Noise Sources and Area Functions for the Synthesis of Fricative Consonants
نویسندگان
چکیده
In this study, we characterize the noise sources and the critical parts of vocal tract area functions for the synthesis of voiceless fricatives. We derive these characteristics indirectly by fitting synthetic to natural fricative spectra in an interactive procedure. The adjustable parameters are the number, location, type, amplitude, and spectral shape of the noise sources as well as the cross-sectional areas of the vocal tract. From the results of these experiments we derive a model for the calculation of noise source parameters for an articulatory speech synthesizer.

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...

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...
متن کاملParametric 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...
متن کاملArticulatory variability and fricative noise in apical vowels
Standard Mandarin (SM) apical vowels have tongue postures similar to the fricative consonants that obligatorily precede them, but are thought to lack the consonants’ fricative noise. Lee-Kim [10] argues that in SM apical vowels, a slight reduction of constriction at the tongue blade or tip reduces fricative noise, essentially resulting in syllabic approximants. Using lingual ultrasound to exami...

Objectives: The present research aims to study the normal development of Percentage of Consonant Correct (PCC) in Kurdish-speaking children, with Middle Kurmanji-Mukryani Dialect as an Articulation Competency Index (ACI). PCC was examined in terms of the manner of articulation and position of sound in the word. Methods: In this descriptoanalytical cross-sectional study, 120 Kurdish-speak...
