Fricative consonants: acoustic and X-ray measurements

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...

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...

Noise source models for fricative consonants

Hybrid source models for fricative consonants are derived based on aeroacoustic principles of sound generation employing vocal tract area functions obtained from magnetic resonance imaging data of voiced and unvoiced English fricatives. Results based on data from a male and a female subject indicate that a linear source-filter model is fairly adequate for capturing essential spectral characteri...
