Pronunciation plays an important role in oral communication, but it is one of the most challenging aspects of second language learning, especially for adult ESL (English as a Second Language) learners. Effective feedback mechanisms can help learners develop accurate pronunciation and intelligible speaking skills. This article reviews various feedback strategies that can help improve pronunciation, including precision correction, recasting, meta-linguistic feedback, and self-monitoring techniques. It also discusses the use of speech recognition software and artificial intelligence-based pronunciation apps that provide real-time, personalized correction.

       The results of the study show that the combination of the lecturer is significantly increases the phonetic accuracy of students. This article emphasizes how important it is when they provide practical recommendations for language teachers, especially the timely, timely and constructive focusing on developing pronunciation.
