SuperClonica offers the same kind of building block that runs on your own machine.\n\nThis page compares the two setups honestly, says when a cloud API is the better choice, and shows how to swap a cloud call for a local one.","sections":[{"heading":"Cloud API vs a voice you run","points":["Cloud TTS: managed servers, many languages and voices, billing by usage, your text sent to the provider.","SuperClonica: a Docker image with an HTTP endpoint, a Python library and a command-line tool, all running locally.","After the one-time model download, about 385 MB, the server needs no internet.","Voices are JSON files: the ten built-in voices, catalog voices, or a voice trained from your own recording."],"paragraphs":["Cloud APIs are easier to start and scale to any load; a local engine trades that for privacy and a fixed cost."]},{"heading":"When a cloud API is the better choice","paragraphs":["Choose a cloud API when you need Chinese or a very long list of languages and regional variants, SSML control, managed scaling with service guarantees, or simply no server to maintain. SuperClonica speaks 31 languages, has no SSML and runs on hardware you manage."]},{"heading":"When SuperClonica fits better","points":["Your texts are private: medical notes, internal documents, unreleased game dialogue.","You need to work offline or inside a closed network.","Your volume is large or unpredictable, and a per-character bill would grow with it.","You want character voices, a brand voice trained from your own speaker, and the same voice in all 31 languages."],"paragraphs":["In our tests a short phrase took 0.12 s on an RTX 5070 Ti and 0.43 s on four threads of a Ryzen 7 5800X."]},{"heading":"Swap the API call","paragraphs":["Start the server on any CPU: docker run -d --name tts -p 8000:8000 -v superclonica-models:/models superclonica/superclonica:cpu.

POST /synthesize takes text, voice, lang, seed and normalize and answers with a 16-bit mono WAV file. Set SUPERCLONICA_API_KEY to require an Authorization header, and keep the server behind HTTPS or on a private network. A custom voice goes into the request as its JSON object."]},{"heading":"Costs and licenses","paragraphs":["The SuperClonica engine and the Docker image are released under the Apache License 2.0. The Supertonic 3 model is under OpenRAIL-M, a royalty-free license that allows commercial use within its list of prohibited uses. The built-in voices and several catalog voices are free; other catalog voices are bought once. Check the cloud providers’ current prices on their own sites before you compare."]}],"faq":[{"question":"Is it a drop-in replacement for Google’s API?","answer":"No. The request format is different and simpler: POST /synthesize with text, voice and lang. There is no SSML."},{"question":"Does it support Chinese?","answer":"Not yet. Supertonic 3 speaks 31 languages, and Chinese is not among them."},{"question":"Does the server need a GPU?","answer":"No. The cpu image runs on any processor; the cuda image uses an NVIDIA GPU for more speed."},{"question":"Can I use it commercially?","answer":"The engine is Apache 2.0 and the model is OpenRAIL-M, which allows commercial use within its use restrictions.
