This report on speech research contains papers describing experiments involving both information processing and speech production. The papers concerned with information processing cover such topics as peripheral and central processes in vision, separate speech and nonspeech processing in dichotic listening, and dichotic fusion along an acoustic continuum. Speech production topics covered include the activity of the intrinsic laryngeal muscles in voicing control, velopharyngeal function in oral/nasal articulation and voicing gestures, laryngeal adjustments for vowel devoicing in Japanese, vowel stress and articulatory reorganization, tension in some American English vowels, and word-final stops in Thai. One paper in the collection concerns reading machines for the blind. The final paper discusses the evolution of human speech anatomy. A list of publications and reports is provided along with author and title indexes to the previous status reports on speech research. (VM)
