Re: what's the difference between the voice of two people?

[Etienne Gaudrain <e.p.c.gaudrain@xxxxxxx>]

Hi Siping,

There's many cues. We studied two obvious that are directly related to the anatomy of the speaker: glottal-pulse rate and vocal-tract length. There's many papers on the topic from Patterson's lab (http://www.pdn.cam.ac.uk/groups/cnbh/research/publications/). One that may directly answer your question is:

Gaudrain, Etienne, S Li, VS Ban, and RD Patterson. “The Role of Glottal Pulse Rate and Vocal Tract Length in the Perception of Speaker Identity.” Interspeech 2009: 10th Annual Conference of the International Speech Communication Association 1-5 (2009): 152–155.

Regards,
-Etienne
