Patent number: 9741346Abstract: A method for estimating the reliability of a result of a speaker recognition system concerning a testing audio and a speaker model, which is based on one, two, three or more model audios, the method using a Bayesian Network to estimate whether the result is reliable. In estimating the reliability of the result of the speaker recognition system one, two, three, four or more than four quality measures of the testing audio and one, two, three, four or more than four quality measures of the model audio(s) are used.Type: GrantFiled: April 23, 2014Date of Patent: August 22, 2017Assignee: AGNITIO, S.L.Inventors: Carlos Vaquero Avilés-Casco, Luis Buera Rodriguez, Jesús Antonio Villalba López

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: 20150206538Abstract: A tamper-resistant element for use in speaker recognition, the tamper-resistant element being adapted for storing data representing speaker information based on speaker recognition enrollment data and for checking whether information based on a speaker recognition testing signal matches the speaker information. The tamper-resistant element is also adapted for carrying out a data integrity check. Also, a system including such a tamper-resistant element and method for speaker recognition.Type: ApplicationFiled: May 19, 2014Publication date: July 23, 2015Applicant: AGNITIO, S.L.Inventors: Carlos Vaquero Aviles-Casco, Luis Buera Rodriguez, Marta Garcia Gomar

Patent number: 9043207Abstract: The present invention relates to a method for speaker recognition, comprising the steps of obtaining and storing speaker information for at least one target speaker; obtaining a plurality of speech samples from a plurality of telephone calls from at least one unknown speaker; classifying the speech samples according to the at least one unknown speaker thereby providing speaker-dependent classes of speech samples; extracting speaker information for the speech samples of each of the speaker-dependent classes of speech samples; combining the extracted speaker information for each of the speaker-dependent classes of speech samples; comparing the combined extracted speaker information for each of the speaker-dependent classes of speech samples with the stored speaker information for the at least one target speaker to obtain at least one comparison result; and determining whether one of the at least one unknown speakers is identical with the at least one target speaker based on the at least one comparison result.Type: GrantFiled: November 12, 2009Date of Patent: May 26, 2015Assignee: Agnitio S.L.Inventors: Johan Nikolaas Langehoven Brummer, Luis Buera Rodriguez, Marta Garcia Gomar

Patent number: 9042867Abstract: A speaker recognition system for authenticating a mobile device user includes an enrollment and learning software module, a voice biometric authentication software module, and a secure software application. Upon request by a user of the mobile device, the enrollment and learning software module displays text prompts to the user, receives speech utterances from the user, and produces a voice biometric print. The enrollment and training software module determines when a voice biometric print has met at least a quality threshold before storing it on the mobile device. The secure software application prompts a user requiring authentication to repeat an utterance based at least on an attribute of a selected voice biometric print, receives a corresponding utterance, requests the voice biometric authentication software module to verify the identity of the second user using the utterance, and, if the user is authenticated, imports the voice biometric print.Type: GrantFiled: December 12, 2012Date of Patent: May 26, 2015Assignee: Agnitio S.L.Inventor: Marta Garcia Gomar

Publication number: 20110071831Abstract: The present invention refers to a method for localizing a person comprising the steps carried out in a computing system (1): determining (20) the localization of a telecommunication means (3, 6, 8) or determining a telecommunication means (3, 6, 8) at a specific location; this can be implemented using ANI or calling number received and a database to look up address of a fixed telephone, for a cellular device, cell-ID or triangulation can be used; receiving (21) a voice utterance of a person by the telecommunications means; and verifying (22) the identity of that person based on the received voice utterance using biometric voice data (speech, speaker recognition). Further the invention relates to a corresponding system and computer readable medium.Type: ApplicationFiled: May 9, 2008Publication date: March 24, 2011Applicant: AGNITIO, S.L.Inventors: Marta Garcia Gomar, Marta Sanchez Asenjo
