Hi,
I am recently trying to make my tablet react to voice commands. Primarily, I intend to use a similar stuff for my personal home entertainment system (suse 11 linux box).

After all the works, now, I am stuck with a basic problem... While playing music in speakers, the noise is totally corrupting the input speech. I am clueless of how to deal with that. Had anyone tried a similar stuff? If I keep the microphone close to the mouth, it is quite good. But, I want it to react in a range of 1 meter where my coffee table is. (my speakers are 3 meters away)

Thanks in advance for ur suggestions.

I've thought about this before and the only way I could figure out to isolate it was to use a headset with a microphone. the problem is all voice recognition software needs to be able to isolate your voice from everything else. once there is some background noise it gets totally confused.

Oh okay. So, I guess voice activation can be just for silent operations. In that case, what is your opinion on how to setup a home theater system? I dont know if it is worth it to build it yourself, or buy a PS3 and install linux in it. You get a wireless game controller that can be used as a remote.

I use my iPod touch as my remote for my home theater. it's wifi so there is no line of sight problems. it's touchscreen so you just touch the buttons on the screen like a remote and it lights up so you can use it in the dark. it just loads a webpage in safari that's hosted on apache on my media pc.
