This study focuses on designing a phonetic practice game for children 3-6 years old after cleft lip-palate surgery following the principles of inclusive education methods and instructional game design. The research results have yielded a system of phonetic standardization training games. These games are designed according to each phonetic standardization content in the current preschool education curriculum. The results of this study assist teachers in conducting phonetic standardization tasks for children such as: refining pronunciation organs, training listening and speaking abilities, refining pron unciation, perfecting standard phonetic norms, training speech intonation, correcting children's pronunciation errors... Additionally, parents can utilize this system of corrective games to play with their children.
