[MV] Microphones

[Joseph Senecal]

Chris,

As I understand it, Bluetooth headsets have a lower sample rate than  
is needed for dictation applications, and in addition they compress  
the signal using a lossy compression algorithm. This compression  
throws out information that is used by dictation applications in order  
to recognize speech. The problem is that dictation software does not  
listen the same way we do, so different components of the sound waves  
are important. The Jawbone Bluetooth headset is probably particularly  
bad in this regard, it's noise cancellation feature distorts the  
user's voice to the point that I can hear the difference (based on the  
samples posted on the Jawbone site).

The short answer is that very few wireless microphones work with  
dictation. I think I have seen some postings of one or two wireless  
microphones (not Bluetooth) that could work with dictation software,  
but I don't remember the specifics.

I also am using a Plantronics DSP-300 that I bought for iListen, along  
with many other microphones I bought for iListen (some supported, some  
not). I haven't tried all of them with Dictate yet, but those I have  
tried have worked just fine.

PS: I dictated this message using a Plantronics microphone,  
unfortunately I don't know the model number of this one :-)
