AI-Generated Comment on the Study
Flipped classrooms in international collaborative learning require lecture videos in multiple languages, which places a considerable burden on instructors. Generative AI-based speech synthesis offers a potential solution, but how learners perceive such voices has not been sufficiently examined.
This study builds a pipeline that automatically generates Japanese and English lecture videos from PowerPoint slides and scripts, and compares natural speech, a synthetic voice trained on the instructor's own voice, and standard TTS voices. The finding that the trained synthetic voice was rated close to natural speech, together with the study's attention to ethical issues such as consent and disclosure of AI-generated audio, reflects a thoughtful integration of education research and speech technology.
Future integration with XR, the metaverse, and learning analytics promises a practical foundation for supporting international collaborative learning.
