Abstract
Systems and methods for voice authentication are provided. An example method starts with dynamically generating authentication information and a prompt associated therefor. The authentication information is generated to emphasize differences between an authorized user and others. The authentication information may be generated based on at least one of a user profile, an acoustic environment in which a mobile device is located, and a history of interactions with the mobile device. The authentication information may be an answer to a question which the authorized user would uniquely be able to provide, or it may be a distinctive password. The prompt, for the authentication information, is provided to a user attempting to use the mobile device. The method proceeds with capturing an acoustic sound of a speech of the user and detecting the authentication information in the speech. Based on the detection, a confidence score is determined. Based on the confidence score and context, the method performs an authentication of the user or providing the confidence score, the context, and a transcription of the speech to a next stage of authentication.
