This application relates to the field of communication technology, and in particular to a message training method and system based on attention mechanism and recurrent neural network. The method includes acquiring audio input data, processing the audio input data sequentially to obtain a high-dimensional time-frequency feature sequence; inputting the high-dimensional time-frequency feature sequence into a convolutional neural network to obtain a semantic feature map; performing parallel heterogeneous dual-branch processing on the semantic feature map, obtaining attention-weighted features through a convolutional attention module and context-aware features through a bidirectional long short-term memory network; using adaptive feature fusion to assign weights and fuse the attention-weighted features and context-aware features to generate a unified feature representation, and mapping it to the probability distribution of the corresponding character at each time step; using connectionist temporal classification to decode the probability sequence and output the decoded character sequence. The method can adapt to different firing habits, has strong anti-interference ability, and achieves high-precision and stable end-to-end decoding.
