Speaker Identification Based on Vector Quantization
In this paper a method of text-independent speaker recognition using discrete vector quantization is presented. The identification experiments were performed in a closed set of 599 speakers and two various types of features were tested: cepstral mean subtraction coefficients and mel-frequency cepstral coefficients. The effect of the various codebook size on the speaker identification performanc...
متن کاملAccelerating Vector Quantization Based Speaker Identification
Matching of feature vectors extracted from speech sample of an unknown speaker, with models of registered speakers is the most time consuming component of real-time speaker identification systems. Time controlling parameters are size and count of extracted test feature vectors as well as size, complexity and count of models of registered speakers. We studied vector quantization (VQ) for acceler...
متن کاملSpeaker Identification Using Vector Quantization
The use of vector quantization for speaker identification is investigated. This method differs from the known methods in that the number of centroids is not doubled but increases by 1 at every step. This enables us to obtain identification results at any number of centroids. This method is compared experimentally with the method (Lipeika and Lipeikiene, 1993a, 1993b), where feature vectors of i...
متن کاملSpeaker Identification by using Vector Quantization
This paper presents a novel method for Speaker Identification based on Vector Quantization. The Speaker Identification system consists of two phases: training phase and testing phase. Vector Quantization (VQ) is used for feature extraction in both the training and testing phases. Two variations have been used. In method A, codebooks are generated from the speech samples, which are converted int...
متن کاملRobust Speaker Identification System Based on Two-Stage Vector Quantization
This paper presents an effective method for speaker identification system. Based on the wavelet transform, the input speech signal is decomposed into several frequency bands, and then the linear predictive cepstral coefficients (LPCC) of each band are calculated. Furthermore, the cepstral mean normalization technique is applied to all computed features in order to provide similar parameter stat...
