[publication] aicast: Combining AI-Generated and Instructor-Defined Content in Educational Podcasts #research #tugraz

At this year’s ED-Media conference, we introduced a new AI-based concept for educational podcasts: „aicast: Combining AI-Generated and Instructor-Defined Content in Educational Podcasts„.

Abstract:
Generative AI is transforming educational content. In this poster, we present aicast.fyi, an open-source platform for producing personalized educational podcasts that combine AI-generated and instructor-defined content. Each track contains dynamic and fixed segments. Instructors define guiding questions during track design, ensuring alignment with learning objectives. This hybrid approach addresses concerns about maintaining instructional integrity with automation and personalization. The poster provides an architectural overview and demonstrates how the system integrates text generation and voice synthesis to produce audio-based learning experiences. Instructional designers must play an active role in shaping AI-assisted educational tools. This poster invites educators, designers, and researchers to engage with aicast and collaborate on developing high-quality, responsible, and learner-centered audio content. By allowing learners to control content sequences and personalize segments based on their own inputs, aicast.fyi also supports self-regulated learning (SRL), empowering users to take ownership of their educational journey.

[publication] Workshop for Special Interest Group Emerging Technologies for Learning and Teaching: Exploring Educational Podcasts with AI #tugraz #research

We also did workshops at this year’s ED-Media conference. One of them was titled „Workshop for Special Interest Group Emerging Technologies for Learning and Teaching: Exploring Educational Podcasts with AI“ and followed the idea of open discussions.

Abstract:
How can educators unleash the power of AI without losing control over core educational strategies? In this workshop, we introduced aicast, an open-source platform for educational podcasts that combines the best of both worlds: AI-generated elements for personalization and flexibility, and fixed elements, with instructor-defined content to ensure pedagogical accuracy. This hybrid approach reduces the risks associated with AI-generated materials like hallucinations. Attendees experienced how the platform utilizes LLMs like ChatGPT for personalized content authoring and ElevenLabs for high-quality voice synthesis, enabling real-time creation of educational audio content. After a short demo and hands-on session, participants engaged in a guided discussion: What is the core of an educational podcast? Most importantly from the perspective of an instructional designer, how must an educational podcast be? This session was part of the Special Interest Group on Emerging Technologies for Learning and Teaching at the ED-Media 2025 conference.
