Patent number: 11545155Abstract: 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: July 2, 2020Date of Patent: January 3, 2023Assignee: Cirrus Logic, Inc.Inventor: Marta Garcia Gomar

Patent number: 10877727Abstract: A received signal represents a user's speech. A first speaker recognition process is performed on a first portion of the received signal, to obtain a first output result. A second speaker recognition process is performed on a second portion of the received signal that is different from the first portion of the received signal, to obtain a second output result. The second speaker recognition process is different from the first speaker recognition process. The first and second output results are combined to obtain a combined output result indicating a likelihood that the user is a registered user.Type: GrantFiled: June 28, 2019Date of Patent: December 29, 2020Assignee: Cirrus Logic, Inc.Inventors: Carlos Vaquero Avilés-Casco, Marta García Gomar, David Martínez González

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
