Patent ID: 8417185

Claim:
A wireless device for use with a separate processing device that runs speech recognition applications, the wireless device comprising: speech processing circuitry for providing initial speech processing of audio captured from a user and including a frame generator for generating successive frames from digitized audio signals that are reflective of the audio signals captured from the user, the frames representing portions of the digitized audio signals; and autocorrelation circuitry for generating a set of coefficients for each frame, the coefficient set containing information about spectral characteristics of the audio signal portion represented by the frame; processing circuitry configured for transforming the set of coefficients into data in a Bluetooth data packet type instead of a voice packet type for wireless transmission; a Bluetooth transceiver configured for transmitting the set of coefficients as data in the Bluetooth data packet type and configured for using an asynchronous connection-less (ACL) link with a separate processing device for transmitting the set of coefficients to the processing device; wherein the separate processing device utilizes the coefficients for further processing for speech recognition applications.
