Abstract :
According to Jensen´s inequality, the Bayesian information criterion (BIC) based on the Gaussian mixture model (GMM) is applied to speaker indexing. It can utilise the advantages of BIC and GMM. Experimental results have demonstrated that it is superior to both single-Gaussian-based BIC and GMM for speaker indexing.
