Traditionally, feedback is regarded as crucial in the context of learning and teaching public speaking. In the current course, we analyzed the feedback provided to students by an artificial intelligence (AI) coach and students' learning experiences in developing public-speaking skills via this tool. The MySpeaker Rhetorich speech coach application served as a platform for practicing public speaking within the course. Students found AI-powered feedback to be advantageous and less biased than feedback from their peers. However, although the AI coach offers benefits, it is not without challenges, and currently, solely relying on it as a teaching tool appears inadequate. Course: Voluntary AI-powered public-speaking course. Objectives: Participants are able to prepare and deliver a speech and gain basic knowledge and understanding about speech composition and delivery. Participants learn to assess their public-speaking skills by receiving feedback from AI and peers and apply their knowledge on public speaking by providing feedback to others.
