Choosing the right voice-over for your video
| Goal | Recommended voice |
|---|---|
| Sell a promo, announce an event | Energetic, upbeat voice |
| Explain a service, build trust | Warm, calm voice |
| Premium or luxury brand | Deep voice, slow pace |
| Teaser, big reveal | Whispered or suspenseful voice |
| Storytelling, brand story | Cinematic voice |
Writing a script that sounds good out loud
A script you hear isn't the same as a text you read. A few rules, covered in detail in our guide to writing a voice-over script:
- Short sentences, one idea per sentence.
- About 2 to 3 words per second: 30 seconds is 60 to 80 words.
- Simple words people understand the first time they hear them.
- Write numbers the way they're spoken if needed: "twenty-five percent."
Voice-over and on-screen text: getting the balance right
On social media, part of your audience watches with the sound off. On-screen text should pick up the key words of the voice-over, not the whole script. On YouTube or your website, the voice-over can carry more of the message, like in an explainer video. For a podcast or a channel, a YouTube intro with a single voice-over line creates a real signature. You can try a voice-over right now.
Why an AI voice-over beats recording it yourself
Recording it yourself takes a decent mic, a quiet room, several takes, then syncing it all to the visuals. The slightest script change means starting over. With ManyMotion's voice-over, changing a sentence takes seconds and the sync is automatic. Above all, you gain the freedom to test: two voices, two tones, two hooks, and you keep the best one.
Frequently asked questions
What language is the voice-over in?
+
The voice-over follows the language of your request: ask in English and you get an English voice-over. You can choose from 8 voices, with tones ranging from warm to cinematic.
Can I use my own voice?
+
ManyMotion generates the voice-over with its own voices. If you want to use your own voice, you can add your recording in a video editor after exporting.
Can I create a video without a voice-over?
+
Yes. Just say "no voice-over" in your request, and the video keeps the music, sound effects and animated text.
Does the voice pronounce names and places correctly?
+
Most common names come out fine. If a name is mispronounced, spell it phonetically in your script to fix it.
Can I change the voice after the video is created?
+
Yes, just ask for "a deeper voice" or "a more upbeat voice." The voice is regenerated and re-synced for 3 credits.
