摘要： Disclosed herein are systems, methods, and non-transitory computer-readable storage media relating to speaker verification. In one aspect, a system receives a first user identity from a second user, and, based on the identity, accesses voice characteristics. The system randomly generates a challenge sentence according to a rule and/or grammar, based on the voice characteristics, and prompts the second user to speak the challenge sentence. The system verifies that the second user is the first user if the spoken challenge sentence matches the voice characteristics. In an enrollment aspect, the system constructs an enrollment phrase that covers a minimum threshold of unique speech sounds based on speaker-distinctive phonemes, phoneme clusters, and prosody. Then user utters the enrollment phrase and extracts voice characteristics for the user from the uttered enrollment phrase. The system generates a user profile, based on the voice characteristics, for generating random challenge sentences according to a grammar.

摘要： Devices, systems, methods, media, and programs for detecting an emotional state change in an audio signal are provided. A number of segments of the audio signal are analyzed based on separate lexical and acoustic evaluations, and, for each segment, an emotional state and a confidence score of the emotional state are determined. A current emotional state of the audio signal is tracked for each of the number of segments. For a particular segment, it is determined whether the current emotional state of the audio signal changes to another emotional state based on the emotional state and a comparison of the confidence score of the particular segment to a predetermined threshold.
