To obtain and analyze the data, a questionnaire was sent to 83 participants from different proficiency levels and backgrounds. According to the results obtained, participants with higher proficiency levels tend to rely more on ChatGPT and report having moderate improvements, especially in writing, vocabulary and grammar. Additionally, the results of the questionnaire show a low use of the oral features that ChatGPT offers. To promote this oral feature, a didactic activity was designed to help students improve their speaking fluency through interactive conversations with ChatGPT. This activity aims to promote learner autonomy, digital competence and critical understanding of how to use AI tools. Although some limitations in the use of ChatGPT were noted, the results suggest that this tool can help the language learning process when it is used with proper guidance. Rather than replacing traditional methods, AI should serve as a complementary tool to support more flexible and personalized learning.
