whisper-rs

Rust bindings to whisper.cpp

Usage

```rust use whisper_rs::{WhisperContext, FullParams, SamplingStrategy};

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(SamplingStrategy::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.

Building

See BUILDING.md for instructions for building whisper-rs on Windows and OSX M1.

Troubleshooting

• I get an error about a lot of undefined symbols at compile time!
  • These symbols might be part of the C++ standard library.
  • Try linking against it with the -Clink-args=-lstdc++ compiler flag:
  • RUSTFLAGS="-Clink-args=-lstdc++" cargo build
• macOS/Android aren'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!
• I get a panic during binding generation build!
  • You can attempt to fix it yourself, or you can set the WHISPER_DONT_GENERATE_BINDINGS environment variable. This skips attempting to build the bindings whatsoever and copies the existing ones. They may be out of date, but it's better than nothing.
  • WHISPER_DONT_GENERATE_BINDINGS=1 cargo build
  • If you can fix the issue, please open a PR!
