Speech Recognition Using the Energy and VQ
Youngsoo Hwang · The Journal of The Korea Institute of Intelligent Transport Systems · 2007
In this paper, the performance of the speech recognition and speaker adaptation methods are studied. The speech recognition using energy state and VQ(Vector Quantization) is suggested and the speaker adaptation methods(Maximum a posteriori probability estimation, linear specrum estimation) are considered. The experimental results show that recognition ration using energy state is 2-3 % better than that of general VQ.
