  • Publication number: 20170251304
    Abstract: An communication system supports communication paths within an environment by receiving speech signals of a speaker and playing it back for one or more listeners. Signal processing tasks are split into a microphone related part and into a loudspeaker related part. A sound processing system suitable for use in an environment having multiple acoustic zones includes a plurality of microphone communication instances coupled and a plurality of loudspeaker instances.

  • Patent number: 9641934
    Abstract: An In-Car Communication (ICC) system supports the communication paths within a car by receiving the speech signals of a speaking passenger and playing it back for one or more listening passengers. Signal processing tasks are split into a microphone related part and into a loudspeaker related part. A sound processing system suitable for use in a vehicle having multiple acoustic zones includes a plurality of microphone In-Car Communication (Mic-ICC) instances coupled and a plurality of loudspeaker In-Car Communication (Ls-ICC) instances. The system further includes a dynamic audio routing matrix with a controller and coupled to the Mic-ICC instances, a mixer coupled to the plurality of Mic-ICC instances and a distributor coupled to the Ls-ICC instances.

  • Patent number: 9549250
    Abstract: An in-car communication (ICC) system has multiple acoustic zones having varying acoustic environments. At least one input microphone within at least one acoustic zone develops a corresponding microphone signal from one or more system users. At least one loudspeaker within at least one acoustic zone provides acoustic audio to the system users. A wind noise module makes a determination of when wind noise is present in the microphone signal and modifies the microphone signal based on the determination.

  • Publication number: 20170011753
    Abstract: Methods and apparatus for a communication system having microphones and loudspeakers to determine a noise and speech level estimate for a transformed signal, determine a SNR from the noise and speech level estimates, and determine a gain for the transformed signal to achieve a selected SNR range at a given position. In one embodiment, the gain is determined by adapting an actual gain to follow a target gain, wherein the target gain is adjusted to achieve the selected SNR range.

  • Patent number: 9502050
    Abstract: A speech communication system includes a speech service compartment for holding one or more system users. The speech service compartment includes a plurality of acoustic zones having varying acoustic environments. At least one input microphone is located within the speech service compartment, for developing microphone input signals from the one or more system users. At least one loudspeaker is located within the service compartment. An in-car communication (ICC) system receives and processes the microphone input signals, forming loudspeaker output signals that are provided to one or more of the at least one output loudspeakers. The ICC system includes at least one of a speaker dedicated signal processing module and a listener specific signal processing module, that controls the processing of the microphone input signal and/or forming of the loudspeaker output signal based, at least in part, on at least one of an associated acoustic environment(s) and resulting psychoacoustic effect(s).
