Authomatic-dubbing for documentary clips for children

Nextus is a European educational platform that provides pedagogical resources inspired by high-quality documentaries. Available in 8 languages — Catalan, Spanish, English, Portuguese, German, Greek, Macedonian, and Italian — the platform hosts over 1,500 educational materials, including lesson plans, documentary clips, and full-length films. Each resource is carefully tagged by theme, subject, SDG (Sustainable Development Goals), and age group, helping educators create meaningful, real-world learning experiences.

All our audiovisual content is currently available in its original language version, which can be a barrier for younger learners (ages 8–11) who are not yet used to reading subtitles, and for those with reading or visual difficulties.

We’re looking for AI-powered solutions capable of automatically dubbing audiovisual content into the 8 languages of the Nextus platform — making our educational materials more inclusive, accessible, and engaging for all learners.

Imagine a tool that can:

• Automatically detect and translate speech with high accuracy

• Synchronize voices and tone naturally with the original video

• Support multiple voices and accents to enhance authenticity

• Ensure quality and consistency across all languages

Therefore, we need to develop an AI-based dubbing or voice-generation system that can seamlessly adapt our documentary content for diverse learners, breaking language and accessibility barriers.

Join this challenge and help us make education truly multilingual and inclusive!
