Patent ID: 7349844

Claim:
A processor system for speech recognition processing of an audio signal, the processor system comprising: a) front-end processing means for preprocessing of the audio signal and for generating an output of first data, b) core processing means for performing speech recognition processing on the first data, c) dual access storage means for buffering of the first data, the dual access storage means being coupled between the front-end processing means and the core processing means, d) means for invoking the core processing means for performing the speech recognition processing after a time interval following a start of the preprocessing by the front-end processing means, e) means for stopping the execution of the speech recognition processing by the core processing means when the amount of first data stored in the dual access storage means falls below a predefined threshold level, f) means for triggering the execution of the speech recognition processing by the core processing means when the dual access storage means is refilled by first data to a level equal to or above the threshold level.
