Many studies have assessed talker sound location in
hands-free tele-conferences systems.
However, no study has examined auditory perception
with regard to speech-direction of the talker.
The purpose of this study is to identify the perceptional cues of the
speech-direction with no visual reference.
The auditory perception of speech-direction might be due to the
variation of transfer function from the talker's mouth to the center of
listener's head and the Interaural Level Difference(ILD) of the listener.
The transfer function and ILD are theoretically calculated and measured,
and two subjective assessment tests are carried out.
The results clarify that ILD is more important than the variation of
transfer function, and that ILD in the frontal vicinity of the talker yields good perception of speech-direction. |
