In a 30-second recipe video, one unclear number can spoil the whole instruction. If “bake for 15 minutes” sounds like “50 minutes,” good visuals will not fix the problem.

Before generating narration with Index TTS, read the script as something people will hear, not scan. Try it aloud once without looking at the images. Any line that feels crowded, vague, or difficult to say deserves another edit.

Give each sentence one task

A sentence that looks tidy on screen may contain too many steps:

Add the butter, sugar, eggs, flour, milk, and vanilla, then mix until smooth before pouring everything into the prepared tin.

For narration, divide it:

Mix the butter and sugar. Add the eggs, flour, milk, and vanilla. Stir until smooth, then pour the batter into the tin.

The listener now has time to follow each action. This approach also works for tutorials, product guides, and short lessons.

Remove avoidable ambiguity

Check dates, prices, measurements, abbreviations, and names separately.

“3/6” can mean March 6 or June 3. Write the month instead. “$25.50” may be clearer as “twenty-five dollars and fifty cents.” If a brand name is easy to misread, add pronunciation guidance before generating the full paragraph.

Long web addresses rarely work well in narration. Show the address on screen and use a simple spoken line such as “Visit the link below.”

Keep longer recordings in sections

Split a longer script by paragraph, scene, or topic. This makes later changes easier.

Imagine an online course announcing that enrolment opens on September 12. The date changes the following morning, but the rest of the introduction remains correct. If the date has its own short section, only that line needs to be replaced.

Save a brief note of the language, speed, and voice settings. It will help the replacement line match the rest of the recording.

Check the audio where people will hear it

A voiceover may sound clear through headphones but less clear through a phone speaker. Play the finished version at an ordinary volume.

If it is for a cooking video, listen while a kettle or extractor fan is running. If music will be added, check the full mix. Pay special attention to times, measurements, safety instructions, and the next action.

Use only your own voice or a reference recording you have clear permission to use. Do not use private clips, public-figure voices, or another creator’s recording without authorization.

Before publishing, check every name, number, fact, and change in tone. Natural-sounding speech can still contain mistakes. A short script review is often quicker than repairing the audio after the video is finished.
