Abstract

Speaker recognition is the process of automatically recognizing who is speaking on the basis of individual information included in speech waves. Feature extraction for speech recognition is a subject of a major interest today; different features have been investigated in speech recognition systems. The perceptual linear predictive PLP: this technique uses three concepts from the psychophysics of hearing to derive an estimate of the auditory spectrum: (1) the critical-band spectral resolution, (2) the equal loudness curve, and (3) the intensity-loudness power law. This paper discusses the development of a speaker identification and phoneme classification system. In particular, we develop an artificial neural network: multilayer perceptron MLP using PLP coefficients of voice signal. The performance of the system has been tested in experiments using 14 Arabic phonemes, specifically the Arabic fricatives uttered by 4 Algerian native speakers. Our results demonstrates the efficiency of the PLP-MLP algorithm, a good recognition rate was obtained. [ABSTRACT FROM AUTHOR]
