Speech Research

This report is one of a series on the progress of studies on the nature of speech, instrumentation for its investigation, and practical applications. Manuscripts cover the following topics: Identification of Sine-wave Analogues of Speech Sounds; Prosodic Information for Vowel Identity; Progressive Changes in Articulatory Patterns in Verbal Apraxia; Temporal Coordination of Phonation and Articulation in a Case of Verbal Apraxia -- A voice onset time study; Factors in the Maintenance and Cessation of Voicing; Influence of Tempo on Stop Closure Duration as a Cue for Voicing and Place; Reading Reversals and Dyslexia; The Noncategorical Perception of Tone Categories in Thai; Effect of Speaking Rate on Vowel Formant Movements; Effects of Transition Length on Identification and Discrimination within a Place Continuum; Perceptual Integration and Differentiation of Spectral Information across Intervocalic Stop Closure Intervals; Musical Skill and the Categorical Perception of Harmonic Mode; Phonetic and Auditory Aspects of Adaptation -- Evidence from Thai voicing contrasts; Hemispheric Specialization for Speech Perception in Kindergarten Children with Language Deficiency; Can the Intrinsic F sub 0 Differences between Vowels be Explained by Source/Tract Coupling; Relationship between Vowel and Consonant Identification when Cued by the Same Acoustic Information; and Information Conveyed by Vowels.
