Professional Voice Cloning
Fine-tune a highly similar, stable voice clone from a larger set of audio samples
Professional Voice Cloning is currently in beta.
Professional Voice Cloning produces a voice clone that's more similar to the original speaker and more stable than Instant Voice Cloning, in exchange for more audio and an asynchronous training step instead of an instant result.
To get started, create a Professional Voice Clone through Inworld Portal. Go to TTS Playground > Create Voice > Professional Clone and follow the guided flow.
Create a Professional Voice Clone in Portal
Choose Create Voice
In Portal, select TTS Playground from the left-hand side panel. In the TTS Playground, click Create Voice.
Select Professional Clone
On the Create Voice page, select Professional Clone.
Name your voice
Enter a Voice name. Description and tags are optional.
Only English is currently supported for Professional Voice Cloning.
Upload audio samples and start training
Click Add Audio to upload your audio samples.
- You can upload multiple audio files, up to a combined limit of 5GB.
- Uploaded audio must total at least 10 minutes combined. More clean, high-quality audio generally produces a better clone.
Enable Remove background noise if you wish to remove background noise from your audio. Confirm you have the rights to clone the voice, then click Start Training.
Check out our Voice Cloning Best Practices for tips on recording and preparing audio for a professional voice clone.
Wait for training to complete
Once training starts, you can leave the page — training continues in the background and can take several minutes for longer samples.
Training status is displayed on the Voices page, where your request appears under Professional clone requests along with its current status.
Use your voice from My Voices
Once training finishes, the voice moves to My voices, ready to use in the TTS Playground or via the TTS API. To use it via the TTS API, copy the voice ID and use that value for the voiceId when making an API call. See our Quickstart to learn how to make your first TTS API call.
