What does vicPURE voice offer?

AEC

The acoustic echo cancellation is VDA approved and enables full-duplex communication even under difficult conditions

ANR

Automatic noise cancellation eliminates both quasi-stationary and non-stationary interference

Beamforming

Adaptive beamforming supports variable microphone configurations and automatically adjusts to existing environmental conditions

ASL

Automatic source localization detects speech-like sources even in noisy environments and follows the detected source in real time

CUI

The speech interface provides offline speech recognition and speech synthesis and is tuned to the existing algorithms

DM

The dialog manger links the various input modalities and knowledge bases with the customers' application logic.

AM

The integrated audio manager allows flexible connections of a variety of audio sources and sinks

ICC

The In-Car Communication Module secures communication within passenger compartments
