1. A machine executable program for assisting a computing system to effectuate distributed voice query recognition comprising:

  • a first audio signal receiving routine for receiving user speech utterance signals representing speech utterances to be recognized, said speech utterances including sentences comprised of one or more words; and

    a first signal processing routine adapted to generate representative speech data values from said speech utterance signals, said representative speech data values being characterized by a first data content that is substantially inadequate by itself for permitting recognition of words articulated in said speech utterance; and

    a formatting routine for rendering said representative speech data values into a transmission format suitable for transmission over a communications channel to a second processing routine executing on a separate computing system wherein said representative speech data values are transmitted continuously during said speech utterances within streaming packets and without waiting for silence to be detected and/or said speech utterances to be completed; and

    wherein said first data content in said representative speech data values is used by said second processing routine to compute additional data content that when combined with said first data content is sufficient for a speech recognition routine to complete recognition of words articulated in said speech utterance at said separate computing system and further wherein an amount of said first data content transmitted is configured and can be varied for said speech utterances based on signal processing capabilities of the computing system and/or transmission characteristics of said communications channel.
