Definitions

Eliminates stereo echo of voice prompts or music being played by the car stereo system in each microphone signal. Acoustic echo canceller allow the system to respond to the user’s voice during music playback or barge-in.

A microphone array utilizing a proprietary adaptive beamforming technology that preserves the speech from ambient noise and detects the direction of the voice commands.

Benefits

• Flexible implementation of optimal voice pick up and transmission to the ASR according to the cabin and number of microphones.

• Optimal usage of available resources.

• Portable to all major computational platforms.
