Configurable speech recognition system using multiple recognizers

摘要

Techniques for combining the results of multiple recognizers in a distributed speech recognition architecture. Speech data input to a client device is encoded and processed both locally and remotely by different recognizers configured to be proficient at different speech recognition tasks. The client/server architecture is configurable to enable network providers to specify a policy directed to a trade-off between reducing recognition latency perceived by a user and usage of network resources. The results of the local and remote speech recognition engines are combined based, at least in part, on logic stored by one or more components of the client/server architecture. An indication of the availability of the remote speech recognition to perform speech recognition at a point in time may be provided to a user of the client device via a user interface of the client device.

主权项

1. A client device for use in a client/server speech recognition system comprising the client device and a server device, wherein the server device includes a remote speech recognizer remote from the client device, the client device comprising:
a user interface, the user interface comprising an input interface configured to receive input audio comprising speech, wherein the user interface is further configured to support interacting with a user using any of a plurality of different interaction techniques; and at least one processor programmed to:
determine an availability status, at a point in time, of the remote speech recognizer for performing speech recognition on input audio received via the input interface; andprovide via the user interface, an indication of the availability status, wherein providing the indication of the availability status comprises:
selecting one of the plurality of different interaction techniques based, at least in part, on the availability status; andproviding the indication of the availability status using the selected one of the plurality of different interaction techniques.
