Speaker Recognition Usi Features Sele
نویسنده
چکیده
A new method of text-independent speaker recognition using discriminative feature selection is proposed in this paper. The method is compared with the classical UBM-GMM and hybrid codebook approaches. The characteristics of the proposed method are as follows: feature parameters extraction, vector quantization with the growing neural gas (GNG) algorithm and discriminative feature selection (DFS) according to the uniqueness of personal features. The speaker recognition algorithms are evaluated on three databases: A2000, B2000 and King. The PLP cepstral coefficients have been used together with four channel normalization techniques. The test results showed that channel normalization techniques greatly improve the speaker recognition performance and they showed that use of discriminative features selection procedure yields significant performance compared with classical UBM-GMM and codebook hybrid approaches.

Although, speech recognition systems are widely used and their accuracies are continuously increased, there is a considerable performance gap between their accuracies and human recognition ability. This is partially due to high speaker variations in speech signal. Deep neural networks are among the best tools for acoustic modeling. Recently, using hybrid deep neural network and hidden Markov mo...
متن کاملSpeaker Adaptation in Continuous Speech Recognition Using MLLR-Based MAP Estimation
A variety of methods are used for speaker adaptation in speech recognition. In some techniques, such as MAP estimation, only the models with available training data are updated. Hence, large amounts of training data are required in order to have significant recognition improvements. In some others, such as MLLR, where several general transformations are applied to model clusters, the results ar...

Analysis and Optimization of Bottleneck Features for Speaker Recognition
Recently, Deep Neural Network (DNN) based bottleneck features proved to be very effective in i-vector based speaker recognition. However, the bottleneck feature extraction is usually fully optimized for speech rather than speaker recognition task. In this paper, we explore whether DNNs suboptimal for speech recognition can provide better bottleneck features for speaker recognition. We experimen...
