TikTok & Reels AI voice generator
Ship vertical scripts with punchy AI narration tuned for retention — ideal for hooks, listicles, and trend explainers.
A TikTok or Reels voice generator turns short vertical scripts into spoken hooks and payoffs you drop under screen recordings or B-roll. MachenVoice is built for 2,000-character blocks so you can regenerate only the opening line when retention drops.

How to do it step by step
- 1
Write hook and payoff as two separate blocks before you open your editor.
- 2
Pick Aria (English - United States) for English hooks or Francisca (Portuguese - Brazil) for Brazilian Reels; preview both if you are A/B testing tone.
- 3
Generate block one, export nothing yet—listen on phone speakers, then tweak punctuation and regenerate.
- 4
Generate block two, play the two-block playlist, and export one MP3 if the cadence feels tight.
- 5
Import the MP3 in CapCut, TikTok, or Instagram, align cuts to breaths, and add captions because many viewers watch muted.
Tips for natural-sounding short-form narration
- Keep the hook under three seconds on paper—one short sentence, no subordinate clauses.
- Use periods instead of em dashes; neural voices handle full stops more predictably at high speed.
- Write numbers as words in hooks (“three steps”) so the voice does not rush digits.
- Avoid hashtag text in the spoken script; put tags only in the caption field of the app.
- If you add trending music later, export dry voice from MachenVoice and mix music in the editor so levels stay legal on each platform.
Which voice should I choose?
| Voice | Why it fits this use case |
|---|---|
| Aria (English - United States) | Fast English hooks for explainers and “stop scrolling” openers. |
| Guy (English - United States) | Slightly lower pitch when your visual brand is bold or fitness-focused. |
| Francisca (Portuguese - Brazil) | Brazilian Portuguese Reels with conversational tone. |
| Antonio (Portuguese - Brazil) | Male PT-BR voice for sports, gaming, and tech tips. |
| Elvira (Spanish - Spain) | European Spanish trend breakdowns. |
| Katja (German - Germany) | German-language short explainers without switching tools. |
Common mistakes
Reading the entire trend context aloud before the hook.
Put context on screen as text; block one should only be the pattern interrupt.
Matching music bed volume to speech in MachenVoice.
Export dry speech; music loudness rules differ per app and country.
Using one block for five tips.
One tip per block or per video—short-form listeners drop when lists run long.
Forgetting safe-area titles.
Preview with platform overlays; leave the first line short so UI does not cover words.
