Abstract:

Emphasis was laid on speech analysis techniques and the correlation of data from cineradiographic and spectrographic studies. These studies permitted the presentation of a simple mathematical model for describing formant frequency variations as a function of vowel duration and consonantal context. Several investigations on speech perception based on stimuli generated by the OVE II synthesizer were undertaken. One series of experiments were concerned with the discrimination of small differences in the acoustic structure of synthetic vowels and stop consonant plus vowel syllables and the results have been related to the location of stimuli in the acoustic domain with respect to phonetic boundaries. Other experiments were undertaken for the purpose of studying tonal factors of importance for perception of Swedish word accent. A similar study was concerned with French intonation. A study of auditory matching of sustained vowels with two-formant synthetic sounds is reviewed. Results support the established concept of mean pitch of the upper formants of front vowels within the limitation of the experimental procedure. Author
