The Voice-Native Classroom: Multilingual AI Co-Teachers for Global ML Education

Most AI tutoring tools ask students to type, which is a barrier for learners working in a second language. This project builds a voice-native AI co-teacher that converses with students in their own language, and is available at any time of the day. Already piloted in a live university course since September 2025, the approach will now scale to reach more than 1,000 students across 50+ countries through Neapolis University in Cyprus and DataTalks.Club, a Berlin-based online community of 80,000 learners – with no tuition and no language barrier standing between students and rigorous ML education.
