Research on Application of Delta Feature to Speaker Recognition
Jin Jia-bao · Audio Engineering · 2009
In most adopted methods of speaker recognition, static features of speech signal are analyzed, but the influence of speech signal's dynamic features on discernment performance is neglected. Delta features is an important feature which could reflect the inter-frame dynamic feature of speech signal. The LPC(Linear Prediction Coefficient) and Delta feature of one example are educed and analyzed, then the validity and feasibility of their application to speaker recognition are educed.
