Voice Isolation Technology™

BlueAnt Voice Isolation Technology™

The Z9 uses revolutionary proprietary DSP software known as the
BlueAnt Voice Isolation Technology™ which uses sophisticated techniques to separate
the voice signal from the noise using the dual microphone array of the Z9.
As a result, this technology is effective against noise sources whether they are
stationary, impulsive or even the sound of other voices.

Background Noise Elimination with Zero Voice Distortion

The BlueAnt Z9 separates the desired voice signal from all of the background noise,
resulting in crystal clear conversations in the noisiest environments

Echo Cancellation

In addition to background noise elimination, the Z9 technology provides truly revolutionary echo cancellation performance. Treating acoustic echo as another background noise source. The Z9 eliminates this echo, allowing for true full-duplex operation. Effective at eliminating the acoustically coupled signal that can cause annoying echo in Bluetooth headsets operated at high volume

Improved Automatic Speech Recognition

Automatic speech recognition performance is dramatically improved by the clear voice, free from background noise. This allows the user to have a greater percentage success rate in using voice commands with cell phones.

Using Voice Isolation Technology™ in the BlueAnt Z9

You can switch between two settings of Voice Isolation - STANDARD and MAX.
Voice Isolation Standard for use in normal environments gives you a natural sounding voice removing mild noise.
Voice Isolation Max gives you more intelligible voice in a wide variety of high noise areas.
