| Abstract(in English) | In this research, we aim to improve the performance of non-audible murmur (NAM) recognition towards the development of silent speech interfaces. First, we apply a deep learning technique to the acoustic modeling of NAM and develop speaker-dependent acoustic models using speaker adaptive training for a deep neural network (DNN). Moreover, to improve the recognition performance under noisy conditions, we also develop the noise-dependent acoustic models using noisy NAM data generated by superimposing noise signals recorded with NAM microphone. Experimental results show that our developed speaker- and noise-dependent acoustic models are effective for significantly improving NAM recognition performance under both clean and noisy conditions and achieving recognition performance under some noisy conditions comparable to that under the clean condition. |
