| Abstract(in English) | In this paper, acoustic properties and the recognition method of whispered speech are discussed. A whispered speech database that consists of whispered speech, normal speech and their corresponding facial video images of more than 6, 000 sentences from 100 speakers was prepared. The comparison between whispered and normal utterances show that 1)the cepstrum distance between them is 4 dB for voiced and 2 dB for unvoiced phonemes, respectively, 2)the spectral tilt of the whispered speech is less sloped than the normal speech and 3)the frequency of the lower formants(below 1.5kHz)is upper than that of the normal speech. Acoustic models(HMM)trained by the whispered speech database attain an accuracy of 64% in word recognition experiments. This accuracy can be improved to 76% when MLLR adaptation is applied, while the normal speech HMM adapter with the whispered speech attain only 66 %accuracy. |
