Real-time analysis of linguistic logic during communication through intelligent speech recognition is of profound significance for its global promotion. This article delves into the intricacies of linguistic structure and investigates subject recognition in spoken Japanese, employing deep learning methods. Firstly, we dissect the subjects within Japanese logic, categorizing them into four distinct groups for subsequent classification and labeling. Secondly, this study employs Mel-frequency cepstral coefficients (MFCC) features to extract speech signal attributes, incorporating an attention-based bidirectional long short-term memory (BiLSTM) network for feature fusion to establish a robust foundation for high-precision classification. Lastly, an activation function is employed to execute subject classification in spoken Japanese, yielding a recognition accuracy of 96.1%. This not only serves as a stepping stone for future speech subject recognition but also presents a fresh perspective for the exploration of linguistic logical structures.
