The objective of this study was to examine users’ perspectives and levels of satisfaction with AI Pengtalk, an English-speaking application powered by artificial intelligence. To accomplish this objective, three groups (395 students, 60 parents, and 33 teachers) were surveyed regarding their attitudes toward AI Pengtalk and satisfaction with the application. Findings indicated that all groups considered AI Pengtalk a useful tool for enhancing their English-speaking ability. Positive results were obtained across all groups in terms of their perceived efficacy of the system for improving English ability. Participants reported that the application provided them opportunities to practice specific language topics. Additionally, participants stated that developing a free conversation capability was one of the conditions for maximizing the system’s potential as an English-speaking application. Participants also commented that the interface was user-friendly and that its instructions and explanations given to users were straightforward, indicating general satisfaction with AI Pengtalk. Despite these perceived benefits, all groups reported limited usage of the application. Several technological difficulties such as misrecognition of students’ utterances were also discovered. Future recommendations for this application’s usage were discussed from both pedagogical and technological standpoints.
