A New Frontier in AI-Assisted English Oral Presentation Assessment

English is employed in many tertiary education institutions where oral presentation assignments are delivered entirely in English. To support students who learn English as an Additional Language (EAL) and to address the impracticality of receiving regular teachers’ feedback due to their heavy workload, the team developed SmartPresenter, an online presentation training and grading platform on which EAL students can receive instant AI-generated feedback for their self-directed presentation practices. In addition to providing learning materials and tips that are tailored to the learning needs of EAL students, SmartPresenter offers an extensive set of AI feedback, including eye contact, facial expressions, clear view, vocal fillers, pronunciation, and fluency to support self-paced oral presentation training. Based on the survey results, which revealed that students needed help with presentation skills, and that both teachers and students preferred AI feedback, SmartPresenter was further fine-tuned and piloted in a database subject. The study aims to show the effectiveness of SmartPresenter in facilitating independent learning practices of English oral presentations and in assisting teachers in grading presentation assignments.
