In order to improve the efficiency of English classroom teaching and students’ interest in English learning, this paper constructs an intelligent English classroom with intelligent computer language, and improves the computer language processing algorithm according to the needs of English speech processing in intelligent teaching. In the process of adaptive beamforming, the minimum mean square error algorithm can be used to dynamically adjust the weight to effectively enhance the target speech signal, and the clarity of the signal can be further improved by single-channel noise suppression technology. The experimental results show that the proposed method has better cancellation effect on interference signals in other directions, which proves the effectiveness of the proposed method. From the evaluation results, teachers’ evaluation is above 87 points, and students’ evaluation is above 88 points, which shows that both teachers and students have a certain degree of recognition of English intelligent classroom teaching system.
