Abstract

The invention discloses a training sample selection method and device for a speech recognition model, and a medium, and the method comprises the steps: obtaining a correct pronunciation training sample of to-be-recognized speech; performing similar character expansion on the Chinese characters in the to-be-recognized speech; constructing and forming a fault-tolerant training sample by utilizing the expanded similar characters; and fusing the correct pronunciation training sample and the fault-tolerant training sample into a model training sample for training a speech recognition model. According to the method, pronunciation fault-tolerant processing is carried out on the training sample, so that the fault tolerance of a speech recognition system is improved, the purpose that correct candidate words can be provided by an input method even under the condition of pronunciation errors is achieved, and the accuracy and practicability of speech input are improved.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a method, device and medium for selecting training samples of a speech recognition model. Background technique [0002] With the rapid development of speech recognition technology, intelligent voice input method is gradually becoming a common choice for text entry, and is increasingly used in many scenarios in different industries. The intelligent speech input method takes speech recognition technology as the core, and mainly includes feature extraction, acoustic model, language model, dictionary and decoding. By extracting the acoustic features of the speech data to be recognized, it is decoded into a phoneme array based on the acoustic model. Using the dictionary Corresponds to the text output by the language model. This strategy is based and premised on the correct pronunciation of Chinese characters. If the pronunciation is wrong, it is difficult to o...
