Development Software for Preprocessing Voice Signals
Keywords:speech signal, filter, MFCC, PLP, LPCC
At present, the most important task of modern science is the creation for a person of natural means of communication with a computer, where speech input of information is carried out in the most convenient way for the user. Speech recognition is one of the challenges. As practice shows, the quality of recognition depends on the properties of the preprocessing system. To improve the quality of recognition, it is necessary to develop effective and high-speed methods and algorithms for signal preprocessing. This article proposes a new approach and algorithm for extracting features of speech signals. Based on the proposed algorithm, the identification problem is solved. In addition, the chapter presents a description of the software module for each stage of the preliminary processing of speech signals. This software is a voice-based identity tool.
