Narrating a full online course used to require a professional microphone, soundproofed room, and hours of recording and editing. AI TTS eliminates all of that. Here's the practical guide for course creators.
What Works and What Doesn't
AI TTS works excellently for instructional narration, lesson introductions, concept explanations, and quiz instructions. It works less well for highly conversational content, Q&A formats, and anything where spontaneity is part of the value. For those elements, consider a combination approach — AI narration for the main content, recorded voice for the "personal" moments.
Optimal Settings for E-Learning
- Speed: 0.9× for dense technical content, 1.0× for narrative-style courses
- Voice: Use a consistent voice across all modules — listeners become accustomed to a specific voice
- Script structure: Each module: welcome/overview (60 seconds), main content (3–5 minutes), summary (30 seconds)
Handling Technical Vocabulary
AI voices sometimes mispronounce industry-specific terms. Test your script before finalizing. For persistent mispronunciations, add phonetic spelling in your script: write "Kubernetes" as "Koo-ber-ne-teez" or use hyphens: "API" as "A-P-I". Most browsers handle acronyms well when spelled out letter by letter.
Publishing Platforms That Accept AI Narration
Teachable, Thinkific, Kajabi, Udemy, Coursera (for partners), and Podia all accept AI-narrated course videos without restriction. None of these platforms require disclosure that narration is AI-generated for general course content.
