1. A method of processing data associated with speech processing, the method using a speech recognition decoder using fixed-point arithmetic, the method comprising: representing arc costs associated with at least one finite-state transducer (FST) in fixed-point; representing parameters associated with a hidden Markov model (HMM in fixed-point; and processing speech data in the speech recognition decoder using fixed-point arithmetic for the fixed-point FST arc costs and the fixed-point HMM parameters.
