Text to Speech for Reels, Shorts and TikTok: A Quick Guide
Short videos on Instagram Reels, YouTube Shorts and TikTok reward speed. You can publish more often when you do not have to record your voice every time. AI voiceovers have become very common in short videos for facts, stories, motivation, news and tutorials. Here is how to do it well, so that your videos look original and not low effort.
Write a script for 20 to 40 seconds
At a normal speaking pace, 30 seconds is about 70 to 90 words. Short videos need a strong first line, because viewers decide within two seconds. Start with a question, a surprising number or a bold statement. Then give two or three quick points and finish with a short closing line.
- One idea per video.
- Very short sentences, no long explanations.
- No introduction like "Hello and welcome". Start with the point.
Pick the right voice
For short videos, a clear and energetic voice works best. Facts and tips suit a confident medium voice, and stories suit a warmer, slower one. Stay with the same voice for your channel so viewers recognize you.
Generate and edit in your phone or computer
- Generate the voiceover from your script and download it.
- Import it into an editor such as CapCut or InShot.
- Add visuals that change every two to four seconds: stock clips, screenshots, images or your own footage.
- Add captions. Most viewers watch without sound, so large, readable subtitles are important. Highlight key words.
- Add soft background music at a low level, and check that the voice stays clear.
Things that reduce reach
- Reusing other people's videos without changes. Platforms promote original content.
- Copyrighted music or clips. Use licensed or platform-provided sounds.
- Misleading claims. Check facts before you publish.
- Very long sentences with no pause, which sound rushed.
Be open about AI
Some platforms ask creators to label content that uses synthetic voices, especially when it looks realistic. Check the rules of each platform and add the label when needed. It also protects your account.
