Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes the characteristics of voices uttered with different distance perspectives.
When we use a loud voice in order to speak to those who are at some distance,
the manner of breathing should differ from when we use a normal voice.
This is supposed to bring not only an increase in loudness of speech but a change in voice quality.
First, the voices uttered by the voice actress expressing different distance perspectives were analyzed.
The analysis results showed that (1) the first formant frequency becomes higher, and (2) the spectral tilt becomes flatter, as the distance becomes longer.
Next, the experiment in conversion of distance perspective was carried out.
