"BlueAnt showed off three new Bluetooth-enabled products—two of which offer voice recognition—that the company had originally announced back in January at CES 2008. Its V1 Voice Controlled Headset features Sensory, Inc.'s BlueGenie Voice Interface, which eliminates having to memorize complicated sequences of button pushes. Instead, you talk to the device and (in theory) it tries to figure out what you want it to do. The V1 also includes dual microphones along with Voice Isolation Technology for more effective noise cancellation, wind noise reduction, and better sound quality.
The second model, the BlueAnt Supertooth 3, is an upgrade to last year's Supertooth Light hands-free device. Like the older model, it either clips to your car's sun visor or sits on your desk. It builds on the former model's text-to-speech technology, which announces incoming callers names and caller ID information. The Supertooth 3 lets you activate voice dialing, answer calls, reject calls, and redial all with just the sound of your voice, and also includes a DSP chip for noise cancellation."
