guage as the phonemic level: the language's underlying lax ~ aspirated ~ tense contrasts endure.

Current research shows that listeners are generally accurate at estimating speakers’ age from their speech. This study investigates the effect of speaker first language and the role played by such speaker characteristics as fundamental frequency and speech rate. In this study English and Japanese first language speakers listened to English- and Japanese-accented English speech and estimated the speaker’s age. We find the highest correlation between real and estimated speaker age for English listeners listening to English speakers, followed by Japanese listeners listening to both English and Japanese speakers, with English listeners listening to Japanese speakers coming last. We find that Japanese speakers are estimated to be younger than the English speakers by English listeners, and that both groups of listeners estimate male speakers and speakers with a lower mean fundamental frequency to be older. These results suggest that listeners rely on sociolinguistic information in their speaker age estimations and language familiarity plays a role in their success.
