Naw, that won't work Marty, it boils down to being the same
volume slider that I was setting to zero manually

After further testing yesterday I have to agree you are absolutely correct.
Background noise in my office usually never gets worse than what I would call
moderate levels. This is when our shipping manager about 20 feet away starts
packaging orders to go out. The loudest noises actually when he rips the
packing tape from the tape gun. Up to that level I have no problem.

Yesterday I played a recording made in a noisy brokerage stock trading
office. I had the noise coming from left and right at about 95 dB. Even with
three different highly noise canceling microphones, and with the volume
sliders set to zero (they magically set themselves back up to 100 somehow)
WSR became much less accurate.

I have to visit a demonstration by a major manufacturer today in New York
City, but tomorrow I will write up a report for submission to the speech
recognition workgroup at Microsoft. They are very open with me about issues
they are allowed to talk about and I look forward to hearing back from them
and will report here if I'm able to.

Thanks for bringing this issue to the forefront.
