zero-shot voice cloning
One short sample is enough to create a usable cloned voice.
- Clone from a 10-30 second clean sample
- Self-serve via API or Console
- Good quality tier
- Consent required
definition
Zero-shot voice cloning creates a usable voice from a single short sample, with no separate training run. You provide 10 to 30 seconds of clean speech and a consent record on the Speechify Build API, and you get a voice ID back to synthesize with. It is the fast, self-serve path to a clone.
how-it-works
The model clones directly from the sample rather than fine-tuning on a large dataset. That is what makes it instant and self-serve: send the sample, get the voice ID, synthesize. The trade is quality tier, zero-shot is good quality, where fine-tuning reaches the best.
the-sample
Results track the sample. Aim for 10 to 30 seconds of clean speech, under a minute and under 5MB, with no background noise. A clean sample is the single biggest factor in a good zero-shot clone.
consent
A consent record with the speaker’s full name and email is required to create the voice, zero-shot included. See instant cloning for the product view and fine-tuned cloning for the higher tier.
