In the speech production model proposed by [Levelt, W. J. M., Roelofs, A., Meyer, A. S. (1999). A theory of lexical access in speech production. "Behavioral and Brain Sciences," 22, pp. 1-75.], syllables play a crucial role at the interface of phonological and phonetic encoding. At this interface, abstract phonological syllables are translated…

Previous studies have indicated that consonant imprecision in Parkinson's disease (PD) may result from a reduction in amplitude of lingual movements or articulatory undershoot. While this has been postulated, direct measurement of the tongue's contact with the hard palate during speech production has not been undertaken. Therefore, the present…

This paper presents a single-subject case study illustrating the need to closely examine effects of dialect from syllable position on l-colouring, and the effects of domain-initial strengthening in General American English. Most investigators report lighter /l/ tokens in syllable onsets and darker tokens in coda positions in isolated words. The…

The article reviews and evaluates several published reports of both formal research and clinical experience on phonetic and other linguistic factors that promote correct production of an inconsistently articulated "error" sound in children's speech. (Author/SB)

Twenty-one normally developing 3-year-old children were tested on two approximate consonant contrasts, "rake-lake" and "wake-rake," and a control contrast, "wake-bake." The children showed very accurate perceptions of minimal pairs. Children who did not yet articulate "r" or "l" appropriately showed somewhat less consistent perception than…

Assessment of tongue strength and endurance is common in research and clinical contexts. It is unclear whether the results reveal discrete function by the tongue or combined abilities of the tongue and jaw. One way to isolate the movement of the tongue is to constrain the jaw kinematically by using a bite block. In this study, 10 neurologically…

The observation of a syllable frequency effect in naming latencies has been an argument in favor of a functional role of stored syllables in speech production. Accordingly, various theoretical models postulate that a repository of syllable representations is accessed during phonetic encoding. However, the direct empirical evidence for locating the…

Conditions favoring the development of the three major types of vowel-harmony systems: horizontal, palatal, and labial are examined in terms of correlations between sonority, contiguity, or phonetic distance on the one hand and relative assimilability of vowels on the other. Broadly speaking, the less sonorous, the more contiguous, and the closer…

Second part of a continued article. (SK)

Summarizes the 16 parameters hypothesized to be necessary and sufficient for linguistic phonetic specifications. Suggests seven parameters affecting tongue shapes, three determining the positions of the lips, one controlling the position of the velum, four varying laryngeal actions, and one controlling respiratory activity.

This study investigated acoustic-phonetics of coronal stop production by adult simultaneous bilingual and monolingual speakers of Canadian English (CE) and Canadian French (CF). Differences in the phonetics of CF and CE include voicing and place of articulation distinctions. CE has a two-way voicing distinction (in syllable initial position)…

A detailed analysis of the oral vowels in the French phoentic system and their nasal equivalents. (Text is in French.) (PMP)

Traces the history of glottal sounds in humans, and examines some of the functions of the glottal stop in modern languages, particularly French. (AM)
