How to use it
Create narration for an online lesson from a script you have already written. Paste one short section, choose a voice, and download the MP3 for your course authoring or video editing software.
Write for listening
Introduce the learning objective, explain one idea at a time, and replace references such as 'see above' with words that make sense when spoken.
Generate and review a lesson section
Paste your script and select a voice suited to its language. Listen for technical terms, abbreviations, and transitions before preparing the remaining sections.
Add narration to your course
Download the MP3 and import it into your course editor. Align demonstrations with the narration and leave time for learners to read examples or complete an exercise.
What you can make
- An introduction that states a lesson's objective
- A spoken explanation accompanying a worked example
- Instructions for a practice exercise and its review

Make the result useful
Use a consistent vocabulary
Keep a short list of product names, acronyms, and specialist terms. Spell out unfamiliar abbreviations where appropriate and listen to their pronunciation. Use the same wording across modules so learners can connect the narration with on-screen labels.
Plan around lesson updates
Save scripts and audio with matching section names. Short, self-contained sections let you replace a changed explanation without rebuilding an entire lecture. Keep the written lesson available too, and check audio levels after assembling the course.
