AI Commercial Voice Generator — Read The Ad, And Run It
People search this phrase for two different reasons: they want a voice that can read an advert, or they want to know they are allowed to use the voice commercially. This page answers both — yes, and yes on a paid plan, with no buyout and no attribution.
An AI commercial voice generator produces advertising voiceover from a written script — the read that goes on a radio spot, a social ad, a pre-roll, an in-store loop or a client video. The phrase also gets used to mean an AI voice you are licensed to use commercially, which is the more important question in practice. Here both hold: the voices are built for ad reads, and paid plans carry full commercial usage rights with no attribution requirement and no usage window that expires.
15 free credits on signup — enough for one complete track with cover art. No card required.
Eight Ad Formats And What They Need
Commercial reads are defined by the slot they have to fit. Word count is the real brief, and the register comes second.
15-second pre-roll
~35 wordsOne idea, one name, one action. Anything else and the skip button wins before you get to it.
30-second radio spot
~70 wordsThe classic. Offer, reason, call to action, and the phone number or web address said twice.
60-second radio spot
~150 wordsRoom for a scenario before the offer. The only ad length that can afford a story.
Social & paid video ad
~40 wordsWritten assuming half the audience has the sound off, so the voice reinforces rather than carries.
In-store & retail loop
NeutralPlays every eight minutes to staff as well as customers. Choose a voice that will not become hated.
Explainer & product demo
~450 wordsThree minutes of clear informational read. Register matters more than energy here.
Real estate & walkthrough
WarmProperty tours where a warm read makes a room sound like somewhere to live rather than a listing.
On-hold marketing
CalmHeard by people who are already slightly annoyed. Calm and brief, never enthusiastic.
How to Make a Commercial Voiceover in 3 Steps
Count the words before you write the copy.
Write to the slot, not to the page
Roughly 150 words a minute, so about 70 words for a 30-second spot and 35 for a 15-second pre-roll. Put the product name in a short sentence of its own so it lands.
Match the voice to the product
Nova for energy and retail, Ash for straight and informational, Onyx for weight and premium, Coral for warm and local. The wrong register undoes good copy immediately.
Generate, time it, then download
Play it against a stopwatch before you build the spot. Download the WAV on a paid plan — which is also what carries the commercial usage rights.
Ad Copy Lives On Short Sentences
There is no SSML here to force emphasis, so the copy has to do it. A product name buried mid-sentence disappears; the same name alone in a short sentence lands.
“At Harding’s Garage we offer a comprehensive range of winter vehicle checks completely free of charge throughout November and December for all makes and models.”
“Free winter check at Harding’s Garage. Every make, every model. All November. Book online, or call in.”
“Fieldnote is a really useful notebook application that works even when you do not have an internet connection available.”
“Fieldnote. The notebook that works with no signal. Twenty percent off with the code CLOSE.”
“Come and visit our new store which has just opened on the high street this weekend with lots of great offers available.”
“We are open. Bellweather Books, twelve High Street. Saturday from nine. Everything twenty percent off.”
The Licence Is The Part People Get Wrong
Plenty of free voice tools produce a usable ad read and then bury the fact that the free tier forbids commercial use, or requires attribution, or expires. That is a bad thing to discover after the campaign is live. Here it is simple: free credits are for evaluating, and any paid plan carries full commercial usage rights with no attribution and no time limit on the spot.
- Full commercial usage rights on every paid plan, from $15 a month
- No attribution, no buyout, no usage window that expires mid-campaign
- No performer to re-clear when a spot gets extended or goes national
- Mono 24 kHz WAV for agency and station delivery
- Test the script free first — 15 credits cover a complete read
Ad Reads Sized To The Slot
Each of these is written to a real word count. Swap in your own offer.
30-second radio
“A confident seventy-word radio spot for a local garage offering free winter checks through November, ending with the phone number said twice, friendly not shouty”
15-second pre-roll
“A thirty-five word pre-roll for an offline notebook app: what it does in one line, the discount code, and where to get it. One idea only”
60-second story spot
“A hundred and fifty word radio spot that opens on someone missing a train, turns into the offer from a commuter cycle shop, and closes on the address”
In-store loop
“A calm neutral in-store announcement for a garden centre promoting the winter plant sale, written to be heard eight times an hour without becoming irritating”
Property walkthrough
“A warm two-minute narration for an estate agent video tour of a converted mill flat, describing the light, the mezzanine and the river view, unhurried”
On-hold marketing
“A short calm on-hold message for a plumbing firm mentioning the emergency callout line, the online booking page, and thanking the caller for waiting”

Frequently Asked Questions
Mostly about licensing, because that is what people are really checking.
Am I actually allowed to use the voice in a paid advert?
On a paid plan, yes — those carry full commercial usage rights, which covers a radio spot, a social ad, an in-store loop, a client campaign or a monetised video. On the free tier you cannot download the file at all, so commercial use is not really on the table there: streaming and a share link are for evaluating the voice before you commit. If you are producing for a client, be on a paid plan.
Do I have to credit anyone, or pay again if the campaign runs longer?
No on both. There is no attribution requirement, and no usage window — the part of hiring a voice actor that catches people out is the buyout, where a two-week radio buy costs one fee and extending it to national costs another. A generated read has no performer to re-clear, so a spot that keeps running does not keep costing.
Which voice should I use for an advert?
Nova is bright and energetic and carries a thirty-second read without flattening out, which makes it the default for retail and social. Ash is clear and direct for straight informational spots. Onyx is deep and authoritative when the product wants gravity rather than enthusiasm — cars, finance, anything premium. Coral is warm, which suits local businesses and services where you want a person rather than a pitch.
How long can an ad read be?
Up to 4,000 characters per generation, about 650 words or four minutes — far beyond any advert. What matters more is fitting your slot: roughly 150 words is a minute, so a 30-second spot is about 70 to 75 words and a 15-second pre-roll is about 35. Write to that count, generate, and time the playback. There is no length slider, so word count is the control.
Is there a free way to test a script before I pay?
Yes, and it is the sensible first step. 15 credits on signup with no card covers one complete generation, so you can hear your script read aloud and check whether it fits the slot before spending anything. Timing a script by reading it in your head is the single most common way ad copy ends up two seconds too long.
Can I get a specific accent for a regional campaign?
No. There is no accent selection and all nine voices are English-native, so a campaign that specifically needs a Scottish, Australian or Indian-accented read is not something this can do. If regional accent is part of the brief, hire for it. What you can steer is tone and register through how the script is written.
Can I control emphasis or timing with SSML?
No — SSML is not implemented, and there are no pause, emphasis or speed tags. In advertising that matters more than usual, because ad copy lives on emphasis. Your tools are sentence length and punctuation: end a sentence where you want a beat, and put the product name in a short sentence of its own so it lands.
What file do I get, and will a radio station accept it?
A 16-bit mono WAV at 24 kHz. Mono is standard for a voice track, and uncompressed is what a station or agency will want rather than an MP3. Some broadcasters specify a higher sample rate for final delivery, so check the spec — resampling a 24 kHz voice track up is routine, but it is better to know the requirement before you build the spot around it.
