This paper explores the evolution and impact of Artificial Intelligence (AI) technologies in second language learning, particularly focusing on speaking and writing skills. It traces the development from early Computer-Assisted Language Learning (CALL) to current AI-powered tools, highlighting the transformative potential of technologies like Automatic Speech Recognition (ASR), Text-to-Speech (TTS), Intelligent Personal Assistants (IPAs), and AI-driven chatbots. The paper discusses various applications, including Cool English’s speech assessment tool, CoolE Bot for conversational practice, and AI-based grammar checkers. While acknowledging the benefits of these technologies in providing personalized learning experiences and immediate feedback, the paper also addresses challenges such as potential biases, ethical concerns, and the need for critical evaluation of AI-generated content. The authors emphasize the importance of balancing AI integration with traditional teaching methods and fostering responsible use of these tools in language education.
