Hi All,
I'm starting on this topic for my thesis and just wanting to get your views/opinions/suggestions to it.
Objective
Basically what I aim to acheive is to locate the position of a speaker within a room (from his speech).
Approach
From what I've read so far, my proposed method of approach is by using microphone arrays. Since a simple array would be able to estimate the
direction of a speech source, I was thinking that if i could get multiple microphone arrays located along the walls of the room, then, by triangulation (finding the intersection of each beam of the microphone array), I would then get the location of the speaker.
Improvement
If that is all done, I would then implement some kind of "sensor localization" thing, so as to enable users to arbitarily place each microphone arrays around the room and the computer can then automatically know the locations of each of these microphone arrays.
This seems to be a tough DSP topic, and my DSP knowledge is pretty limited (only one basic DSP course so far). I am not aiming to develop a new localization algorithm, but just to implement one of it (which would work well in my condition).
Any ideas/feedback on this? Thanks a great bunch~
