How to add an AI voice to a TikTok
- Write a short, punchy scriptMost TikToks work best with 50 to 150 words. Lead with the hook, then deliver the payoff fast.
- Pick a voice and set the pacePreview a few voices and bump the speed up a notch for that quick, scroll-stopping delivery. Lower the pitch slightly for a dramatic storytime voice.
- Generate and download the MP3Enter the 5-digit security code, press generate and download your clip. On a phone, it saves to your downloads folder.
- Add it in your editorIn CapCut or a similar editor, import the MP3 as an audio track, then add captions and trim clips to the beat of the voice. Upload the finished video to TikTok.
Hooks and scripts that work with AI voices
On TikTok, you have about two seconds to earn the next ten. A text to speech voice is perfect for this because it delivers every hook with the same clean timing, take after take. Here are three short scripts you can adapt:
Life hack (about 15 seconds):
Stop throwing out stale tortilla chips! Spread them on a tray, bake at three fifty for five minutes, and they’re crunchy again. You’re welcome.
Storytime opener:
So my landlord texted me at two a.m.; and what he asked me to do… I still can’t believe it. Part one.
Small business product reveal:
We hand-pour every candle in our garage in Austin, Texas. This one smells like a campfire and fresh pine. It ships Monday. Link in bio!
The exclamation points add a longer, energetic pause, while the semicolon in the storytime hook creates a beat of suspense before the reveal. Spell numbers and times as words (“three fifty,” “two a.m.”) so the voice reads them naturally.
Built-in TikTok voices vs. Speechma
TikTok’s in-app text to speech is handy for quick captions. Speechma is useful when you want more choice and control.

Quick tips for viral-ready AI voiceovers
- Front-load the hook. Put the most surprising line first, not your intro. “Nobody tells you this about renting in New York” beats “Hey guys, welcome back.”
- Batch your week. Write five scripts on Sunday, generate them in one session and use “download all” to get every clip in a single ZIP.
- Use one clip per scene. Shorter clips let you cut the audio tightly to each shot.
- Match captions to the voice. Run the MP3 through Speech to Text with sentence timestamps to time on-screen captions.
- Add a sound effect. A whoosh or pop from the Sound Effects Generator makes transitions land.
- Want a totally unique voice? Describe one with Voice Design, such as “sarcastic young woman, dry humor, American accent.”
Keep it fun, keep it honest
Don’t use AI voices to impersonate real people, celebrities or creators. Character voices and original designed voices are the safe, fun option. Follow TikTok’s community guidelines, including labeling realistic AI-generated content when the app requires it, and see our AI voice ethics policy.
