How much audio sample do I need?

A 15-second clear speech sample produces the best results. The sample should have minimal background noise and natural speaking pace.

How accurate is the voice clone?

F5-TTS captures tone, accent, and speaking rhythm very well. Results are convincing for most use cases, especially with high-quality samples.

Do I need to train a model?

No. F5-TTS uses zero-shot voice cloning. Just upload a sample and generate immediately — no model training or waiting required.

What can I use voice cloning for?

Custom voiceovers, audiobook narration, content creation, dubbing, and accessibility. Always use responsibly with consent.

How long can the generated speech be?

Up to about 30 seconds per generation. The total duration includes both the reference sample context and generated output.

What audio format is used?

Voice samples can be MP3, WAV, FLAC, OGG, or M4A. Output is high-quality WAV audio suitable for professional use.

Is there an ethical use policy?

Yes. Only clone voices you have permission to use. Never clone voices for impersonation, fraud, or without the speaker's consent.

How much does voice cloning cost?

Each generation costs 2 credits due to the complex voice analysis and synthesis. New accounts get free credits to try it.
