Abstract: A system and method automates the tuning of one or more hands-free library parameters. The system and method plays one or more test signals that vary in frequency and in amplitude out of a hands-free system under test or the hands-free tuning system and records the responses of a hands-free tuning system or hands-free tuning system at a microphone of the hands-free tuning system and a microphone of the hands-free system under test. The system and method measures the sound generation and sound pickup characteristics of the hands-free system under test or the hands-free system with respect to the one or more of the test signals and one or more of the microphone signals. The system and method calculates tunable parameters. The system and method updates a hands-free system library with the calculated plurality of tunable parameters.

Abstract: Vehicle communication systems and methods of operating the same. The vehicle communication system includes one or more microphones and one or more loudspeakers positioned about a vehicle. The system includes processor executable instructions for determining that the vehicle is operating in an emergency mode and, in response, activating a first microphone and a first loudspeaker for enabling communication between a first acoustic zone within the vehicle and a second acoustic zone exterior to the vehicle. The system may detect, from one of the first acoustic zone and the second acoustic zone, a first acoustic input and generate a second signal from the detected first acoustic input. The system may transmit the second signal to the first loudspeaker for producing sound waves that are audible in the other of the first acoustic zone and the second acoustic zone.

Abstract: An audio or speech enhancement system for a vehicle includes a location-determining subsystem configured to determine a first location of the vehicle and to generate location data representing the first location of the vehicle and an audio/speech-enhancement processor for processing an audio/speech signal wherein the processor is communicatively coupled to the location-determining subsystem for receiving the location data. The processor is configured to predict expected noise at a second location corresponding to a predicted location of the vehicle. The processor is further configured to suppress at least some of the expected noise when the vehicle is at the second location to thereby enhance the audio/speech signal.
