Voice/Unvoice detection based on a composite-Gaussian source model of speech
Victor Ramamoorthy · 2005
A composite-Gaussian source model for speech was suggested at ICASSP-79. Based upon this model a voice/unvoiced detector is derived. This detector is an approximation to a maximum-a-posteriori sequence estimator and employs the Viterbi algorithm. This paper deals with the performance of this detector with real speech.
