Modeling the source for fricative consonants

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...

Parametric hybrid source models for voiced and voiceless fricative consonants

Source models for fricative consonants are derived based on aerodynamic principles of sound generation, in conjunction with vocal-tract models obtained from MRI data. Results indicate that a linear source-filter model is adequate for capturing essential spectral characteristics of sustained fricatives below 10 kHz. The hybrid source models employ a combination of acoustic monopole and dipole so...

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...
