This study investigated the influence of L1 allophonic rule, L1 segment articulation, and gender in Korean learners' production of English /s/ in two different contexts (i.e., before a high front vowel vs. elsewhere) and at three different proficiency levels in English (i.e., low vs. intermediate vs. high). The influence of the Korean allophonic…

Purpose: Mumbling as opposed to clear speech is a typical male characteristic in speech and can be the consequence of a small jaw opening. Whereas behavioral reasons have often been offered to explain sex-specific differences with respect to clear speech, the purpose of this study is to investigate a potential anatomical reason for smaller jaw…

Purpose: This study investigated children's acquisition of Hong Kong Cantonese. Method: Participants were 1,726 children ages 2;4 to 12;4 (years;months). Single-word speech samples were collected to examine 4 measures: initial consonants, final consonants, vowels/diphthongs, and lexical tones. A 2-way analysis of variance was performed to examine…

Purpose: The purpose of this study was to describe normative and validation data on the Intelligibility in Context Scale (ICS; McLeod, Harrison, & McCormack, 2012c) for English-speaking children. Method: The ICS is a 7-item, parent-report measure of children's speech intelligibility with a range of communicative partners. Data were collected…

The purpose of this study was to use acoustic analyses to describe speech outcomes over the course of 1 year after radial forearm free flap (RFFF) reconstruction of the tongue. Eighteen Canadian English-speaking females and males with reconstruction for oral cancer had speech samples recorded (pre-operative, and 1 month, 6 months, and 1 year…

Acoustic and perceptual correlates of emphasis, a secondary articulation in the posterior vocal tract, in Urban Jordanian Arabic were studied. CVC monosyllables and CV.CVC bisyllables with emphatic and plain target consonants in word-initial, word-medial and word-final positions were examined. Spectral measurements on the target vowels at vowel…

Using English as a global communicating tool makes Taiwanese people have to speak in English in diverse international situations. However, consonants and vowels in English are not all effortless for them to articulate. This phonological reduction study explores concepts about phonological (articulating system) approximation. From Taiwanese folks'…

The present study deals with the dimensions of normal and pathological phonation. Separation of normal voices from pathological voices is tested under different aspects. Using a new parametrization of voice-quality properties in the acoustic signal, the vowel productions of 534 speakers (267 M, 267 F) without any reported voice pathology and the…

Purpose: This article integrates published acoustic data on the development of vowel production. Age specific data on formant frequencies are considered in the light of information on the development of the vocal tract (VT) to create an anatomic-acoustic description of the maturation of the vowel acoustic space for English. Method: Literature…

This study examined the acoustic characteristics of vowels produced by speakers with partial glossectomy. Acoustic variables investigated included first formant (F1) frequency, second formant (F2) frequency, F1 range, F2 range and vowel space area. Data from the speakers with partial glossectomy were compared with age- and gender-matched controls.…

This investigation is a comprehensive acoustic study of 4 voiceless fricatives (/f [theta] s [esh]/) in English produced by adults and pre-and postpubescent children aged 6-14 years. Vowel duration, amplitude, and several different spectral measures (including spectral tilt and spectral moments) were examined. Of specific interest was the pattern…
