Epoch Extraction of Voiced Speech
A general theory of epoch extraction of overlapping nonidentical waveforms is presented. The theory is applied to outputs of models of voiced speech production mechanism and to actual speech data. Some typical glottal waveshapes are considered to explain their effect on the speech output. It is shown that the points of excitation of the vocal tract can be precisely identified for continuous spe...
متن کاملComparison Between Different Methods for Epoch Extraction from Speech Signal
Speech is produced by exciting the vocal tract system by an excitation source. The excitation is significant at the instants of glottal closure. These instants of significant excitation are called Epochs. Epochs play a significant role in speech processing and is used are used in many applications. There are different methods for extraction of epochs from speech signal. In this paper we have di...
متن کاملA novel method for epoch extraction from speech signals
This paper introduces a novel method of speech epoch extraction using a modified Wigner-Ville distribution. The Wigner-Ville distribution is an efficient speech representation tool with which minute speech variations can be tracked precisely. In this paper, epoch detection/extraction using accurate energy tracking, noise robustness, and the efficient speech representation properties of a modifi...
متن کاملEpoch Extraction in High Pass Filtered Speech Using Hilbert Envelope
Hilbert envelope (HE) is defined as the magnitude of the analytic signal. This work proposes HE based zero frequency filtering (ZFF) approach for the extraction of epochs in high pass filtered speech. Epochs in speech correspond to instants of significant excitation like glottal closure instants. The ZFF method for epoch extraction is based on the signal energy around the impulse at zero freque...
متن کاملAnalysis of Voiced Speech using Harmonic Models
It is very common to consider voiced speech as a periodic or quasi-periodic signal. Therefore, harmonic models are usually proposed for the modeling of this kind of speech. This paper focuses on the harmonic analysis of speech. Three models are presented and compared. The rst model is the simplest among the three models supposing that the speech signal is a stationary signal. The second model d...
