摘要
A method for constructing a speech decoding network in digit speech recognition. The method comprises acquiring training data obtained by means of digit speech recording, wherein the training data comprises a plurality of speech segments, with each speech segment containing pieces of speech of a plurality of digits (110); performing acoustic feature extraction on the training data to obtain a feature sequence corresponding to each speech segment (130); according to the feature sequence and a phone corresponding to a digit in the training data, performing, starting with a mono-phone acoustic model, progressive training to obtain an acoustic model (150); and acquiring a language model, and constructing, by means of the language model and the acoustic model obtained through training, a speech decoding network (170).
