Frequently asked questions

Can ESpeech-TTS be used in a commercial project?

With conditions. License: Apache 2.0 according to the HF model card; the model is built on the F5-TTS architecture, whose official weights are non-commercial, so check with a lawyer before commercial launch. Restrictions vary — region, company revenue, attribution requirements. Have a lawyer check the terms before a commercial launch.

What hardware does ESpeech-TTS need?

At minimum: Laptop or regular PC, up to 8 GB of VRAM — smaller versions. Without a GPU the model is not practical. You can calculate the exact VRAM for your model size and context in the hardware calculator.

Does ESpeech-TTS support Russian?

Yes, Russian is listed on the model card.

Where can I download ESpeech-TTS and what does it cost?

The ESpeech-TTS weights are open and free to download. You only pay for the hardware it runs on and for the setup. Source links are at the bottom of this page.
