Voice Quality: Functions, Analysis and Synthesis
August 27-29, 2003
Estimation of the source of voiced speech, the glottal volume velocity waveform, with inverse filtering involves usually a parameterisation stage, where the obtained flow waveforms are expressed in numerical forms. This stage of the voice source analysis, the parameterisation of the glottal flow, is discussed in the present paper. The paper aims to give a review on the different methods developed for the parameterisation and it discusses how these parameters have reflected function of the voice source in various voice production studies.
