I have tried many microphones over the years to fit my particular needs. My latest acquisition is the Plantronics CS-50, and I am having great success with it. It's range is incredible, and so far, its noise canceling capabilities must be pretty good as the television set does not cause Windows Speech Recognition to shut down randomly like it has always done before. Anyway, this is only secondary to the reason I'm posting this; for the same number of years that I have been looking for the perfect microphone, I have been trying to figure out the proper recording device settings for each microphone I've tried.

I now know that this Plantronics microphone is my best option, but nowhere on the Internet can I find any real information on the best settings for recording devices where speech recognition is concerned. For instance, this microphone has multiple settings for sample rate and bit depth, ranging from one channel, 16 bit, 8000 hz (telephone quality), to two channels, 16 bit, 48000 hz. What I've never understood, and I've never been able to find out, is what is the best choice for speech recognition microphones? Also, under the advanced tab in microphone properties, there is another option called Exclusive Mode (allow applications to take exclusive control of this device & give exclusive mode applications priority). When using a microphone for speech recognition, should one turn these options on, or turn them off?

If anyone has an answer to either of these questions, I would certainly appreciate hearing it. :-)

Apparently, no one understands this issue any better than I do. So now I will impart some interesting observations. I seem to get generally good results no matter what the sample rate is set at, but even more interesting is that I get the best accuracy when the WSR Toolkit serial to noise ratio and input volume are both set to zero. This makes absolutely no sense to me, so I was curious to know whether anyone here understands the reason for this?

The most probable answer is the volume level of the recorder is high. As for audio settings, use the default.

Hey, Marty, great to still see you here! :-)
I'm not sure that I understand what you mean by the volume level of the recorder… What recorder? Do you mean the Plantronics headset/microphone?

In the first posting in this thread you said:
"nowhere on the Internet can I find any real information on the best settings for recording devices where speech recognition is concerned." Since a microphone is an audio input device, I assumed you meant a digital voice recorder which would be used to transcribe to text.

But, Marty, in Windows 7 microphones are not listed as audio input devices, but as recording devices. That's what I was referring to, anyway. Sorry for the confusion. Smile

Thanks for the clarification. Sorry for not thinking it through.
