Acoustic structure of fricative consonants in Greek

The present study examines the temporal and spectral characteristics of Greek fricatives (duration and spectral moments, i.e. mean, variance, skewness, kurtosis) as distinctive cues for their place of articulation. The effects of voicing, speaker’s gender and post-fricative vowel on both duration and spectral moments are also investigated. The results indicate that noise duration does not disti...

An articulatory study of fricative consonants using magnetic resonance imaging

Magnetic resonance images of the vocal tract during sustained production of the fricatives/s, •, f, 0, z, 3, v, 6/by four subjects are analyzed. Measurements ofvocal-tract lengths and area functions, and morphological analyses of the vocal tract and tongue shapes for these sounds are presented. Interspeaker differences in area functions are found to be greater in the pharyngeal cavity than in t...

The formant patterns of fricative consonants

Analysis and synthesis of fricative consonants

This thesis studies and interprets the -entory of acoustic events associated with the changing vocal-tract configurations .:at characterize fricatives preceding vowels. Theoretical considerations of the articulatory, aerodynamic and acoustic aspects of the production of fricatives provide the foundation for interpreting the acoustic data. Fricative characteristics are considered with respect to...
