A Method of Speech Signal Analysis Using Multi-level Wavelet Transform

摘要

Speech signal analysis using multi-level wavelet transform and signal decomposition is presented in this paper. This research work carried out by recording the voices of the 40 different speakers. In this work, same set of words were spoken by the speakers, those 4 words are 'Bhavana,' 'How,' 'Are,' and 'You.' From these words, features were extracted by using wavelet analysis. The results presented are based on the 800 data signals for the analysis. The study was carried out to measure the performance of the speech signal through the wavelet analysis and is reported.
