No Hugging Face login, hosted demo, or original Supertone service is\nrequired. These instructions use Supertonic 3.\n\n---\n\n### 1. Clone the source and install the download tool\n\nUse Python 3.11 in a virtual environment:\n\n```bash\ngit clone https://github.com/supertone-oss-archive/supertonic.git\ncd supertonic\npython3.11 -m venv .venv\nsource .venv/bin/activate\npython -m pip install huggingface_hub\n```\n\nOn Windows, activate the environment with `.venv\\Scripts\\Activate.ps1` in PowerShell.\n\n---\n\n## Getting Started in Other Runtimes\n\nDownload the same `assets/` directory from the repository root before running\nthe examples below. The language examples read these local files.\n\nSome language examples need native runtimes:\n- **Go**: install the ONNX Runtime C library. On macOS, `brew install onnxruntime`.\n- **Java**: use a JDK, not just a JRE. On macOS, `brew install openjdk@17`.\n- **C#**: targets .NET 9 and allows major-version roll-forward.\n\n---\n\n## License\n\nThis project's sample code is released under the MIT License. - see the [LICENSE](./LICENSE) for details.\n\nThe accompanying model is released under the OpenRAIL-M License. - see the [LICENSE](https://huggingface.co/supertone-oss-archive/supertonic-3/blob/main/LICENSE) file for details.\n\nThis model was trained using PyTorch, which is licensed under the BSD 3-Clause License but is not redistributed with this project. - see the [LICENSE](https://docs.pytorch.org/FBGEMM/general/License.html) for details.\n\nCopyright (c) 2026 Supertone Inc.","github_created_at":"2025-11-18T08:23:58+00:00","created_at":"2026-07-11T12:04:34.710802+00:00","updated_at":"2026-09-20T07:03:45.844511+00:00","categories":[{"slug":"speech-audio","name":"Speech & Audio","url":"https://www.graphcanon.com/categories/speech-audio","markdown_url":"https://www.graphcanon.com/categories/speech-audio.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/speech-audio"}],"tags":[{"slug":"cpp","name":"cpp"},{"slug":"csharp","name":"csharp"},{"slug":"flutter","name":"flutter"},{"slug":"go","name":"go"},{"slug":"ios","name":"ios"},{"slug":"java","name":"java"},{"slug":"lightweight","name":"lightweight"},{"slug":"multilingual","name":"multilingual"}],"trust":{"provenance":{"is_fork":false,"github_id":1098852899,"owner_type":"Organization","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-09-20T07:03:43.609Z","maintenance":{"label":"Archived","score":8,"methodology":"github_public_v1","releases_90d":0,"days_since_push":11,"last_release_at":"2026-01-06T08:16:41Z","stars_delta_30d":242,"open_issues_delta_30d":5},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T12:04:44.485Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"scan":{"source":"repo_scan","observed_at":"2026-09-20T07:03:45.082Z"},"languages":{"value":["swift"],"source":"github.language","observed_at":"2026-09-20T07:03:45.082Z"},"license_spdx":{"value":"MIT","source":"github.license","observed_at":"2026-09-20T07:03:45.082Z"}},"decision_facts":{"hosting":null,"pricing":null,"requirements":null,"constraints":null,"when_to_use":["When deploying text-to-speech functionality requires swift performance on-device in multiple languages","For projects that need native Swift integration for iOS applications"],"when_not_to_use":["If the application is multilingual but does not require on-device processing capabilities","For teams preferring a different primary development language other than Swift or those lacking familiarity with ONNX implementation details"],"source":"enrich:decision_facts","observed_at":"2026-07-17T07:11:52.171Z"},"constraint_facets":null,"decision_summary":[{"label":"Adopt for","value":"Supertonic provides fast multilingual TTS on-device using ONNX runtime, native to Swift with wide language support."}]}}
