Contemporary Methods for Speech Parameterization by Todor Ganchev

By Todor Ganchev

Contemporary equipment for Speech Parameterization bargains a common view of short-time cepstrum-based speech parameterization and offers a standard floor for extra in-depth stories at the topic. particularly, it deals a finished description, comparative research, and empirical functionality overview of 11 modern speech parameterization tools, which compute short-time cepstrum-based speech gains.

Among those are 5 discrete wavelet packet remodel (DWPT)-based, six discrete Fourier rework (DFT)-based speech beneficial properties and a few in their versions which were used at the speech reputation, speaker acceptance, and different comparable speech processing initiatives. the most similarities and modifications of their computation are mentioned and empirical effects from functionality review in universal experimental stipulations are offered. the popularity accuracy acquired at the monophone reputation, non-stop speech acceptance and speaker attractiveness projects is contrasted opposed to the single received for the well known and wide-spread Mel Frequency Cepstral Coefficients (MFCC).

It is proven that a lot of those tools bring about speech good points that do supply aggressive functionality on a definite speech processing setup in comparison to the venerable MFCC. The final doesn't goal the promoting of definite speech positive aspects yet as an alternative goals to reinforce the typical knowing concerning the benefits and downsides of many of the speech parameterization strategies to be had this present day and to supply the root for collection of a suitable speech parameterization in each one specific case.
