Researchers have made several modifications to the above discussed techniques to make them less susceptible to noise, more robust and consume less time. These methods have been tested in a wide variety of applications, giving them high level of reliability and acceptability. Mel Frequency Cepstral Coefficients (MFCC), Linear Prediction Coefficients (LPC), Linear Prediction Cepstral Coefficients (LPCC), Line Spectral Frequencies (LSF), Discrete Wavelet Transform (DWT) and Perceptual Linear Prediction (PLP) are the speech feature extraction techniques that were discussed in these chapter. ![]() Therefore, acceptable classification is derived from excellent and quality features. Feature extraction is accomplished by changing the speech waveform to a form of parametric representation at a relatively minimized data rate for subsequent processing and analysis. Speaker recognition is the capability of a software or hardware to receive speech signal, identify the speaker present in the speech signal and recognize the speaker afterwards. It is characterized in adults with the production of about 14 different sounds per second via the harmonized actions of roughly 100 muscles. Speech is a complex naturally acquired human motor ability. ![]()
