中文摘要we investigate the use of independent component analysis (ica) for speech feature extraction in digits speech recognition systems. we observe that this may be true for recognition tasks based on geometrical learning with little training data. in contrast to image processing, phase information is not essential for digits speech recognition. we therefore propose a new scheme that shows how the phase sensitivity can be removed by using an analytical description of the ica-adapted basis functions. furthermore, since the basis functions are not shift invariant, we extend the method to include a frequency-based ica stage that removes redundant time shift information. the digits speech recognition results show promising accuracy. experiments show that the method based on ica and geometrical learning outperforms hmm in a different number of training samples.
