Patent ID: 7366673

Claim:
A method for processing speech audio in a network connected client device comprising: selecting a speech grammar for use in a speech recognition system in the network connected client device; characterizing the selected speech grammar, wherein said characterization comprises determining a size and a complexity of said selected grammar, and wherein a preferred processing location is specified in said selected speech grammar; determining a processing power of said client device and of a remote speech server, a speed of a network connection between said client device and said speech server, and a feedback requirement for said speech recognition system; and, based on the characterization of said selected speech grammar, said determined network connection speed, said determined processing power of the network connected client device and said remote speech server, and said feedback requirements, electing whether to process the entire selected speech grammar in said preferred location or another location different from said preferred location before processing the speech audio, wherein said preferred location specifies the network connected client device or the speech server, wherein if said preferred location specifies said speech server, said client device elects said client device if real-time feedback is required by said speech recognition system and a processing power of said client device is sufficient for said client device to process said selected speech grammar in real-time based on said size and said complexity of said selected grammar, and wherein if said preferred location specifies said client device, said client device elects said remote speech server if a latency in processing said selected speech grammar based on said network speed and said remote speech server processing power is sufficient to meet a feedback requirement of said speech recognition system.
