Using speech/non-speech detection to bias recognition search on noisy data

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03)., 2003
This paper focuses on the recognition of noisy speech. We show that the decoding of a noisy speech waveform can be facilitated if the recognizer has explicit knowledge of where it should hypothesize speech phones, and where it should map the acoustics to non-speech phones.

Fast segment search for corpus-based speech enhancement based on speech recognition technology

2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014
Corpus-based speech enhancement has received increasing attention recently since it shows high enhancement performance in highly non-stationary noisy environments by precisely modeling the long-term temporal dynamics of speech. However, it has a disadvantage in that the cost is very high for searching the longest matching clean speech segments from a ...
