whisper-rs

Rust bindings to whisper.cpp

Usage

git clone --recursive https://github.com/tazz4843/whisper-rs.git

cd whisper-rs

cargo run --example basic_use

cargo run --example audio_transcription
use whisper_rs::{WhisperContext, WhisperContextParameters, FullParams, SamplingStrategy};

fn main() {
	let path_to_model = std::env::args().nth(1).unwrap();

	// load a context and model
	let ctx = WhisperContext::new_with_params(
		path_to_model,
		WhisperContextParameters::default()
	).expect("failed to load model");

	// create a params object
	let params = FullParams::new(SamplingStrategy::Greedy { best_of: 1 });

	// 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
	let mut state = ctx.create_state().expect("failed to create state");
	state
		.full(params, &audio_data[..])
		.expect("failed to run model");

	// fetch the results
	let num_segments = state
		.full_n_segments()
		.expect("failed to get number of segments");
	for i in 0..num_segments {
		let segment = state
			.full_get_segment_text(i)
			.expect("failed to get segment");
		let start_timestamp = state
			.full_get_segment_t0(i)
			.expect("failed to get segment start timestamp");
		let end_timestamp = state
			.full_get_segment_t1(i)
			.expect("failed to get segment end timestamp");
		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.

Feature flags

All disabled by default unless otherwise specified.

Building

See BUILDING.md for instructions for building whisper-rs on Windows and OSX M1. Linux builds should just work out of the box.
