| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper presents experimental evaluations of statistical voice conversion from artificial speech spoken by a laryngectomee using some external sound source units. The laryngectomee uses three kinds of the external sound source units; 1)~a sound source unit that generates quite small source signals that cannot be heard by listeners; 2)~a conventional electrolarynx that generates signals with monotone \(F_0\); and 3)~an electrolarynx using an air-pressure sensor that enables the laryngectomee to modulate the \(F_0\) of the sound source signal using the air-pressure output from his/her tracheostoma. The generated artificial speech is detected with a headset microphone or Non-audible murmur microphone, and then, it is converted into whispered voice or normal speech uttered by a nonlaryngectomee. The experimental results demonstrate that 1)~the use of the air-pressure sensor is effective to improve the voice conversion accuracy, 2)~the modulated \(F_0\) using an air-pressure sensor is less effective in \(F_0\) estimation, but it doesn't cause any significant degradation of the voice conversion accuracy, and 3)~voice conversion yields significant improvements in naturalness so that the converted speech is much more preferred to the original artificial speech by listeners. |
