Abstract
Techniques for performing spoken language understanding (SLU) processing on a device are described. Example embodiments involve a device determining whether a spoken input corresponds to a supported spoken input class, a supported spoken input with dynamic content class or an unsupported spoken input class. For a spoken input corresponding to the supported spoken input with dynamic content class, the device may determine an entity corresponding to the spoken input from a set of entities, which may be determined based on device context data and/or user profile data. For a spoken input corresponding to the supported spoken input class, the device may determine an intent and entity using stored data. For a spoken input corresponding to the unsupported spoken input class, the device may send the audio data to a system for processing.
