This study aims to examine the effects of artificial intelligence-based language learning tools on EFL learners' speaking skills. Through semi-structured interviews with participants selected by criterion sampling, the effects of AI-based applications on EFL learners' speaking skills were examined. The findings show that AI tools provide significant improvement in speaking skills such as pronunciation, vocabulary, fluency and grammatical accuracy. However, there are also some limitations such as technical problems and issues with feedback and personalization mechanisms. While this study reveals the potential of artificial intelligence in the field of language teaching, it also emphasizes the need to develop tools with personalized and user-friendly interfaces in order to use this new technology more effectively. The results provide important clues on the design and development of AI-based language learning applications and can guide future research in the field.
