introduction

The emphasis on the core competencies of the English subject, especially the cultivation of cross-cultural communication skills, was emphasized in the "National Curriculum Standards for Ordinary High School English". It is pointed out that there are many problems in current high school English oral teaching, such as the neglect of oral skills in teaching, large class sizes restricting students' opportunities for oral expression, and untimely classroom evaluations, which limit the development of students' oral abilities. With the development of conversational artificial intelligence technology, its application in the field of language teaching provides new ways to solve these problems. Dialogue based artificial intelligence can provide personalized learning plans and resources to meet the personalized needs of students. Although research has explored the application of conversational artificial intelligence in English teaching, there is still insufficient research on improving oral expression ability. This article aims to explore practical strategies for using conversational artificial intelligence to promote high school students' oral expression ability, in order to support the development of students' cross-cultural communication skills.

Strategies for Promoting High School Students' Oral Expression Ability through Dialogue based Artificial Intelligence

Dialogue based artificial intelligence generates language models similar to human text through deep learning, analyzes learning patterns and relationships in text datasets, and generates natural and diverse answers. It provides learners with a safe and supportive environment, real-time feedback to guide progress, integrates natural language processing and machine learning algorithms, and meets personalized needs. Oral expression ability includes standard pronunciation, accurate vocabulary and grammar, clear and coherent expression, and effective interactive communication. High school English exams should focus on the actual effectiveness of students' expressions, taking into account fluency, accuracy, and appropriateness. Dialogue based artificial intelligence can promote high school students' oral expression ability in three aspects: 1 Utilize tool attributes, alleviate students' anxiety, create a realistic and relaxed environment, and enhance interest and initiative; 2. Utilize real-time interactive features, provide resources and environment for foreign language communication, solve language communication problems, and improve fluency; 3. Utilize the advantage of instant feedback to help students pay attention to language forms, reflect on language use, and improve accuracy.

Practice of using conversational artificial intelligence to promote high school students' oral expression ability

This article explores how to use conversational artificial intelligence (AI) to enhance the oral expression ability of high school students through practical cases. Firstly, conversational AI as a tool can help reduce students' oral anxiety and enhance their willingness to communicate. Research has shown that second language confidence and motivation are positively correlated with communication willingness, and AI can provide a stress free communication environment to help students maintain communication confidence. For example, AI can communicate in simple English based on students' instructions, helping them overcome anxiety about inaccurate pronunciation or language.

Reflection and Summary

Dialogue based artificial intelligence effectively improves high school students' oral expression ability by alleviating students' anxiety, enhancing their willingness to express themselves, providing practice opportunities, and instant feedback. However, there are shortcomings, such as difficulty in meeting high-level cognitive needs, generating expressions that do not match the context, inaccurate understanding of instructions, and potential reduction in the quality of interpersonal and emotional communication. Teachers need to guide students to use language correctly, leverage their strengths, and promote the development of language expression abilities.
