Reform and Practice of Public English Examination Mode in Colleges and Universities Using Big Data Analysis and Speech Recognition

Abstract

In terms of the CPE (College Public English) test mode, it suffers from inefficiency and uniqueness. The test must be comprehensive and objective in order to serve as a standard for evaluating English proficiency. Promoting English examination reform and practice is extremely important for English teachers. In light of the current situation, the CPE test system is being researched and designed using BD (big data) analysis. To establish the index system and parameters for evaluating test questions, the test database maintenance module uses a method based on problem-solving theory. For pronunciation recognition, error judgment, and scoring of spoken English, speech recognition and HMM (hidden Markov model) scores are used, and the final spoken English score is obtained through percentile transformation. In intelligent scoring, the AdaBoost CT (adaptive enhancement classification) algorithm is introduced, and various algorithms are compared through extensive literature reading. The results show that when the parameter is set to 50, the AdaBoost CT algorithm has the highest accuracy, at 88.39%. The platform improves students’ learning efficiency and quality by diagnosing their learning problems and intervening in their learning in real time. The results are significantly better than those of other students.

Using Speech Recognition Algorithms to Improve Listening Training in College English Listening Instruction

“…Jingning (2024) explores speech recognition applications in English education through mobile sensor networks. Inceoglu, Chen, and Lim (2023) compare L1 listeners and automatic speech recognition systems in assessing L2 intelligibility Zhu (2022). discusses the reform and practice of public English examination modes in colleges and universities using big data analysis and speech recognition Xu (2022).…”

“…They introduce innovative auxiliary teaching systems(Bao & Lv, 2022) and examine the use of intelligent speech recognition systems to improve English learning outcomes(Luo, 2022). Additionally, studies address pedagogical optimizations(Liao, 2022) and the impact of technology on examination reforms(Zhu, 2022). The integration of IoT(Liu, 2022) and flipped classrooms (Jiang et al, 2021) further expands the scope of application.…”
