An increasing amount of sociolinguistic research has been concentrated on diachronic idiolect change: the change of an individual’s dialect over time. This paper adds to this growing topic by analyzing the English idiolect change of Giada De Laurentiis, a heritage speaker of Italian. The study analyzes De Laurentiis’ LOT, START, and GOAT vowels, as well as the voice onset time (VOT) of voiceless stops [k] and [p] by measuring the utterances of the code-switched word ‘mascarpone’ across 20 seasons on television. The data reflect the influence of L2 US English (rhoticity, diphthongization, lengthened VOTs) on heritage Italian in De Laurentiis’ idiolect.

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.

ABSTRACT The purpose was to compare differences in production of plosive phonemes through the voice onset time (VOT) measurement in the speech of monolingual children, speakers of Brazilian Portuguese and bilingual children, speakers of both Brazilian Portuguese and English. The sample consisted of three monolingual children and three bilingual children; average age was 7 years. A speech emission was recorded for the investigation, which had the following vehicle phrase: “Diga ‘papa’ baixinho” (“Say ‘papa’ quietly”). Papa was then replaced by “baba”, “tata”, “dada”, “caca” and “gaga”. The measurements of the acoustic signals were performed through broadband spectrograms, and VOT was descriptively analyzed for the non-voiced sounds [p, t, k] and voiced [b, d, g] plosive sounds. Monolingual children presented higher average VOT values for [p, t, k] compared to bilingual children. For the [b, d, g] sounds, monolingual children had lower average VOT values, as compared to bilingual children. It was concluded that in the comparison of VOT measures of the speech samples, the monolingual children of Brazilian Portuguese presented higher values for the non voiced ones and lower for the voiced ones in relation to the bilingual children speakers of Brazilian Portuguese and English.

Aims and Objectives/Purpose/Research Questions: We investigate the robustness of cross-language phonetic correspondences in two bilingual communities over time, focusing on whether corresponding sounds (e.g. Mandarin /s/ and Korean /s’/) remain coupled in the face of language change, or whether the categories diverge over time in younger, more proficient bilinguals. Design/Methodology/Approach: We quantify the extent of assimilation versus independence of categories across languages by comparing bilinguals’ production of place of articulation and laryngeal contrasts in Mandarin and Korean sibilants. Distinct language-internal changes were expected on each dimension. Data and analysis: 107 speakers varying in age (aged 19–83), gender, and dialect participated in the study. Acoustic measurements (center of gravity of frication, voice onset time) and statistical analyses were performed on a total of ~11,000 tokens. Findings/Conclusions: The extent of cross-language independence differed on the two dimensions. Corresponding segments across the two languages remained tightly coupled in terms of place of articulation, even in the face of change; on the other hand, a language-internal change in the Korean laryngeal contrast left corresponding Mandarin segments unaffected, resulting in divergence of originally corresponding categories. We also found unpredicted changes on each dimension, and these changes progressed concurrently in the two languages. Originality: The study of correspondences in the context of independent sound change provides a unique perspective from which to evaluate the robustness of cross-language interaction, and the parallel analysis of two separate dimensions in two communities adds to the generalizability of results. Significance/Implications: Most changes occurred concurrently in the two languages, suggesting that similar phonetic categories across languages can remain tightly coupled, even in highly proficient bilinguals where phonetic independence is expected. However, one of the primary expected changes (voice onset time merger in Korean) did not affect corresponding segments in Mandarin, indicating that the extent of cross-language independence in phonetic correspondences may differ even within the same population. We discuss potential reasons for the different results.

This study presents a brief investigation into sex differences of speakers in the voice onset time of English plosives that are stressed in both word-initial and prevocalic position. 72 short phrases were presented to 5 men (range 25 to 37 years, mean age 34.2 yr.) and five women speakers (range 28 to 38 years, mean 32.6 yr.). Analysis showed that the women as speakers had on average, longer voice onset time values than their male peers.

This report presents a brief study into sex differences of speakers in the voice onset time of English plosives that are stressed in both word-initial and pre-vocalic positions. 36 isolated words were spoken by 5 men (age range 25 to 37 yr., M: 34.2 yr.) and 5 women speakers (age range 28 to 38 yr., M: 32.6 yr.) who were subjects. Analysis showed that the women speakers had on the average relative to the men, longer voice onset time values for voiceless plosives and shorter voice onset time values for the voiced plosives.

The human voice originates from oscillations of the vocal folds in the larynx. The duration of the voice onset (VO), called the voice onset time (VOT), is currently under investigation as a clinical indicator for correct laryngeal functionality. Different analytical approaches for computing the VOT based on endoscopic imaging were compared to determine the most reliable method to quantify automatically the transient vocal fold oscillations during VO. Transnasal endoscopic imaging in combination with a high-speed camera (8000 fps) was applied to visualize the phonation onset process. Two different definitions of VO interval were investigated. Six analytical functions were tested that approximate the envelope of the filtered or unfiltered glottal area waveform (GAW) during phonation onset. A total of 126 recordings from nine healthy males and 210 recordings from 15 healthy females were evaluated. Three criteria were analyzed to determine the most appropriate computation approach: (1) reliability of the fit function for a correct approximation of VO; (2) consistency represented by the standard deviation of VOT; and (3) accuracy of the approximation of VO. The results suggest the computation of VOT by a fourth-order polynomial approximation in the interval between 32.2 and 67.8% of the saturation amplitude of the filtered GAW.
