US 2018/0018973 A1 · SPEAKER VERIFICATION

Abstract

Methods, systems, apparatus, including computer programs encoded on computer storage medium, to facilitate language independent-speaker verification. In one aspect, a method includes actions of receiving, by a user device, audio data representing an utterance of a user. Other actions may include providing, to a neural network stored on the user device, input data derived from the audio data and a language identifier. The neural network may be trained using speech data representing speech in different languages or dialects. The method may include additional actions of generating, based on output of the neural network produced in response to receiving the set of input data, a speaker representation and determining, based on the speaker representation and a second representation, that the utterance is an utterance of the user. The method may provide the user with access to the user device based on determining that the utterance is an utterance of the user.

Claims20

Dependent claims

A computer-implemented method comprising:

receiving, by a mobile device that implements a language-independent speaker verification model comprising a neural network that is stored on the mobile device and configured to determine whether received audio data likely includes an utterance of one of multiple language-specific hotwords, (i) particular audio data corresponding to a particular utterance of a user, and (ii) data indicating a particular language spoken by the user;
and
in response to receiving (i) the particular audio data corresponding to a particular utterance of a user, and (ii) the data indicating a particular language spoken by the user, providing, for output, an indication that the language-independent speaker verification model has determined that the particular audio data likely includes the utterance of a hotword designated for the particular language spoken by the user.

A method comprising:

receiving, by a user device, audio data representing an utterance of a user;
providing, to a language independent speaker verification model comprising a neural network stored on the user device, a set of input data derived from the audio data and a language identifier or location identifier associated with the user device, the neural network having parameters trained using speech data representing speech in different languages or dialects;
generating, based on output of the language independent speaker verification model produced in response to receiving the set of input data, a speaker representation indicative of characteristics of the voice of the user;
determining, based on the speaker representation and a second representation, that the utterance is an utterance of the user;
and
providing the user access to the user device based on determining that the utterance is an utterance of the user.

3 more elements

A system comprising:

one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
receiving, by a user device, audio data representing an utterance of a user;
providing, to a language independent speaker verification model comprising a neural network stored on the user device, a set of input data derived from the audio data and a language identifier or location identifier associated with the user device, the neural network having parameters trained using speech data representing speech in different languages or different dialects;
generating, based on output of the language independent speaker verification model produced in response to receiving the set of input data, a speaker representation indicative of characteristics of the voice of the user;
determining, based on the speaker representation and a second representation, that the utterance is an utterance of the user;
and
providing the user access to the user device based on determining that the utterance is an utterance of the user.
