Contains status reports of research in three areas of speech production: functional properties of the speech production apparatus, control principles underlying speech production, and the biological basis of the speech production process. (RL)

Considers three different topics in speech research from the viewpoint of the physiology of the speech production mechanism: laryngeal control for voicing distinctions, articulatory dynamics in normal and dysarthric cases, and central mechanism of skilled movements. Includes a summary of a discussion on speech production. (RL)

Various aspects of the phonological behavior of three normal speaking and three language disordered children (ages 2 to 4) matched on the basis of mean utterance length, sex, and cognitive development, were compared. While some individual variation was noted, no substantial group differences were revealed. (Author)

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)

A universal separation of speech and language is described by the use of one mathematical frame of reference. Also described are the accruing new comparisons and measurements made possible by a theoretically adequate separation of speech and language. (Author/RM)

Reports on an experiment, conducted on ten children who misarticulated /s/, and designed to survey the effect of consonant context on misarticulation. Suggests that a context-sensitive model of phonetic performance is needed to account for variation in correct /s/ production. (Author/AM)

Takes issue with Robert DiPietro's statement on the value of generative phonology for teaching second language pronunciation in Britannica Review of Foreign Language Education,'' v1. (RS)
