Robust Automatic Speech Recognition Features using Complex Wavelet Packet Transform Coefficients
To improve the performance of phoneme based Automatic Speech Recognition (ASR) in noisy environment; we developed a new technique that could add robustness to clean phonemes features. These robust features are obtained from Complex Wavelet Packet Transform (CWPT) coefficients. Since the CWPT coefficients represent all different frequency bands of the input signal, decomposing the input signal i...
متن کاملSpeech Recognition using Wavelet Packet Features
In view of the growing use of automatic speech recognition in the modern society, we study various alternative representations of the speech signal that have the potential to contribute to the improvement of the recognition performance. Specifically, the main targets of the present article are to overview and evaluate the practical importance of some recently proposed, and thus less studied, wa...
متن کاملRobust Speech Recognition Using Wavelet Coefficient Features
We propose a new vein of feature vectors for robust speech recognition that use denoised wavelet coefficients. Greater robustness to unexpected additive noise or spectrum distortions begins with more robust acoustic features. The use of wavelet coefficients is motivated by human acoustic process modelling and by the ability of wavelet coefficients to capture important time and frequency feature...
متن کاملFeatures of Wavelet Packet Decomposition and Discrete Wavelet Transform for Malayalam Speech Recognition
This paper explains a study conducted based on wavelet based transform techniques. We have used discrete wavelet transform and wavelet packet decomposition. The database is created by using Malayalam (one of the south Indian Languages) language spoken words. Daubechies type of mother wavelet was used for the experiment. Six hundred and forty samples are collected, for the experiment. The featur...
متن کاملAutomatic Speech Recognition In Noisy Environments Using Wavelet Transform
The performance of speech recognition systems is mainly determined by the used acoustic feature extraction technique. Two techniques are known, namely the full-band approach and the multi-band approach using filter banks. Systems using either approach usually suffer from performance degradation in the presence of noise. In this paper, the multi-band approach using Wavelet transform is suggested...
