[N569] Wavelet speech enhancement based on voiced/unvoiced decision

A wavelet-based speech enhancement algorithm for removing additive background noise from a single channel of noisy speech is proposed. In the algorithm, the enhancement is performed on a frame-by-frame basis, and each frame is classified into either voiced or unvoiced frame to deterimine the appropriate threshold in removing noise. The performance of the proposed algorithm is evaluated on Auror...

Unvoiced speech segregation based on CASA and spectral subtraction

Unvoiced speech separation is an important and challenging problem that has not received much attention. We propose a CASA based approach to segregate unvoiced speech from nonspeech interference. As unvoiced speech does not contain periodic signals, we first remove the periodic portions of a mixture including voiced speech. With periodic components removed, the remaining interference becomes mo...

Voiced/ Unvoiced Speech Discrimination Using Symbolic Dynamics

The aim of this study is to evaluate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of speech and thereby discriminate between voiced and unvoiced speech segments. The symbolic dynamics calculations were performed on voiced speech, unvoiced speech and silence data. Differences were found in histogram properties and complexity measures of symbol s...

Voiced/unvoiced decision algorithm for HMM-based speech synthesis

This paper introduces a novel method to improve the U/V decision method in HMM-based speech synthesis. In the conventional method, the U/V decision of each state is independently made, and a state in the middle of a vowel may be decided as unvoiced. In this paper, we propose to utilize the constraints of natural speech to improve the U/V decision inside a unit, such as syllable or phone. We use...

Monaural Voiced Speech Segregation Based on Pitch and Comb Filter

The correlogram is an important mid-level representation for periodic sounds which is widely used in sound source separation and pitch detection. However, it is very time consuming. In this paper, we presented a novel scheme for monaural voiced speech separation without computing correlograms. The noisy speech is firstly decomposing into time-frequency units. Pitch contour of the target speech ...
