vibevoice.cpp: Microsoft VibeVoice ported to ggml/C++ with no Python at inference

vibevoice.cpp: Microsoft VibeVoice (TTS + long-form ASR with diarization) ported to ggml/C++, runs on CPU/CUDA/Metal/Vulkan, no Python at inference

LocalAI released vibevoice.cpp, a ggml/C++ port of Microsoft VibeVoice for CPU, CUDA, Metal, and Vulkan inference. TTS uses a 30s reference clip for 24kHz cloned speech; ASR uses a 7B model with diarized JSON and was tested on 17min audio. The key constraint is memory: 17min CPU Q8_0 peaks near 26GB, with no streaming output yet.

Why it matters: HKR-H/K/R all pass: a practical open-source VibeVoice C++ port with concrete runtime numbers. Reddit-source scope and niche audio deployment keep it in the 72–77 featured band, not same-day must-write.
