Advances in Missing Feature Techniques for Robust Large-Vocabulary Continuous Speech Recognition


Missing feature theory (MFT) has demonstrated great potential for improving the noise robustness in speech recognition. MFT was mostly applied in the log-spectral domain since this is also the representation in which the masks have a simple formulation. However, with diagonally structured covariance matrices in the log-spectral domain, recognition… (More)
