Abstract :

In this paper, the concepts of speech processing algorithms for speech signal analysis is presented. Speech analysis is performed using short-time analysis to extract features in time domain and frequency domain. The short time domain analysis is useful for computing the time domain features like energy and zero crossing rate. The different frequency or spectral components that are present in the speech signal are not directly apparent in the time domain. Hence the frequency domain representation using Fourier representation is needed. The time varying nature of spectral information in speech leads to the need for short time of Fourier transform, termed more commonly as Short time Fourier Transform (STFT).The effect of different types of windows used in short time analysis with and without overlapping and the effect of window length in speech analysis are also demonstrated.
