SNR is pretty important; often, just as important is a constant audio level, which is why close-talking microphones work so much better than desktop microphones. Frequency response is important, particularly a fairly flat response; a broad response (anything past 12 KHz) is less important. Output impedance isn't terribly important at all (assuming it's matched reasonably well to the audio input).
How does quality of microphone affect speech recognition?

Pregunta
Most sites I've been to clearly say that for speech recognition, higher quality of microphones lead to better results. I have been surfing around for more details, like how do things like the following affect speech recognition -
- Sensitivity
- SNR
- Frequency Responce
- Output Impedence
But I would like to know about how these affect speech in more detail. The SNR makes sense for noise cancellation, but I dont know much about the others.
Some websites that I have checked out -
