The Subject

AbstractThe nature of the links between speech production and perception has been the subject of longstanding debate. The present study investigated the articulatory parameter of tongue height and the acoustic F1–F0 difference for the phonological distinction of vowel height in American English front vowels. Multiple repetitions of /i, ɪ, e, ɛ, æ/ in [(h)Vd] sequences were recorded in seven adult speakers. Articulatory (ultrasound) and acoustic data were collected simultaneously to provide a direct comparison of variability in vowel production in both domains. Results showed idiosyncratic patterns of articulation for contrasting the three front vowel pairs /i-ɪ/, /e-ɛ/, and /ɛ-æ/ across subjects, with the degree of variability in vowel articulation comparable to that observed in the acoustics for all seven participants. However, contrary to what was expected, some speakers showed reversals for tongue height for /ɪ/-/e/ that were also reflected in acoustics, with F1 higher for /ɪ/ than for /e/. The data suggest the phonological distinction of height is conveyed via speaker-specific articulatory-acoustic patterns that do not strictly match features descriptions. However, the acoustic signal is faithful to the articulatory configuration that generated it, carrying the crucial information for perceptual contrast.

Purpose This article compares acoustic data of normally developing children from two dominant and one nondominant variety of English in order to determine phonetic proximity. Method The study focuses on one variety of American English (AE), one British English (BE) variety, and one Jamaican English (JE) variety owing to the historical and sociopolitical influences of both dominant varieties on JE. The work examines the four corner vowels (/a/, /ɑ/, /u:/, and /i:/) of the specified varieties. Speech from children aged 8–11 years was processed to extract duration, intensity, and fundamental frequency as well as the first three formants (F1, F2, and F3) of each vowel. Results Analysis of the acoustic variables showed, for the first time, that child-produced JE is phonetically closer to the variety of BE studied, than it is to the American variety. The acoustic properties of the child-produced JE vowels were found to be similar to those of adult-produced vowels, suggesting that, as has been shown for adult speech, there appears to be a limited impact of AE on JE. Conclusions This is the first acoustic study of children's speech to show that, despite the proximity to BE, the Jamaican variety is clearly a distinct variety of English. As the first study comparing AE, BE, and JE, the article provides experimental evidence of the acoustic differences in the varieties and points to the implications for automatic speech recognition and educational applications for children who speak JE.

ABSTRACT Consonant clusters occur both in Portuguese and English. However, clusters are more productive in English than in Portuguese and there are sequences which are only found in English.This study focuses on the contrasts between American English and Brazilian Portuguese consonant clusters and on three strategies Brazilian learners tend to apply when producing them: adding the high front vowel (epenthesis) between the consonants in the clusters, discarding consonants, or introducing phonetic changes. The relevance of introducing English clusters to Brazilian learners of English is pointed out and discussed under the framework of the Speech Learning Model (SLM).

Native Speech

This study aims at discussing the phonetic property of vowel quality in English, as exercised by both native speakers of General American English (AE) and non-native speakers of General American English of Serbian language background, all residents of the United States. Ten Serbian male speakers and four native male speakers of AE are recorded in separate experiments and their speech analyzed acoustically for any significant phonetic differences, looking into a set of monosyllabic English words representing nine vowels of AE. The general aim of the experiments is to evaluate the phonetic characteristics of AE vowels, with particular attention to F1 and F2 values, investigate which vowels differ most in the two groups of participants, and provide some explanations for these variations. A single most important observation that is the result of this vowel study is an evident merger of three pairs of vowels in the non-native speech: /i ɪ/, /u ʊ/, and /ɛ æ/.

Contact Effects

The disproportionate number of studies in Barcelona and the Balearic Islands observing Spanish contact effects in Catalan production, rather than Catalan contact effects in Spanish production, is an oversight of bidirectionality and the probabilistic nature of social factors in situations of language contact. Accordingly, the present study analyzes both Catalan and Spanish mid front vowel production data from Barcelona to investigate whether Catalan contact effects occur in Spanish via a process of dissimilation, and whether such effects are strengthened in younger speakers due to the relatively recent implementation of Catalan linguistic policy in the educational and public spheres. The results are suggestive of dissimilation, where phonetic distinctions are maintained between Spanish /e/ and the two Catalan mid front vowels across both F1 and F2. Additionally, analyses of variance across F1 and F2 reveal that Spanish /e/ productions across F1 are more diffuse in younger speakers and Catalan mid front vowels across F2 are less diffuse, providing evidence of reciprocity in contact effects. These results underscore the bidirectional nature of language contact and advocate for the use of variance of F1 and F2 as a metric of phonological contact effects.

Laryngeal Airway

An investigation was conducted to determine if laryngeal valving economy, as reflected in measures of laryngeal airway resistance during vowel production, differs with age in women. Seventy healthy women were studied, 10 each at age 25, 35, 45, 55, 65, 75, and 85 years. Results indicated that laryngeal airway resistance did not differ significantly with age, although it was noted that the 45-year-old women generally had lower laryngeal airway resistance values. This pattern of function differs from that observed in men (Melcon, Hoit, & Hixon, 1989). Discussion of findings includes consideration of factors that might influence laryngeal function during speech production in women. Clinical implications are offered.
