In this paper, the acoustic facts of Voice Onset Time (VOT) are exemplified by looking at two virtually different languages in terms of recognizing VOT as a distinctive phonological parameter. Selected tokens of Serbian and Serbian English are recorded in carrier sentences and analysed acoustically, as spoken by four proficient Serbian speakers of EFL. The results show that, although Serbian does not recognize VOT as a parameter creating phonological distinctions, advanced non-native speakers of English are capable of learning how to relate the oral and laryngeal gestures in order to produce more native-like pronunciations of English voiceless stops in the phonetic contexts where English /p t k/ are expected to have a long lag. Special attention is drawn to CV sequences whose VOT values deviate in the two languages, as well as to those where VOTs are similar, which can be used to raise the awareness of this phonetic phenomenon in a Serbian EFL learner.

This study reports the findings of a research that was conducted on ten (10) Arab students, who were enrolled in a master of English applied linguistics program at Universiti Putra Malaysia. The research aimed at instrumentally analyzing the English stops produced by Arab learners, in terms of voice onset time (VOT); identifying the effect of their mother tongue on producing the English stops; and the extent Arabic speakers of English differentiate in terms of pronunciation between minimal pairs. The findings of the study showed that some of the subjects’ VOT values were similar to native speakers of English. It was also found that the subjects could differentiate in terms of aspiration or voicing between /p/ and /b/, which refutes the assumption that Arab learners have a problem in producing the /p/ sound with appropriate aspiration. However, they did not show significant difference in pronunciation between the /t/ and /d/ or between the /k/ and /g/. Moreover, there is a kind of limited effect of the L1 on producing some stops (e.g. /t/ and /g/). However, for the /b/ sound, it cannot be inferred that there is interference from the mother tongue because its VOT value is almost the same in English and Arabic. This research suggests that teachers need to enhance Arab learners’ pronunciation of some minimal pairs such as /t/ and /d/ or /k/ and /g/.

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.

This article presents a follow-up to Curtin et al.’s study of the perceptual acquisition of Thai laryngeal contrasts by native speakers of English, which found that subjects performed better on contrasts in voice than aspiration. This finding - surprising in light of earlier cross-linguistic voice onset time (VOT) research - was attributed to the fact that the task tapped lexical representations, which are unspecified for aspiration according to standard assumptions in generative phonology. The present study further investigated possible task effects by examining the discrimination and categorization of the same stimuli in various experimental conditions. Stimulus effects were also investigated by performing token-based analyses of the results, and by comparing them to acoustic properties of the tokens. The outcome of the discrimination experiment was the opposite of the earlier study, with significantly better performance on contrasts in aspiration than voice, even on a lexical task. A second finding of this experiment is that place of articulation interacts with the perception of the laryngeal distinctions; the aspiration distinction is discriminated better on the labials, and voice on alveolars. A parallel effect of place of articulation was also found in a categorization experiment.

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.

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.

Abstract This study reveals the existence of a Voice Onset Time shift in the Korean spoken by native speakers residing in northeast China, a shift parallel to those reported in other Korean varieties in Korea, the USA, and Canada. The VOT pattern observed in the Chinese Korean community is argued to represent a change that cannot be simply explained in terms of diffusion via recent dialect contact, or as a feature directly inherited from the source language when it was transplanted into China over a century ago. We suggest that behind the parallel VOT shifts is the power of “drift” that drives the different Korean varieties along similar journeys of language evolution. This study presents an intriguing case where internal changes driven by “drift” may actually be initiated and further supported by language/dialect contact.

Speech of late bilinguals has frequently been described in terms of cross-linguistic influence (CLI) from the native language (L1) to the second language (L2), but CLI from the L2 to the L1 has received relatively little attention. This article addresses L2 attainment and L1 attrition in voicing systems through measures of voice onset time (VOT) in two groups of Dutch–German late bilinguals in the Netherlands. One group comprises native speakers of Dutch and the other group comprises native speakers of German, and the two groups further differ in their degree of L2 immersion. The L1-German–L2-Dutch bilinguals ( N = 23) are exposed to their L2 at home and outside the home, and the L1-Dutch–L2-German bilinguals ( N = 18) are only exposed to their L2 at home. We tested L2 attainment by comparing the bilinguals’ L2 to the other bilinguals’ L1, and L1 attrition by comparing the bilinguals’ L1 to Dutch monolinguals ( N = 29) and German monolinguals ( N = 27). Our findings indicate that complete L2 immersion may be advantageous in L2 acquisition, but at the same time it may cause L1 phonetic attrition. We discuss how the results match the predictions made by Flege’s Speech Learning Model and explore how far bilinguals’ success in acquiring L2 VOT and maintaining L1 VOT depends on the immersion context, articulatory constraints and the risk of sounding foreign accented.

Aims and objectives/purpose/research questions: Many early Spanish-English bilingual speakers in the USA learn Spanish as their first language at home and English in school. This paper seeks to elucidate whether these speakers develop a separate phonological system for English and, if so, the role of primary and secondary cues in the development of the second language (L2) system. Design/methodology/approach: The phonetic realization of the voiceless stops /p/, /t/, /k/ is analyzed among three groups: early Spanish-English bilinguals; L1 English speakers who are late learners of Spanish; and L1 Spanish speakers who are late learners of English. The participants ( N = 15) engaged in a reading task and a conversation task in each language during a single recording session. Data and analysis: 1578 tokens of /p/, /t/, /k/ were extracted and analyzed using acoustic software. Voice onset time in milliseconds and center of gravity in Hertz were analyzed, and monofactorial and multifactorial analyses were performed to determine the role of linguistic background. Findings/conclusions: Evidence is found of two phonological systems among early bilingual speakers, with varying degrees of assimilation to the phonological systems of the native speakers of each language. Originality: We argue that early bilinguals construct their L2 system of /p/, /t/, /k/ in English based on the primary cue of voice onset time rather than the secondary cue of center of gravity, as they are accustomed to noticing differences in voice onset time in Spanish and because the center of gravity of /p/, /t/, /k/ in English is more variable than voice onset time, and therefore represents a more variable and less predictable cue for early bilinguals as they construct their L2 system. Significance/implications: This paper contributes to the literature on the construction of phonological systems and to research detailing the speech of early Spanish-English bilinguals.

ABSTRACTThis study examines the acquisition of production and perception by adult learners of English. The particular focus is voice onset time of initial /b/'s and /p/'s. The subjects are 10 nonnative speakers of English and six native speakers who provided identification responses to synthesized stimuli varying along a voice onset time continuum. Additionally, they each produced words with initial /b/'s and /p/'s. These measures were repeated at three 1-month intervals for the nonnative speakers. The results show that nonnative speaker perception differs from native speaker perception in two important ways: (1) stop consonants are perceived continuously rather than categorically and (2) nonnative speaker perception is influenced by the location of phoneme boundaries in both the native and target languages. Nonnative speaker production shows a greater amount of similarity to native speaker production, although, where deviations occur, nonnative speakers tend to overcompensate for differences between the native and target languages. Finally, methodological issues are raised relating to the comparison of perception and production.

This paper reports results on the acquisition of the English /p/–/b/ contrast by native speakers of Arabic. This contrast does not exist in the participants’ native language (NL). The central finding of this study is that some of the research participants exhibited a covert contrast between these segments in their interlanguage productions. That is, two of the five Arabic-speaking participants who were transcribed as having no contrast between [p] and [b] did, in fact, produce a statistically reliable distinction in voice onset time lags between the two target segments. The existence of such an intermediate stage of covert contrast in the learning of L2 phonology is eminently plausible, in view of the progressive nature of phonological acquisition. Our results help bring the learning of second-language contrasts into conformity with findings of the same phenomenon in the areas of L1 acquisition and phonologically disordered speech.
