Integrated Phoneme Subspace Method for Speech Feature Extraction
Speech feature extraction has been a key focus in robust speech recognition research. In this work, we discuss data-driven linear feature transformations applied to feature vectors in the logarithmic mel-frequency filter bank domain. Transformations are based on principal component analysis (PCA), independent component analysis (ICA), and linear discriminant analysis (LDA). Furthermore, this pa...
متن کاملRobust Auditory-Based Speech Feature Extraction Using Independent Subspace Method
In recent years many approaches have been developed to address the problem of robust speaker recognition in adverse acoustical environments. In this paper we propose a robust auditory-based feature extraction method for speaker recognition according to the characteristics of the auditory periphery and cochlear nucleus. First, speech signals are represented based on frequency selectivity at basi...
متن کاملFeature Extraction from Speech and Phoneme-recognition Using
Speech is a time varying signal. What makes it more interesting is that the information contained in the signal is very difficult to analyze. Traditional methods of speech analysis use Short Time Fourier Transform and Mel Frequency Cepstral Coefficients (MFCC) to extract the feature out of a speech signal, and the model has been successfully implemented in many speech recognition machines. Thei...
متن کاملWavelet based feature extraction for phoneme recognition
In an effort to provide a more efficient representation of the acoustical speech signal in the pre-classification stage of a speech recognition system, we consider the application of the Best-Basis Algorithm of Coifman and Wickerhauser. This combines the advantages of using a smooth, compactly-supported wavelet basis with an adaptive time-scale analysis dependent on the problem at hand. We star...
متن کاملICA-based feature extraction for phoneme recognition
We propose a new scheme to reduce phase sensitivity in independent component analysis (ICA)-based feature extraction using an analytical description of the ICAadapted basis functions. Furthermore, since the basis functions are not shift invariant, we extend the method to include a spectral-domain ICA stage that removes redundant time shift information. The performance of the new scheme is evalu...
