Abstract: Techniques for dynamically maintaining speech processing data on a local device for frequently input commands are described. One or more devices receive speech processing data specific to one or more commands associated with system input frequencies satisfying an input frequency threshold. The device(s) then receives input audio corresponding to an utterance and generate input audio data corresponding thereto. The device(s) performs speech recognition processing on input audio data to generate input text data using a portion of the received speech processing data. The device(s) determines a probability score associated with the input text data and determines the probability score satisfies a threshold probability score. The device(s) then performs natural language processing on the input text data to determine the command using a portion of the speech processing data. The device(s) then outputs audio data responsive to the command.

Abstract: Techniques for dynamically maintaining speech processing data on a local device for frequently input commands are described. A system determines a usage history associated with a user profile. The usage history represents at least a first command. The system determines the first command is associated with an input frequency that satisfies an input frequently threshold. The system also determines the first command is missing from first speech processing data stored by a device associated with the user profile. The system then generates second speech processing data specific to the first command and sends the second speech processing data to the device.
