Free Commercial Voice Over Generator

How it works

1. Paste your ad script. Free clips are up to 500 characters, enough for most 15 and 30 second spots. Longer scripts are split into parts you join into one MP3.
2. Pick a voice that matches your brand. Christopher is preselected; open "More options" to change speed and pitch.
3. Press generate, time the clip, and download the MP3. Add music and sound effects in your video or audio editor.

How long should a commercial voice over script be?

Whether it is a TV spot, a radio read, a YouTube pre-roll or a social video ad, timing comes first. Most ad reads run at about 2 to 2.5 words per second. That gives you a simple rule for commercial voice over scripts, with a little room left for music and a logo at the end:

• 15 second spot: about 30 to 38 words. One idea, the brand name, one call to action.
• 30 second spot: about 60 to 75 words. A hook, two benefits, the offer, and the call to action.
• 60 second spot: about 125 to 150 words. Room for a short story or a customer problem and its fix.

Choosing a voice for your brand

• Friendly local business (bakery, cafe, salon): a warm, relaxed voice such as Emma, Ava or Andrew.
• Sale or event (car dealer, furniture store): a bright, confident voice such as Christopher or Jenny, read a little faster.
• Tech or app launch: a clear, modern voice such as Brian or Aria, at normal speed.
• Premium or calm brand (spa, bank, law firm): a slower, lower read. Lower the speed by 5 to 10 percent.
• Selling in the UK, Australia or India? The language menu has local English voices too.

Tips for a TV or radio commercial voice over

• Write for the ear. Short sentences, one number at a time, and the brand name at least twice.
• Spell out numbers and times the way they should be said, such as "six a.m." or "Route 9".
• Use the Speed slider in More options to fit an exact length. A 30 second script that runs 33 seconds often fits at plus 8 to 10 percent.
• Add a short pause before the call to action with [pause 1s].
• Make two versions in two voices and play them to someone who has not read the script.

A simple structure for any ad script

Most short commercials follow the same four beats. Start with a hook in the first three seconds: a question, a sound word or a bold promise, such as "New year, new routine?". Then name the brand and give one or two clear benefits. Next comes the offer, with a reason to act now, like a date or a limited deal. End with the call to action and the brand name again.

Read your script out loud once before you generate it. If you run out of breath or trip on a phrase, the AI voice will sound rushed there too. Cut that line or split it in two.

What it does and does not do

• It reads your ad script in a natural AI voice and gives you an MP3. You can change the voice, pitch and speed.
• It does not add music, jingles, sound effects or echo. Add those in your video or audio editor.
• It does not write the script for you, and it does not copy any real person or brand voice.
• It does not clone voices. Longer scripts and more voices are on the paid plans, see /pricing.
