Rob, >>>>>>>>>>>>>>>>>>>>>>>> Martin's current recommendation for a good microphone is the Parrott TalkPro Xpress, which also requires a USB converter (either the Andrea USB pod or the Griffin iMic seem to work). Right out of the box, accuracy was notably improved over either the Plantronics or the Andrea microphones. My thanks once again to Martin for an excellent recommendation. >>>>>>>>>>>>>>>>>>>>>>>> Thank you for your excellent evaluation of the various microphones and how they work with ViaVoice and iListen. However, let us give credit where credit is due. It was Patrick Henebry who put me on to using the VXI TalkPro Xpress with the Andrea pod for the Mac speech recognition softwares. It really does take many people to come up with what is best for this emerging software. Martin Markoe, eMicrophones, Inc.
