whisper.cpp is a plain C/C++ implementation of OpenAI's Whisper automatic
speech recognition model, built on the ggml tensor library and free of
external runtime dependencies. It transcribes and translates audio using
quantized models in the GGML format, on CPU or with optional acceleration
through CUDA, ROCm/HIP, Vulkan or OpenCL backends.
The package provides whisper-cli (one-shot transcription), whisper-server
(an HTTP server with an OpenAI-compatible endpoint), whisper-bench and
whisper-quantize, plus the parakeet-cli and parakeet-quantize tools for
NVIDIA's Parakeet TDT models, which upstream added alongside Whisper in the
1.9 series. With USE=sdl2 the real-time microphone examples whisper-stream,
whisper-command, whisper-talk-llama and whisper-lsp are built as well.
Models are not shipped with this package and must be downloaded separately,
typically from Hugging Face. The CPU backend is tuned through the
architecture's CPU_FLAGS: on x86 through CPU_FLAGS_X86, and on ARM through
CPU_FLAGS_ARM, which ggml gates at compile time via an accumulated -march
string rather than per-feature build options.
The ggml libraries this package builds are installed into a private
subdirectory rather than the system libdir, because sci-ml/llama-cpp
vendors the same ggml tree and owns those paths.
Note that the ebuild is adapted from the istitov/stuff overlay
(app-accessibility/whisper-cpp).
