چکیده

This paper presents the use of back propagation neural network to implement voice recognition. The focus is to identify voice patterns of different people so as to recognize their voices electronically. The signals corresponding to a text phrase of a group of people are recorded in voice files on a computer using sound recording software. The information in these files is converted from time domain to frequency domain using digital signal processing techniques. The resulting preprocessed signal samples in frequency domain are then used to train a neural network to identify them from among other voice samples. Keywords-Back-propagation, feature extraction, feed-forward neural network, FFT, similarity analysis, spectral density.

Text Dependent Speaker Verification with a Hybrid HMM/ANN System

The aim of this report was to implement a text-dependent speaker verification system using speaker adapted neural networks and to evaluate the system. The idea was to use a hybrid HMM/ANN approach, i.e. Artificial Neural Networks were used to estimate Hidden Markov Model emission posterior probabilities from speech data, and the system was implemented in C++ as a module for GIVES. The report al...

On Residual CNN in Text-Dependent Speaker Verification Task

Deep learning approaches are still not very common in the speaker verification field. We investigate the possibility of using deep residual convolutional neural network with spectrograms as an input features in the text-dependent speaker verification task. Despite the fact that we were not able to surpass the baseline system in quality, we achieved a quite good results for such a new approach g...

Deep Neural Network based Text-Dependent Speaker Recognition: Preliminary Results

Recently there has significant research interest in using neural networks as feature extractors for text-dependent speaker verification. These types of systems have been shown to perform very well when a large amount of speaker data is available for training. In this work we are interested in testing the efficacy of these methods when only a small amount of training data is available. Google re...

Text-independent Speaker Verification Based on Probabilistic Neural Networks

In this paper, a text-independent Probabilistic Neural Network (PNN)-based Speaker Verification system is presented. Modular structure with a distinct PNN for each enrolled speaker is used. A gender-dependent universal background model is built to represent the impostor speakers. A detailed description of the system, as well as the time required for training and processing all the test trials i...

Deep Speaker Vectors for Semi Text-independent Speaker Verification

Recent research shows that deep neural networks (DNNs) can be used to extract deep speaker vectors (d-vectors) that preserve speaker characteristics and can be used in speaker verification. This new method has been tested on text-dependent speaker verification tasks, and improvement was reported when combined with the conventional i-vector method. This paper extends the d-vector approach to sem...
