Rust bindings to whisper.cpp
```rust fn main() { // load a context and model let mut ctx = WhisperContext::new("path/to/model").expect("failed to load model");
// create a params object
let mut params = FullParams::new(DecodeStrategy::Greedy { n_past: 0 });
// assume we have a buffer of audio data
// here we'll make a fake one, floating point samples, 32 bit, 16KHz, mono
let audio_data = vec![0_f32; 16000 * 2];
// now we can run the model
ctx.full(params, &audio_data[..])
.expect("failed to run model");
// fetch the results
let num_segments = ctx.full_n_segments();
for i in 0..num_segments {
let segment = ctx.full_get_segment_text(i).expect("failed to get segment");
let start_timestamp = ctx.full_get_segment_t0(i);
let end_timestamp = ctx.full_get_segment_t1(i);
println!("[{} - {}]: {}", start_timestamp, end_timestamp, segment);
}
} ```
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.
By default, you will experience a vague error from rustc about not being able to "find native static library `whisper`"
To resolve this, you need to clone the original whisper.cpp repo and build it. Then, set RUSTFLAGS to point to the built library.
You also need to link against the C++ standard library, which can be done with the -lstdc++ flag.

git clone https://github.com/ggerganov/whisper.cpp
cd whisper.cpp
make libwhisper.a

tl;dr: public domain
