The ICC (In Car Communication) is a 3rd party product by Cerence\u2122.<\/span><\/p>\n

The communication between passengers in a vehicle \u2013 especially between front and rear passengers \u2013 is often difficult due to the high acoustic loss of the speech level and the background noise superimposing the speech signal. Therefore, speakers must speak louder than normal, which makes longer conversations stressful, and if the driver turns his head even driving safety is impaired. The In-Car Communication audio object helps to overcome these problems by improving the intelligibility of conversations between front and rear passengers in a vehicle. The ICC system picks up the speech signal of the seat dedicated microphones and distributes them via the sound system. Signals from the front passengers are played back via the rear loudspeakers; signals from the rear speakers via the front loudspeakers.<\/span><\/p>\n

The signal processing algorithms of the ICC attenuate background noise and ensure stable operation of the system by suppressing feedback echoes and howling. This is accomplished by noise and feedback suppression algorithms optimized for the low latency requirements of the ICC system. An automatic gain control compensates for varying speech levels of different speakers, while an adaptive level control adjusts the system gain to the current background noise level. This ensures an unobtrusive operation of the system while providing always the required speech gain. The user can select between different gain curves to adjust the ICC system to his needs. The overall system gain is limited to guarantee system stability and the system is automatically deactivated if the entertainment level exceeds a predefined level using an entertainment reference channel. Distortion of the audio signal at high playback levels may be avoided.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
