Patent ID: 7231350

Claim:
A method for speaker verification, comprising: obtaining at least one set of test sentences by the speaker using a microphone for acoustic data collection and a glottal electromagnetic micropower sensor for electromagnetic data collection, said electromagnetic data collection related to the motions of the speaker's tracheal and glottal tissues during speech production; creating a plurality of speaker verification parameters by extracting parameters from said set of test sentences by the speaker; collecting a plurality of data from the speaker using a microphone for acoustic data collection and a glottal electromagnetic micropower sensor for electromagnetic data collection, said electromagnetic data collection related to the motions of the speaker's tracheal and glottal tissues during speech production; using said plurality of data to create a plurality of parameters, comprising a glottal shape parameter (GSP) derived from sensing motion of the tracheal and glottal tissues, said parameters created by generating multiple feature vectors; and comparing said speaker verification parameters with said parameters for speaker verification.
