Abstract
A speech interface device is configured to receive response data from a remote speech processing system for responding to user speech. This response data may be enhanced with information such as a remote ASR result(s) and a remote NLU result(s). The response data from the remote speech processing system may include one or more cacheable status indicators associated with the NLU result(s) and/or remote directive data, which indicate whether the remote NLU result(s) and/or the remote directive data are individually cacheable. A caching component of the speech interface device allows for caching at least some of this cacheable remote speech processing information, and using the cached information locally on the speech interface device when responding to user speech in the future. This allows for responding to user speech, even when the speech interface device is unable to communicate with a remote speech processing system over a wide area network.
