Abstract
A distributed voice user interface system includes a local device which receives speech input issued from a user. Such speech input may specify a command or a request by the user. The local device performs preliminary processing of the speech input and determines whether it is able to respond to the command or request by itself. If not, the local device initiates communication with a remote system for further processing of the speech input.

14. A distributed voice user interface system comprising:
-
a local device operable to scan speech input issued by a user for a keyword, and to initiate communication with a remote system when the keyword is detected; and
the remote system operable to receive the speech input from the local device and to recognize words in the speech input.

23. A local device comprising:
-
an input device operable to receive speech input issued from a user, the speech input specifying a command or a request by the user; and
a processing component coupled to the input device and operable to perform preliminary processing of the speech input, to determine whether the local device is by itself able to respond to the command or request specified in the speech input, and to initiate communication with a remote system for further processing of the speech input if the local device by itself is not able to respond to the command or request.

29. A remote system comprising:
-
a transceiver operable to receive speech input issued by a user, the speech input preliminarily processed and forwarded by a local device; and
a processing component coupled to the transceiver and operable to recognize words in the speech input.

-
35. A method comprising:
-
scanning speech input issued by a user at a local device for a keyword;
initiating a connection between the local device and a remote system when the keyword is detected; and
passing the speech input from the local device to the remote system for interpretation.
