Adaptive short-time analysis-synthesis for speech enhancement
In this paper we present a new adaptive short-time Fourier analysissynthesis scheme and demonstrate its efficacy in speech enhancement. While a number of adaptive analyses have p...

Improved A Posteriori Speech Presence Probability Estimation Based on a Likelihood Ratio With Fixed Priors
Abstract--In this contribution we present an improved estimator for the speech presence probability at each time-frequency point in the short-time Fourier-transform domain. In cont...

Voice activity detection using harmonic frequency components in likelihood ratio test
This paper proposes a new statistical model-based likelihood ratio test (LRT) VAD to obtain reliable speech / non-speech decisions. In the proposed method, the likelihood ratio (L...

Speech Enhancement Using Gaussian Scale Mixture Models
This paper presents a novel probabilistic approach to speech enhancement. Instead of a deterministic logarithmic relationship, we assume a probabilistic relationship between the fr...

Speech bandwidth extension using Gaussian mixture model-based estimation of the highband mel spectrum
The quality and intelligibility of narrowband telephone speech can be enhanced by artifical bandwidth extension. This study combines Gaussian mixture model-based (GMM) mel spectr...
