This study examines the role of artificial intelligence (AI) chatbots in improving English speaking skills among university students. The aim of the study is to assess the effectiveness of AI-based tools in improving vocabulary, fluency, and confidence in students. The study used a mixed methodology, including a questionnaire and an analysis of the results of 100 EFL students. The results showed that AI chatbots significantly increase vocabulary and confidence in speaking, but their excessive use can reduce independent thinking and real-world communication skills. The study concludes that AI should be used as a support tool, not a replacement for traditional teaching methods.
