The study examined the functions served by consonant assimilation and reduplication in the speech of eight language disordered boys (ages 3 to 5). (Author)

This study investigates the influence of initial and final consonants /p, b, s, z/ on the duration of four vowels /I, i, u, ae/ in 64 CVC syllables uttered by eight speakers of English from the same dialect area. The CVC stimuli were presented to the subjects in a frame sentence from a master tape. Subjects repeated each sentence immediately after…

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)

Thirty children (aged 4-10) and 10 adults repeated 2 target syllables, which were analyzed acoustically to evaluate development of identification and discrimination in children for the vowel duration cue to final consonant voicing. Results showed that category boundary, category separation, response consistency, and perceptual consistency…

Combinational characterization and statistical and computational techniques for generalizing rule analysis to the inference of rule order are applied to the problems of the reduction of the syllable-final consonants s, n, and r in Caribbean Spanish. Results show that aspiration and deletion can be seen as intrinsically ordered in both s and r…

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)

A study of consonant-vowel linkages focused on the nature of the vowel boundaries with onset and codas. Subjects judged the status of various word pairs as possible exemplars of a particular manipulation they had been taught to listen for in model nonsense words. The models were of three distinct tasks: (1) a nucleus substitution task, to replace…

Electromyographic experiments were performed indicating that durational differences between vowels that precede voiced consonants and those that precede voiceless ones are due to a sustention of muscular activity in articulation, which occurs only with vowels preceding voiced consonants. (SC)

The role of a strategy of reduplication in phonological acquisition and behavior was examined in terms of: (1) the relationship between adoption of this strategy and failure to produce nonreduplicated multisyllabic forms and final consonants, and (2) the role of reduplication in production constraints. (Author/AM)

Reports on research into perceptuo-motor control in a converse experimental situation, in which subjects were required to utter a repetitive sequence of syllables immediately prior to identifying syllables presented auditorily. Results support the notion of a unitary mechanism that processes information about certain consonant features during…

A systematic analysis of the distribution of Nancowry phonological and morphological elements at word level is presented. Included is a systematically transcribed vocabulary which is ordered according to the word roots. In the section devoted to word phonology, included topics are syllabic structure, stress placement, vowel length and nasality,…
