Title
Voice activity detection based on a family of parametric distributions
Abstract
In this letter, generalized gamma distribution (G@CD) is introduced as a new statistical model of spectral distribution to be applied to the likelihood ratio test performed in voice activity detection (VAD). A gradient-based on-line algorithm is proposed to estimate the parameters of G@CD according to the maximum likelihood criterion. Experimental results show that the VAD algorithm implemented based on G@CD outperformed those adopting other parametric distributions.
