E-learning production workflow: 1. Write your course script with clear sentence structure and natural pauses 2. Choose a voice that matches your content tone — warm for soft skills, professional for technical 3. Generate audio chapter by chapter — shorter sections are easier to update later 4. Export as WAV and import into your video editor or LMS 5. Use a consistent Kokoro precision (q4 recommended) across all modules for uniform quality
Tips for better e-learning TTS:
- Break content into 2-3 minute audio segments — this matches learner attention spans and makes updates easier
- Use commas to create natural pauses between concepts
- Number steps clearly ("First, open the settings panel. Second, select...") for technical content
- Generate a sample module first and test with learners before producing the full course

Map E-Learning Narration to Objectives, Screens, and Updates
OfflineTTS can create lesson narration, but it does not design instruction, build a SCORM package, synchronize slides, grade learners, or validate accessibility. Break the script into screen-level segments named after the course structure. Keep one source of truth for on-screen text, captions, and narration so a factual update can be located and regenerated without replacing an entire module.
Prepare a pronunciation glossary for product names, technical terms, acronyms, equations, units, and people. Test that glossary with the chosen engine and voice before production, and use a fluent subject-matter reviewer for translated lessons. Store the engine, language, voice ID, speed, and script revision with every approved segment.
Treat Course Accessibility and Confidentiality as Separate Reviews
Narration can support learners who prefer audio, but an audio track alone does not establish WCAG, ADA, Section 508, or other legal conformance. Provide accurate text alternatives, captions where applicable, keyboard-operable controls, visible focus, and a way to pause or replay content. Test the complete course with relevant assistive technologies and users.
Training material may contain confidential procedures or personal data. Check the engine-language path before entering it: Supertonic and English Kokoro can keep text processing local after required assets load, while several non-English Kokoro languages use the OfflineTTS phonemization endpoint. Apply the organization’s retention, consent, and review rules to exported audio as well as source text.
