Abstract
A method and apparatus for speaker independent real-time affect detection includes generating (205) a sequence of audio frames from a segment of speech, generating (210) a sequence of feature sets by generating a feature set for each frame, and applying (215) the sequence of feature sets to a sequential classifier to determine a most likely affect expressed in the segment of speech.
Claims10
A method for speaker independent real-time affect detection, comprising:
- generating a sequence of audio frames from a segment of speech;
- generating a sequence of feature sets by generating a feature set for each frame;
- and
- applying the sequence of feature sets to a sequential classifier to determine a most likely affect expressed in the segment of speech.
1 more element
An electronic device that detects affects, comprising:
- a frame generator that generates a sequence of digitized audio frames from a segment of speech;
- a feature set generator coupled to the frame generator that generates a sequence of feature sets by generating a feature set for each frame;
- a sequential classifier coupled to the feature set generator for determining a most likely affect expressed in the segment of speech from the sequence of feature sets.
