Wireless device to access network-based voice-activated services using distributed speech recognition

A wireless telecommunication device comprising:

• an audio input device to sense a speech utterance;
• an automatic speech recognition engine responsive to the audio input device to perform a local attempt to recognize the speech utterance and to retrieve at least one local recognition result based on the local attempt;
• a speech features extraction module responsive to the audio input device to compress the speech utterance into compressed data;
• a data sync agent to communicate the compressed data to a remote system and to receive at least one remote recognition result from the remote system, the at least one remote recognition result based on a first remote attempt to recognize the speech utterance by the remote system based on the compressed data using a personal directory specific to the mobile telecommunication device, the at least one remote recognition result further based on a second remote attempt to recognize the speech utterance by the remote system based on the compressed data using a group directory for a group of which the mobile telecommunication device is a member;
• and
• a session manager to determine a final recognition result set based on the at least one local recognition result and the at least one remote recognition result.
