Product Description

The small SuperBeam microphone is attached to your monitor/laptop screen, pointing towards you. It is then plugged into the supplied Andrea digital USB adapter which is in turn connected to the USB port of your computer. You can now dictate totally hands free! With sufficient training ( it take a little longer than a headset microphone) we have found these to be as accurate a a high quality headset when using Dragon.

This Andrea Microphone has a higher Nuance/Dragon accuracy rating than the Voice Tracker by Acoustic Magic.

Features
• The Andrea Array is a far-field, 2-microphone array with stereo output.
• Offers the highest quality and performance of a low cost upgrade over a single element microphone.
• Small size for unobtrusive mounting on a monitor or laptop.
• Specifically designed for use with Andrea DSDA®, and PureAudio® noise reduction software running on the host processor to enable un tethered:
• Continuous Speech Recognition
• Command and Control
• Voice over IP Internet Telephony
• Andrea’s DSDA® and PureAudio® noise canceling algorithms allow for superior audio quality by
canceling out background noise resulting in increased intelligibility of communications.
