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


Thank you very much! I will read these publications.

When using voip in office, sometimes other people in the office are talking but with small volume, what I want to do is suppressing this unwanted voice. I think the first step is to identify some features that can distinguish them.

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.
