Radio commercials

Create hard-hitting promotional messages for your advertisers

What this page is for

A radio commercial is a short audio message (15 to 60 seconds) promoting a product, a service, an event or a business. From Creation › Commercials you will find the list of your spots and the New commercial button.

  • Length: 15, 20, 30, 45 or 60 seconds — 30 seconds is the radio standard
  • Structure: hook, message, call to action
  • Tone: matched to the advertiser and their audience

Step by step

  1. Click New commercial.
  2. Enter the Spot title (for example “Summer promo - Le Soleil Restaurant”).
  3. Click Choose a voice: the side panel shows the catalogue with previews.
  4. Pick an Intonation if you want a particular colour (“Standard” by default).
  5. Select a Music bed — optional, but strongly recommended on a commercial.
  6. Write the Spot script, or click Generate with AI to start from a draft.
  7. Check the Credit estimate shown under the script, then click Generate the spot.
  8. Listen to the preview, then Edit to fine-tune or Download ZIP to get the file.

The script generator

The Generate with AI window asks you four things:

  • Commercial template: a ready-made structure, or “free” to let the AI compose
  • Spot description: the essentials of the offer (“Italian restaurant, 15 € set menu, family atmosphere, open 7 days a week”)
  • Tone: Energetic, Professional, Warm or Urgent
  • Length: 20, 30 or 45 seconds
Tip : Generating or improving a script costs nothing. Only audio generation uses credits, so feel free to rerun the draft several times before producing the sound.

Advanced settings

The Advanced settings (volume, intro / outro) accordion gives you control over the mix:

SettingRangeDefault value
Voice volume50 to 200 %100 %
Intro — silence before the voice0 to 5,000 ms1,000 ms
Outro — silence after the voice0 to 5,000 ms1,000 ms
Music bed volume5 to 50 %15 %
Good to know : The music bed volume only appears if you have selected a bed. A value between 12 and 18 % keeps the voice perfectly intelligible.

Writing a good commercial

  • Hook: grab attention in the very first second
  • Benefit: say what the customer gains, not what the advertiser sells
  • Proof: a price, a date, a concrete figure
  • Call to action: one single action, clearly stated
  • Contact details: address or website, repeated if that is the main message
Good to know : Count roughly 2.5 words per second: 35 words for 15 seconds, 75 words for 30 seconds, 150 words for 60 seconds.

Credit cost

The cost is based on the actual length of the audio produced, at 1 credit per 3 seconds (minimum 1 credit):

Spot lengthApproximate cost
15 seconds5 credits
30 seconds10 credits
45 seconds15 credits
60 seconds20 credits
Warning : The Regenerate button only appears if you have changed the script, the voice, the intonation or the music bed — and regenerating uses new credits.

  • Without a subscription, downloads are capped at 3 free audio files.
