Abstract
Techniques for enabling a device to send to a speech processing server further input audio data following a completed utterance dialog to prevent the need for subsequent keywords to be spoken to invoke subsequent commands are described. A system receives input audio data corresponding to an utterance from a device upon the device detecting speech corresponding to a keyword. The system performs speech processing on the input audio data to determine a command. The system determines output data responsive to the command and sends same to the device, thus completing operations regarding the utterance. The system may also send an instruction to the device to: send to the system further input audio data corresponding to further input audio without the device first detecting a wake command.
