The xTag wireless microphone's wide band audio combined with HIPAA compliance security [128-bit encryption], complements the Dragon NaturallySpeaking Medical dictation software, which is the most widely used and successful general-purpose speech-enabled clinical documentation solution in the healthcare industry. Now, medical personnel do not need to be tethered to a computer as the xTag wireless microphone allows for natural mobility and is rechargeable -- eliminating the need to wear a headset or a bulky transmitter.
My experience with using the Nuance Dragon NaturallySpeaking software has been with a headset and a boom mike. If I recall correctly, the manual said that it is important to keep the mike in the same position for good results. The photos on their Web site show folks with this mike clipped to their shirt pocket. If it produces transcribed documents that are just as accurate, this will be a big jump up in convenience.
