How does Audio.co create ads of a specific duration?

Ads created in Audio.co can be created to a chosen duration/runtime of up to 90 seconds.

Other AI speech synthesis tools usually work to a word count rather than a duration, which is preferred when working with adverts.

When creating an ad, just select "Use target duration" and pick your chosen length.

Audio.co will then work through several stages to create an ad to match your instructions:

1. Scripting: When the ad script is generated, your chosen model and voice will inform how many words Audio.co includes in the initial script.
2. Voice: If your script is still a little long/short, the AI-generated speech can be sped up by up to 10% or slowed down by up to 5% to fit your chosen duration.
3. Music: Your chosen audio track will fill the gap as an intro/outro if required.

You can also manually press "Fix duration" if required for more granular control.
