See examples/basic_use.rs for more details.
Lower level bindings are exposed if needed, but the above should be enough for most use cases. See the docs: https://docs.rs/whisper-rs/ for more details.
All disabled by default unless otherwise specified.

: expose whisper-rs-sys without having to pull it in as a dependency. NOTE: enabling this no longer guarantees semver compliance, as whisper-rs-sys may be upgraded to a breaking version in a patch release of whisper-rs.cuda
: enable CUDA support. Implicitly enables hidden GPU flag at runtime.hipblas
: enable ROCm/hipBLAS support. Only available on linux. Implicitly enables hidden GPU flag at runtime.opencl
: enable OpenCL support. Upstream whisper.cpp does not treat OpenCL as a GPU, so it is always enabled at runtime.openblas
: enable OpenBLAS support.metal
: enable Metal support. Implicitly enables hidden GPU flag at runtime.whisper-cpp-log
: allows hooking into whisper.cpp's log output and sending it to thelog
backend. Requires callingwhisper-cpp-tracing
: allows hooking into whisper.cpp's log output and sending it to thetracing
backend.
See BUILDING.md for instructions for building whisper-rs on Windows and OSX M1. Linux builds should just work out of the box.
- Something other than Windows/macOS/Linux isn't working!
- I don't have a way to test these platforms, so I can't really help you.
- If you can get it working, please open a PR with any changes to make it work and build instructions in BUILDING.md!
