Voice specific mic

[IanKay]

Hello

I was wondering if someone could help me. I am developing some software that is voice activated. I want to be able to setup a mic which will be able to hear me anywhere in a room. (typical house sized rooms)

My problem is I know nothing about mics.. I'm guessing it would need some sort of background noise cancellation? but what sort of attributes should I be looking for? I have seen things like "frequency range" and "output impedance" however I do not know what these means or what values would be good/bad for what I'm trying to accomplish.

If anyone could offer some advice I would be very grateful!

Thanks

Omni pattern mic, the other features would show up in the channel strip or pre amp or other outboard gear.
I am an "Old Schooler" and use outboard stuff.
The Safe Sound P1 has an expander and a compressor and a limiter. These features, when applied correctly, limit unwanted noise, compress the signal and limit the amount of signal getting through, respectively.
Might be more than you need.
You are going to have trouble with "voice actrivated" stuff if there are any other voices (i.e.TV, Radio, etc) as the software will probably recognize them too.
The Mic should be an Omni pattern mic and there are many of those out there.

Omni headset mic.

This should be interesting. Can voice recognition resolve out of a signal with lots of early reflection? Noise reduction, looking at level difference unless you're close to the mic, or louder (at the mic location) would it even help?

I'm thinking maybe a PZM on the ceiling is close as you'd get to max clean direct first arrival. (You can get pretty much the same with an omni strapped to the surface.

Something like this is more difficult than you might think... there aren't really any mics that act exactly like the human ear.

Sennheiser makes tons of mics in every flavor, and for decades their mics have been extremely clear. They seem to have something figured out in that area, so it might be worth looking at some Sennheisers.

The answer depends on what you intend to plug the mic into, what you intend to use the recording for, how much you are willing to spend, and how much background noise there already is in the room. Answer these questions, and our answers will become more useful.-Richie
