International Journal of Web Applications Woyou Zhang 16 2 2024 https://doi.org/10.6025/ijwa/2024/16/2/44-51 https://www.dline.info/ijwa/fulltext/v16n2/ijwav16n2_2.pdf This article presents a novel approach to college English autonomous learning-a voice command model based on the Viterbi algorithm. This innovative model is designed to enhance students’ English proficiency and learning outcomes in an autonomous learning environment. The article begins by outlining the context and importance of the model’s development, then delves into the key technologies utilized in its construction, such as speech recognition, the Viterbi algorithm, and feature extraction. The article concludes with a validation of the model’s effectiveness and superiority through experiments, demonstrating its ability to accurately interpret students’ voice commands and thereby improve the efficiency of college English autonomous learning.
