Abstract
A client device incorporates partial speech recognition for recognizing a spoken query by a user. The full recognition process is distributed over a client/server architecture, so that the amount of partial recognition signal processing tasks can be allocated on a dynamic basis based on processing resources, channel conditions, etc. Partially processed speech data from the client device can be streamed to a server for a real-time response. Additional natural language processing operations can also be performed to implement sentence recognition functionality.
