  • Method for the location of a speaker and the acquisition of a voice message, and related system
    Patent number: 5465302
    Abstract: A system for the detection and location of acoustic signals which can be used, for example, for the acquisition of voice messages or the like, in environments in which noises, echoes and reverberations are present. The system employs an array of microphones and is based on the Fourier antitransform calculus of only the information of phases of the normalised cross power spectrum of pairs of signals acquired from the microphones in the array. The system also enables an acoustic message cleared of the undesired components which are due to noises, echoes, etc to be reconstructed.
