Spectral methods for voice source parameters estimation
A spectral approach is proposed for voice source parameters representation and estimation. Parameter estimation is based on decomposition of the periodic and the aperiodic components of the speech signal, and on spectral modelling of the periodic component. The paper focusses on parameters estimation for the periodic component of the glottal ow. A new anticausal all-pole model of the glottal ow...
متن کاملDynamic voice source parameters in a female voice
Dynamic variations of the voice source in speech have been studied for a female speaker. The speech material consisted of syllables and sentences with varying stress patterns. The speech signal was inverse filtered and then a parameter model of the voice source was fitted as closely as possible to the inverse filtered glottal pulses. The four parameter glottal source model, the LF-model, was us...
متن کاملLongitudinal changes of selected voice source parameters
Longitudinal changes were investigated for selected voice source parameters: fundamental frequency (F0), jitter (period perturbation quotient, PPQ), shimmer (amplitude perturbation quotient, APQ) and glottal noise (normalized noise energy, NNE). Acoustic analyses were made on the sustained phonation of the Japanese vowel /a/ of 20 males and 38 females with no laryngeal disease, which were recor...
متن کاملAutomatic estimation of voice source parameters
Voice source parameters can be estimated by fitting a voice source model to the glottal flow signal which is obtained by means of inverse filtering. In this pap er we investigate the behaviour of the LF-model in a numb er of non-linear parameter estimation procedures. It is concluded that (1) the parameter estimates are robust against additive (white and narrow band) noise in the flow waveforms...
متن کاملPerceptual aspects of voice-source parameters
Both in speech synthesis and in sound coding it is often beneficial to have a measure that predicts whether, and to what extent, two sounds are different. This chapter addresses the problem of estimating the perceptual effects of small modifications to the spectral envelope of a harmonic sound. A recently proposed auditory model is investigated that transforms the physical spectrum into a patte...
