Contemporary Methods for Speech Parameterization (SpringerBriefs in Speech Technology),Used
Delivery time: 8-12 business days (International)
Contemporary Methods for Speech Parameterization offers a general view of shorttime cepstrumbased speech parameterization and provides a common ground for further indepth studies on the subject. Specifically, it offers a comprehensive description, comparative analysis, and empirical performance evaluation of eleven contemporary speech parameterization methods, which compute shorttime cepstrumbased speech features.Among these are five discrete wavelet packet transform (DWPT)based, six discrete Fourier transform (DFT)based speech features and some of their variants which have been used on the speech recognition, speaker recognition, and other related speech processing tasks. The main similarities and differences in their computation are discussed and empirical results from performance evaluation in common experimental conditions are presented. The recognition accuracy obtained on the monophone recognition, continuous speech recognition and speaker recognition tasks is contrasted against the one obtained for the wellknown and widely used Mel Frequency Cepstral Coefficients (MFCC).It is shown that many of these methods lead to speech features that do offer competitive performance on a certain speech processing setup when compared to the venerable MFCC. The last does not target the promotion of certain speech features but instead aims to enhance the common understanding about the advantages and disadvantages of the various speech parameterization techniques available today and to provide the basis for selection of an appropriate speech parameterization in each particular case.
