Title: METHOD AND DEVICE TO DETERMINE SOUND SOURCE DIRECTION AND SPEECH QUALITY ENHANCEMENT USING SMALL MICROPHONE ARRAYS
Abstract:
Herein provided is a method and system to determine a sound source direction using a microphone array comprising at least four microphones by analysis of the complex coherence between at least two microphones. The method includes determining the relative angle of incidence of the sound source and communicating directional data to a secondary device, and adjusting at least one parameter of the device in view of the directional data. Other embodiments are disclosed.
