Patent number: 9336780Abstract: Method for speaker identification includes detecting a target speaker's utterance locally; extracting features from the detected utterance locally, analyzing the extracted features in the local device to obtain information on the speaker identification and/or encoding the extracted features locally, transmitting the encoded extracted features to a remote server, decoding and analyzing the received extracted features by the server to obtain information on the speaker identification, and transmitting the information on the speaker identification from the server to the location where the speaker's utterance was detected. The method further includes detecting speech activity locally. Extracting features, encoding the extracted features, and/or transmitting the encoded extracted features to the server, are only performed if speech activity above some predetermined threshold is detected.Type: GrantFiled: June 20, 2011Date of Patent: May 10, 2016Assignee: AGNITIO, S.L.Inventors: Luis Buera Rodriguez, Carlos Vaquero Aviles-Casco, Marta Garcia Gomar

Publication number: 20150112682Abstract: The present invention refers to a method for verifying the identity of a speaker based on the speaker's voice comprising the steps of: a) receiving a voice utterance; b) using biometric voice data to verify that the speakers voice corresponds to the speaker the identity of which is to be verified based on the received voice utterance; and c) verifying that the received voice utterance is not falsified, preferably after having verified the speakers voice; d) accepting the speaker's identity to be verified in case that both verification steps give a positive result and not accepting the speaker's identity to be verified if any of the verification steps give a negative result. The invention further refers to a corresponding computer readable medium and a computer.Type: ApplicationFiled: January 5, 2015Publication date: April 23, 2015Inventors: Luis Buera Rodriguez, Marta Garcia Gomar, Marta Sanchez Asenjo, Alberto Martin de los Santos de las Heras, Alfredo Gutierrez, Carlos Vaquero Aviles-Casco, Alfonso Ortega Gimenez
