Yes. We offer two levels of voice cloning. Our standard feature allows you to create a high-quality clone with just a 10-second audio sample. For those seeking even higher fidelity, we now offer Pro Voice Clones; by providing 30 minutes to a few hours of audio data, you can create a custom voice with unmatched quality and nuance.

Instant voice cloning enables you to create realistic digital replicas using just a few seconds of reference audio (typically 10 seconds). Depending on your subscription plan, you can clone up to 1,000 voices. Please note that explicit consent from the voice owner is required.

A Pro Voice Clone is a high-fidelity, hyper-realistic voice model created by fine-tuning our dedicated AI on a large dataset of your audio. Unlike standard cloning, this process captures the speaker's deepest emotional nuances, unique accents, and natural pacing, resulting in a digital voice indistinguishable from the original.

To get started, navigate to the Pro Voice Clone tab in Gradium Studio and upload your audio dataset. You will receive a notification once the upload is processed. After training is complete, the voice will appear in your library and be ready for Text-to-Speech (TTS) generation.

For an Instant Voice Clone, we get optimal results with only 10 seconds of data. For a Pro Voice Clone, we require a minimum of 30 minutes of clean audio data. For optimal results where the voice captures full emotional range and stability, we recommend providing 2 hours of audio.

Access to Pro Voice Clones is available to subscribers on Plan M and above.

Pro Voice Clones involve two costs: a one-time training fee of 1M credits and a usage rate of 1.2 credits per character. This rate reflects the resources required to train and run a fine-tuned model specific to your organization.

The audio data you provide is used strictly to train your specific voice model or generate your clone. This model remains isolated and is accessible only within your organization. For full details, please review our Privacy Policy and Terms of Service.
