EduPrime is an online professional skills training platform with over 500,000 users. As overseas users grew from 10% to 40% of the user base, international course localization became a strategic priority.
Challenge
- Traditional multilingual course production: hiring professional voice actors per language, $5,000+ per course
- 15 language versions of a single course took 4-6 months for recording and post-production
- Content updates required re-recording all language versions, extremely high maintenance cost
Solution
Adopted ElevenLabs AI voice synthesis and voice cloning:
- Created AI voice models per course for consistent voice quality across all languages
- One-click generation of 15 language dubs from text, using cross-language voice cloning for brand voice consistency
- AI automatically regenerates corresponding voice segments on content updates
- Adjustable speed and emotional parameters for optimized learning experience
Results
- Per-course localization cost reduced from $75K to $11K (15 languages total)
- Full 15-language production-to-launch cycle shortened from 6 months to 3 weeks
- Non-English market users grew 210% in 8 months
- Content update lag reduced from average 45 days to 2 days
