Abstract
A method and a device perform user authentication of an occupant in a vehicle based on speech recognition. The device includes a memory that stores a reference embedding set including a feature embedding for a registered user's utterance and feature embeddings for synthesis results between the registered user's utterance and a plurality of environmental noises. The device also includes a user interface that receives input audio including utterance of an occupant of the vehicle and noise, and a processor that transforms the input audio to an input embedding and determines whether the occupant is a registered user based on a comparison between the input embedding and the reference embedding set.
Claims17
A device for user authentication of an occupant in a vehicle, the device comprising:
- a memory configured to store a reference embedding set including a feature embedding for a registered user's utterance and feature embeddings for synthesis results between the registered user's utterance and a plurality of environmental noises;
- a user interface configured to receive input audio including an utterance of an occupant of the vehicle and noise;
- and
- a processor configured to transform the input audio to an input embedding, and determine whether the occupant is a registered user based on a comparison between the input embedding and the reference embedding set
- wherein the registered user is registered in an environment in which at least one of a noise level before the registered user's utterance or a noise level after the registered user's utterance is lower than a noise threshold.
A computer-implemented method for user authentication of a vehicle, the computer-implemented method comprising:
- receiving, by a user interface, input audio including an utterance of an occupant of the vehicle and noise;
- transforming, by a processor, the input audio to an input embedding;
- and
- determining, by the processor, whether the occupant is a registered user based on a comparison between the input embedding and a pre-stored reference embedding set, the reference embedding set including a feature embedding for the registered user's utterance and feature embeddings for synthesis results between the registered user's utterance and a plurality of environmental noises;
- wherein the registered user is registered in an environment in which at least one of a noise level before the registered user's utterance or a noise level after the registered user's utterance is lower than a noise threshold.
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
- program instructions that receive input audio including an utterance of an occupant of the vehicle and noise;
- program instructions that transform the input audio to an input embedding;
- and
- program instructions that determine whether the occupant is a registered user based on a comparison between the input embedding and a pre-stored reference embedding set, the reference embedding set including a feature embedding for the registered user's utterance and feature embeddings for synthesis results between the registered user's utterance and a plurality of environmental noises;
- wherein the registered user is registered in an environment in which at least one of a noise level before the registered user's utterance or a noise level after the registered user's utterance is lower than a noise threshold.
