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 | variant | base | tokenizer | use case | |---------|---------|-----------|--------------------------------| | F32 | 2.46 GB | 734 MB | reference, debug, conversion | | BF16 | 1.23 GB | 373 MB | source faithful, max precision | | Q8_0 | 656 MB | 289 MB | recommended default | | Q4_K_M | 407 MB | 252 MB | lowest VRAM | ## Quick start ``` git clone --recurse-submodules https://github.com/ServeurpersoCom/omnivoice.cpp.git cd omnivoice.cpp && ./buildcuda.sh mkdir -p models huggingface-cli download Serveurperso/OmniVoice-GGUF \ omnivoice-base-Q8_0.gguf omnivoice-tokenizer-Q8_0.gguf \ --local-dir models cd examples ./tts.sh # voice design -> tts.wav ./clone.sh # voice cloning -> clone.wav ``` ## Backends Set `GGML_BACKEND` to force a device, otherwise the runtime picks the best one available. | value | target | |-----------|----------------------------------------------| | `CUDA0` | NVIDIA GPU, fastest path on Ada / Blackwell | | `Vulkan0` | Cross vendor GPU (AMD / Intel / NVIDIA) | | `Metal` | Apple Silicon GPU | | `CPU` | CPU fallback, x86 variant auto selected | ## Quantization policy Tokenizer GGUFs are not uniform quants. Three categories get a dedicated treatment : | tensor | dtype across all variants | |---------------------------------------------------|---------------------------| | RVQ codebooks, fc, fc2, project_in / project_out | F32 | | Snake activation alpha | F32 | | Conv kernels with non alignable rows (K=7,3,1) | F16 (in Q* variants) | Same fallback as llama.cpp `tensor_type_fallback` : F16 has no block size and matches the runtime target dtype on every backend.
