Abstract

WTIMIT, which is a derivative of TIMIT emerged as a latest technique for speech quality. The technique has good wideband characteristics over a range of 50- 7 KHz. in this paper, a study on the performance of phoneme recognition system has been performed. The study includes the effect of decimating the signal to 8 KHz in the conventional case. Further it is possible to evaluate the AMR-wideband codec for several acoustic models. It is possible to propose the WTIMIT type of wideband channel data from training interactive voice receiving system.
