    Is the frequency of everyone's voice unique?I couldn't find any article through web about it!

    there is no single frequency in a persons voice. Our larynx are capable of producing any frequency in the audio range ~(20 - 20k) hz. I would guess that each person produces a unique range of subharmonics with any tone. So yes your voice is unique to you.

    There's quite a bit of information at

    http://www.owlinvestigations.com/forensic_articles/aural_spectrographic/fulltext.html

    perhaps even too much.

    I haven't read all of the material in the above URL myself, but I'll give you my understanding of how a voice works and what identifiable features it has. I shouls warn you that I'm not an expert by any means.

    A voice is a low-frequency "buzz" that is shaped by a time-varying filter. The frequency and composition of the "buzz" is not particularly unique, nor is it constant in normal speech. (This frequency controls the pitch of one's voice, which one can vary over a fairly wide range voluntarily).

    What gives a voice its unique quality is the shaping imposed on the underlying "buzz" by the persons body, which acts as a time varying filter. The length and width of the person's trachea, the exact dimensions of their mouth, and other physiological features basically control this filtering action, and are all highly characteristic of the individual.

    Hahaha when I pinch my nose my voice rules! Anyways I was just thinking about voice frequency after getting a response regarding it in my, Why does a fan make my voice sound funny thread...or something like that. Anyways after some quick research I found that there is a wide range of frequencies produced by people. Here is a sweet, and simple article that I just read.

    It seems rather obvious, I mean audio range is kinda what the voice does. I could imagine the ears picking up a bit extra on the extremes but, I'll bet, not a lot.
