Abstract : As a general aim the research sought to advance the understanding of the processes of speech perception and speech production. In particular, the report outlines work on speech alternated and switched between the ears; the development and evaluation of a masking noise with speech-envelope characteristics; the estimation of fundamental frequency by harmonic identification; the identification of utterance-final stop consonants from spectrographic displays; and vowel-formant shifts associated with the tense-nontense distinction. The script materials developed for the perceptual studies are appended. (Author)
