Frequently Asked Questions

AI voice cloning uses deep learning to replicate a person's voice from a short audio sample. Once cloned, you can generate new speech that sounds like the original speaker. Modern models need as little as 5 seconds of reference audio.

ElevenLabs offers the best instant cloning from just 1 minute of audio with 29 language support. Azure Custom Neural Voice provides enterprise-grade voice creation. Cartesia Sonic also offers high-quality voice cloning with emotion control across 42 languages.

Most models work with 5-30 seconds of clear audio. Longer samples (up to 60 seconds) generally produce better results. The audio should be clean, single-speaker, without background music or noise.

You should only clone voices you have permission to use. This includes your own voice, voices from consenting individuals, or voices from properly licensed sources. Unauthorized voice cloning may violate laws in your jurisdiction.

Yes! Cross-lingual voice cloning providers like ElevenLabs (29 languages) and Cartesia Sonic (42 languages) can generate speech in different languages while maintaining the cloned voice identity. This is useful for dubbing and localization.

Creating a voice clone costs a flat 20 credits. Once cloned, using the voice for text-to-speech costs the same as any other voice on that model — 4 credits per 1,000 characters for premium models like ElevenLabs. Your cloned voice is stored in your account for unlimited reuse.

Record in a quiet environment with no background noise, echo, or music. Use a single speaker with natural, conversational speech. Avoid whispering or shouting. 10-60 seconds of clear audio is ideal. WAV or FLAC format is preferred over compressed MP3 for best clone quality.

There is no limit on the number of voices you can clone — each clone costs 20 credits. All cloned voices are saved to your account and can be managed from your account page. You can delete unused clones at any time to keep your voice library organized.

Yes. Use our API to programmatically clone voices and generate speech with cloned voices. Upload reference audio to the voice cloning endpoint to create a clone, then pass the returned voice ID to the TTS endpoint. Full API documentation with code examples is available on the API docs page.

Only clone voices with the speaker's explicit consent or your own voice. Never impersonate others for fraud, harassment, or deception. Many jurisdictions have laws protecting voice identity rights. WhatIsTTS prohibits using cloned voices for misleading or harmful content and may suspend accounts that violate these guidelines.

Instant voice cloning with ElevenLabs and Cartesia Sonic typically completes in 10-30 seconds. The processing time depends on the length of the reference audio and the provider. Once created, the cloned voice is immediately available for text-to-speech generation.

Yes, as long as you have the legal right to clone the voice. If it is your own voice, you can freely use it for commercial content including audiobooks, e-learning, marketing videos, and podcasts. For third-party voices, ensure you have written permission from the speaker.
