Overview

What is VieNeu-TTS?

A Vietnamese, with English code-switching, text-to-speech system with instant zero-shot voice cloning from a few seconds of reference audio. The current v3 Turbo is a 0.1B model trained from scratch on around 10,000 hours of Vietnamese-English speech, outputs 48 kHz and uses the MOSS-Audio-Tokenizer-Nano codec, with a Python package, CPU (ONNX/GGUF) and GPU paths and Docker serving.

Analysis

Pros & Cons

Pros

  • Fills a genuine niche: dedicated, open, voice-cloning Vietnamese TTS with code-switching, poorly covered by mainstream open models
  • Apache-2.0 on code and weights, commercial-safe with no inherited restrictions
  • A real on-device CPU path (torch-free ONNX/GGUF) plus pip and Docker tooling

Cons

  • The flagship v3 Turbo is 'early access', not a final release, so the strongest claims sit on a pre-stable build
  • Language scope is narrow (Vietnamese and English only)
  • Largely single-maintainer; long-term support and the from-scratch training claims rest on the author's statements
License

License

Apache-2.0 (OSI-open) - model license: Apache-2.0

Both the code and the model weights are Apache-2.0; v3 Turbo is trained from scratch, so there is no inherited base-model restriction.

When it is interesting

You specifically need offline, commercially licensed Vietnamese voice cloning or Vietnamese-English code-switching on CPU or a modest GPU.

When it is too early

If you need a frozen, production-stable release today; use the stable v1/v2 rather than v3 Turbo early access.
