Multilingual Training Content

‍Challenge

‍A corporate training provider needed to deliver content in 8 languages with natural-sounding narration. Their traditional approach required hiring voice talent for each language, scheduling recording sessions, and managing extensive audio editing, making multilingual content prohibitively expensive and time-consuming to produce and update.

‍

Solution

‍An AI voice generation system using ElevenLabs, Make.com, and Claude API that:

• Transformed written training content into natural-sounding narration across 8 languages
• Maintained consistent voice quality, pacing, and pronunciation
• Preserved emotional tone and emphasis appropriate for educational content
• Enabled quick updates when content needed revision
• Synchronized audio with visual elements automatically
• Generated transcripts and closed captions for accessibility

‍

Implementation

‍The system was implemented over 4 weeks:

1. Voice selection and fine-tuning for each target language
2. Development of pronunciation guidelines for industry-specific terminology
3. Creation of content processing workflow from text to final audio
4. Implementation of synchronization with visual training materials
5. Quality assurance process with native speaker review

‍

Results

• Voice production costs reduced by 91% compared to traditional recording
• 1.5 FTE saved in audio production coordination
• Content available in 8 languages compared to previous 3
• 48% increase in international course completion rates
• Update time reduced from weeks to hours when content changes were needed

Accessibility Improvement

The system's automatic transcript generation also improved accessibility compliance and enabled better searchability of training content.
