Describes studies of voice onset time in Spanish and an acoustic feature termed presence versus absence of an abrupt consonant onset. It is suggested that this feature may be used by the Spanish listener in making a perceptual distinction between voiced and voiceless stop consonants in multiple environments. (Author/KM)

The traditional division of the Chinese syllable into initial, final, and tone is examined. Distributional criteria are used to justify this analysis as more applicable to the Cantonese syllable than strict segmental analysis. A detailed analysis of the Cantonese final is given and implications for cross-language analyses are discussed. (CHK)

Identification of place of articulation in synthesized syllables was examined with eight normal hearing adults listening in quiet or noise and three adults with high-frequency sensorineural hearing loss. Stimuli with an appropriate second formant (F2) transition were compared with stimuli in which F2 was constant. (Author/DB)

The phonological patterns of 22 children with Down's Syndrome, aged 6-12, were tested to assess the relationships among cluster reduction, liquid simplification and sentence length, age, and intelligence quotient. Sentence length was found to be the primary predictor of cluster reduction and liquid simplification in the children's articulatory…

This article addresses the rationale for and issues related to the use of speech appliances, especially a removable speech appliance that positions the tongue to produce the correct /r/ phoneme. Research results suggest that this appliance was successful with a large group of clients. (Author/DB)

This paper examines studies of speech sound errors using traditional articulation and phonological process descriptions, focusing on the specific types of errors exhibited by young children who stutter. Approaches for treating children who exhibit both stuttering and disordered phonology are discussed, including issues of concurrent versus…

Tested the prediction that phonemic analysis skills develop as a consequence of reading instruction. The results of a series of phonological tasks that assessed children's sensitivity to subsyllabic onset and rime units, and to phonemes are described. (55 references) (GLR)

This study investigated two aspects of non-symbolic phonological knowledge (knowledge of the acoustic/perceptual space and of the articulatory/production space) in six preschool-age children with phonological disorders and six typically developing age peers. Results suggest that phonological knowledge is multifaceted, and that seemingly…

Proposes that the typologically uncommon combination of labial and palatal constriction in Twi has arisen from a convergence created by general patterns of coarticulation of consonants and vowels. This convergence has been systematized in a consonantal acoustic dimension partially independent from the original vocalic dimensions of contrast for…

Spanish voiced stops /b,d,g/ exhibit [+continuant] allophonic variants in phonetic environments that vary across modern speech varieties. It is argued here that variation in voiced stops and spirants continues to be associated very directly with physical factors in speech production as circumscribed by five phonetic correlates of spoken language…

Short-term changes in vowel fundamental frequency immediately preceding and following voiceless obstruents were examined in 30 4-year-olds, 8-year-olds, and 21-year-olds. Results suggest that fundamental frequency offset is simply an acoustic consequence of producing a voiceless obstruent preceded by a vowel since there were minimal age-related…

This treatment case study presents a 5-year-old bilingual Cantonese/English speaking boy with articulation and phonological errors. It reports two treatment phases: (1) articulation therapy; and (2) phonological therapy. Data have implications for the separateness of bilingual children's two phonological systems, and the differences between…
