Audio8 TTS 0.1B ONNX INT8
Audio8 TTS 0.1B ONNX INT8 packages a compact multilingual text-to-speech model for CPU inference through ONNX Runtime, including zero-shot voice cloning.
The downloadable package combines INT8 speech-generation models with an FP16 audio codec. Audio8's separate runtime adds local voice registration, command-line use, streaming, and HTTP and OpenAI-compatible speech endpoints. Use this as a first read, not a recommendation. Open the original project before trusting details like terms, limits, privacy, cost, setup, or safety.
What it is
Compact multilingual speech generation
The package turns text into 44.1 kHz mono speech and supports a packaged default voice or a registered reference voice across 11 recommended languages.
Why it stands out
A small CPU service, not only model files
Audio8 reports about 0.6 GB for the loaded speech-generation sessions in its test setup. The runtime can expose the model through a local web interface, HTTP API, or OpenAI-compatible speech endpoint without requiring CUDA.
Availability
Model files and runtime are separate
Hugging Face hosts the ONNX model package. Inference, streaming, and voice-registration code live in Audio8's GitHub repository, with current setup notes for macOS arm64 and Linux x86_64.
Why it matters
What makes it useful
A local TTS model becomes easier to put inside an app when the runtime already handles voice registration, streaming, and familiar speech APIs. The reported memory footprint also makes testing practical on CPU-only machines that cannot spare a large GPU setup.
What to know
Where it fits
Use it as a local speech-output layer for prototypes, assistants, narration tools, or other applications that can call an HTTP speech endpoint. It is a preview model package rather than a finished voice product, so the surrounding app still owns text handling, user controls, storage, and disclosure.
Notable points
What stands out
Audio8 reports about 0.6 GB after loading the sessions used for normal speech generation in its test setup. The complete model repository is about 1 GB because it also includes the encoder used to register reference voices. Actual memory use varies by platform and runtime.
Before using
What to review
The documented ONNX path requires Python 3.11 or newer and is currently tested on macOS arm64 and Linux x86_64. Other systems may need additional work.
Audio8 recommends a 0.5 to 30 second reference recording with an exact transcript for voice registration. Noisy, long, or incorrectly transcribed references can reduce stability and speaker similarity.
INT8 quantization can change generated token sequences. Test the exact language, voice, text length, and deployment settings instead of assuming the same output as the source checkpoint.
The linked ONNX package and base checkpoint do not currently present one consistent license label. Review the current terms at the source and ask Audio8 if the intended use depends on them.
Obtain consent before cloning another person's voice, and clearly disclose synthetic speech where the context calls for it.
Reader fit
Who may find it relevant
Builders who want a compact local TTS service that can run through ONNX Runtime on a CPU.
People testing multilingual speech or reference-voice registration behind a familiar HTTP API.
Less relevant for readers who need a polished consumer app, verified performance on Windows, or settled license terms before evaluation.
Editorial note
Why LifeHubber lists it
LifeHubber lists this Audio8 package because it turns a compact voice-cloning model into a CPU-ready local service with voice registration and familiar speech endpoints. That helps builders decide whether a small self-run TTS layer is enough before taking on a heavier deployment stack.
