Voice Cloning API
Free to start. No card needed.
A REST API to create voice clones and generate speech from them, gated to Pro and up — rate limits, points cost, and what it does for developers.
Sound tags work on every plan. Written directions use the VocalLab Studio model on Pro. See plans

“I sent it off to 5 people (including my husband) without any context and asked for their objective feedback. … not a single person questioned if it was truly me/my voice.”
“I've tried voice cloning on several other apps and none of them came this close. VocalLab got my voice to a T.”

About this tool
Everything you need to know about Voice Cloning API
The voice cloning API is a REST interface that creates clones and generates speech from them programmatically, so an application can do everything the product UI does without a person clicking through it. It's gated to Pro and above: 60 requests per minute on Pro, 120 on Max, and it bills the same way generation always does — about one point per second of speech, nothing extra for the API call itself. Cloning still costs no points; only generation does.

What plan do I need to get API access to voice cloning?
The API is gated to Pro and above, so a Free or Lite account can clone and generate in the product but can't call the API directly.
What are the actual rate limits?
60 requests per minute on the baseline tier that has API access, rising to 120 requests per minute on the Max plan.
Does creating a clone through the API cost points?
No, creating a clone is free of points through the API just as it is in the product — points are spent only when you generate audio.
How is a generation call billed?
The same way it's billed in the product, roughly one point per second of speech, calculated from the character count of the text sent.
