Multi-model approach for noisy speech recognition
Cuntai Guan, S.H. Leung, Wing-Hong Lau · Electronics Letters · 1998
A multi-model approach for noisy speech recognition is proposed. This approach comprises an SVD-based preprocessing front-end, and a multi-model HMM recognition structure. It can provide a high recognition rate over a large range of SNRs for speech recognition in wide-band additive noise.
