# AI voiceover for videos, ads and explainers

> An AI voiceover replaces a recorded voice track with synthetic speech. Here you paste a script of up to 4,000 characters, choose from 365 voices and a speed from 0.75× to 1.5×, and download an MP3 to place under your video. A 60-second voiceover is about 900 characters, $0.05 to $0.09 at 1 credit per character.

Paste the script, choose a voice that fits the brand, set the pace, and drop the MP3 under your footage.

## What makes a good AI voice over

- **A voice that fits**: Upbeat hosts for social, calm narrators for explainers, confident voices for product ads.
- **Timing you control**: Speed chips stretch or tighten a read to fit a cut without re-recording.
- **Fast revisions**: Changed one line? Regenerate that line instead of booking another session.
- **Same voice every time**: Use the same voice and speed across a series so episodes sound consistent.

## How to add an AI voiceover to a video

1. **Write for the ear**: Short sentences, about 150 words a minute, with the hook in the first line.
2. **Generate the voice track**: Pick a voice and speed, generate, and listen against your cut.
3. **Place it in your editor**: Download the MP3 and drop it into CapCut, Premiere, DaVinci Resolve or any editor.

## Voiceover for YouTube, TikTok and ads

Short-form video lives on the first two seconds, so lead with the hook and keep sentences under fifteen words. For YouTube explainers, a calm narrator at normal speed holds attention over several minutes; for TikTok and Reels, an upbeat voice at a slightly faster speed matches quick cuts. Ads need the product name early and the call to action last.


## Is there a free AI voice over generator?

Many tools advertise one, usually with a daily cap, a watermark or no commercial rights. Here the offer is simple: 5,000 free characters when you sign up, about 5 minutes of English, with commercial use allowed under our terms. After that you pay $0.06 to $0.10 per 1,000 characters.


## Before you publish

Listen to the whole track once, at full volume, with the video. Check names, prices and dates, and rewrite any word the voice misreads the way it should sound. If you publish a voiceover made with OpenAI voices, OpenAI's policies ask you to tell viewers the voice is AI-generated, which a line in the description does.

## AI voiceover FAQ

### How long can one voiceover be?

One clip reads up to 4,000 characters, about 4 minutes of English. Longer narrations work in parts with the same voice and speed, joined in your editor.

### Can I monetize videos with an AI voiceover?

Yes, for videos, podcasts, ads, courses and apps, within our terms and the usage policies of the model you used. Two rules matter most: do not present a synthetic voice as a real person's, and if you publish audio made with OpenAI voices, OpenAI asks you to tell listeners the voice is AI-generated. We cannot promise a voice is exclusive to you; other customers use the same voices.

### Which voice works best for TikTok?

Bright, energetic voices at 1.25× usually suit fast cuts. Try MiniMax's Upbeat woman or Radiant girl, OpenAI's Nova, or Gemini's Puck, and compare them on your first line.

### What does a one-minute voiceover cost?

About 900 characters of English, so $0.05 to $0.09 at 1 credit per character, depending on your plan or pack. The exact price shows before you generate.
