David, >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> there seems to be no reference to "theBoom" (http://www.theboom.com), a noise cancelling boom mike that claims much better performance than most n.c. mikes. Has anyone had personal experience with the device? My office is pretty noisy with a couple of old workstations which have really loud fans. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> That is a mobile phone cordless phone headset. It's highly unlikely that it will work well for speech recognition. There are a number of microphones that are known to work well in your type of situation. Inexpensive ones include headsets like the Andrea ANC headsets and VXI TalkPro models. For iListen the TalkPro Xpress and an Andrea USB sound pod are highly recommended. If you want the very best and they're willing to pay for it look at the Sennheiser MD431II with the Andrea USB sound pod. Martin Markoe, eMicrophones, Inc.
