| Abstract(in English) | In highly noise environments, it is very difficult to make speech communication smooth. Thereby, the bone-conducted speech is focused on. However, the intelligibility of the bone-conducted speech relative to the air-conducted speech is low and the bone-conducted speech is sometimes difficult. It was assumed that the causes of reduction in intelligibility of the bone-conducted speech are attenuation of the high frequency part more than 1kHz and difference of amplitude between each phoneme. In this paper, however, we focus on spectral envelope and discuss its effect on intelligibility in the bone-conducted speech through simulation experiments to utilize cepstrum. In addition, we suggest that the fundamental frequencies are common between the air-conducted and bone-conducted speech. |
