Abstract
Techniques for determining and using relevant prosody information for spoken language understanding (SLU) processing are described. In some embodiments, a system determines local prosody data for individual audio frames of input audio data representing a spoken input. The system also determines global prosody data based on the entire spoken input. A portion of the local prosody data is determined to be relevant for a respective audio frame. A portion of the global prosody data is determined to relevant for the spoken input. The relevant portions are used to determine at least an intent corresponding to the spoken input. Audio features corresponding to the input audio data may be used to determine relevant portions of the prosody data.
