Hybrid Client/Server Speech Recognition In A Mobile Device

A computer readable medium having stored therein instructions executable by at least one processor to cause a computing device to perform functions, the functions comprising:

• capturing audio;
• detecting speech in the captured audio;
• in response to detecting speech in the captured audio, forwarding the captured audio to an embedded speech recognizer and a speech client;
• receiving an embedded-recognizer result for the captured audio from the embedded speech recognizer;
• determining whether a network-recognition criterion is met;
• in response to determining that a network-recognition criterion is met, forwarding the captured audio from the speech client to a network speech recognizer;
• receiving a network-recognizer result for the captured audio from the network speech recognizer;
• and
• forwarding a speech-recognition result for the captured audio to at least one application, wherein the speech-recognition result is based on at least one of the embedded-recognizer result and the network-recognizer result.

A computing device, comprising:

• an audio system for capturing audio;
• a speech detector for detecting speech in the captured audio;
• an embedded speech recognizer configured to generate an embedded-recognizer result for the captured audio;
• a speech client configured to forward the captured audio to a network speech recognizer and to receive a network-recognizer result from the network speech recognizer;
• and
• a speech input controller configured to determine whether to forward the embedded-recognizer result or the network-recognizer result to at least one application.
