Analysis of Sanskrit sentences as spoken by 10 Sanskrit speakers supports grammarians' theory on the duration of short, long, and prolated vowel sounds, but does not provide support for the theory that all consonants are of equal duration. (Author/JDD)

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.…

A study of electromyographic (EMG) activity and palatal movement is reported. Motion pictures were taken of the nasal surface of the soft palate and EMG recordings from the levator palatini muscle were obtained. Both were analyzed for the relationship of velar height to EMG strength and time. (SC)

One English speaking child's phonological, semantic, and syntactical development from 15 to 21 months old is detailed in order to investigate the development of the mid vowel categories in English as reflected in spontaneous speech production. Prior research on this topic is summarized to reveal certain trends in the development of mid vowels.…

Shows that vowel duration is a cue to voicing of syllable-final consonants. Notes that the effective duration of a vowel apparently extends over all parts of the acoustic signal, including the transitions reflecting the consequences of the coarticulation of vowel and consonant. (Author/RL)

This study found that clinician-generated SPINE (Speech Intelligibility Evaluation) test scores were correlated with objective computer-generated measures of tongue deviancy during vowel production in 28 persons (ages 14-20) with severe/profound hearing loss. Data suggest that subjects were more deviant in their production of front vowels than…

It has been hypothesized that lax vowels may be relatively unaffected by dysarthria, owing to the reduced vocal tract shapes required for these phonetic events (G. S. Turner, K. Tjaden, & G. Weismer, 1995). It also has been suggested that lax vowels may be especially susceptible to speech mode effects (M. A. Picheny, N. I. Durlach, & L. D. Braida,…

The ability of speakers to exaggerate speech sounds ("hyperarticulation") has led to the theory that the targets themselves must be hyperarticulated. Johnson, Flemming, and Wright (1993) found that perceptual "best exemplar" choices for vowels were more extreme than listeners' own productions. Our first experiment, using their…

Cerebellum plays an important role in speech motor control. Various tasks like sustained phonation, diadochokinesis and conversation have been used to tap the speech timing abilities of dysarthric clients with cerebellar lesion. It has recently been proposed that not all areas of the cerebellum may be involved in speech motor control; especially…

This test, conducted to prove that closed vowels can be heard in fricative utterances as open vowels in explosive utterances, gives further evidence for the closing action of constrictives and the opening action of occlusives. It also reveals a possible articulatory and auditive convergence between consonants and vowels. (Text is in French.)…

The purpose of this guide is to teach English speakers accurate pronunciation of the Modern Standard Arabic phonemes. Included are discussions concerning attitudes toward language learning in general, basic linguistic concepts, a descriptive survey of the phonemes with detailed instructions for their production, and lists of minimal pairs…
