About

What OmniVoice is

OmniVoice GGUF GGUF weights for omnivoice.cpp, a C++17/GGML port of OmniVoice (k2-fsa/OmniVoice). Multilingual zero shot TTS, 646 languages, 24 kHz mono. Runs on CPU, CUDA, ROCm, Metal, Vulkan. Files Two GGUFs load together : omnivoice-base-{variant}.gguf Qwen3 0.6B backbone, text - tokens omnivoice-tokenizer-{variant}.gguf HuBERT + DAC + RVQ, tokens <- 24 kHz audio Quick start Backends Set GGMLBACKEND to force a device, otherwise the runtime picks the best one available. Quantization policy Tokenizer GGUFs are not uniform quants. Three categories get a dedicated treatment : Same fallback as llama.cpp tensortypefallback : F16 has no block size and matches the runtime target dtype on every backend. The base LM (Qwen3 0.6B, hidden = 1024) has all dimensions divisible by 256 so the fallback never triggers, the LM follows standard llama.cpp K-quant across variants. License Upstream model : OmniVoice by Xiaomi / k2-fsa, Apache 2.0 Audio codec : Higgs Audio v2 (bosonai/higgs-audio-v2-tokenizer), Apache 2.0 GGUF tooling : omnivoice.cpp, MIT

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys serveurperso-omnivoice for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (serveurperso-omnivoice below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/audio/transcriptions \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -F model="serveurperso-omnivoice" -F file=@audio.mp3
