VOICE APPLICATION ARCHITECTURE

摘要

A voice-based system may comprise a local speech interface device and a remote control service. A user may interact with the system using speech to obtain services and perform functions. The system may allow a user to install applications to provide enhanced or customized functionality. Such applications may be installed on either the speech interface device or the control service. The control service receives user speech and determines user intent based on the speech. If an application installed on the control service can respond to the intent, that application is called. Otherwise, the intent is provided to the speech interface device which responds by invoking one of its applications to respond to the intent.

1. A system comprising:
one or more server computers; one or more server applications that have been selected and enabled by a user for execution on the one or more server computers, wherein the one or more selected and enabled server applications operate in conjunction with a speech interface device located in premises of the user to provide services for the user; a speech processing component configured to receive first and second utterances from the speech interface device, wherein the first and second utterances express first and second user intents, respectively, the speech processing component being further configured to perform automatic speech recognition and natural language understanding on the first and second utterances to determine the first and second user intents; an intent router configured to perform acts comprising:
identifying a server application of the one or more server applications corresponding to the first user intent;invoking the identified server application to perform a first action corresponding to the first user intent; andproviding an indication of the second user intent to the speech interface device, wherein the speech interface device is responsive to the second user intent to perform a second action corresponding to the second user intent.
