摘要
Disclosed herein is a system, method and computer-readable medium storing instructions for controlling a computing device according to the method. As an example embodiment, the method uses a speech recognition decoder that operates or uses fixed-point arithmetic. The exemplary method comprises 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. The method may also include computing at the decoder sentence hypothesis probabilities with fixed-point arithmetic as type Q-2e numbers.
