Struct WhisperContext 

pub struct WhisperContext { /* private fields */ }

Implementations

impl WhisperContext

pub fn new<P: AsRef<Path>>(model_path: P) -> Result<Self>

pub fn new_from_buffer(buffer: &[u8]) -> Result<Self>

pub fn is_multilingual(&self) -> bool

pub fn n_vocab(&self) -> i32

pub fn n_audio_ctx(&self) -> i32

pub fn n_text_ctx(&self) -> i32

pub fn n_len(&self) -> i32

impl WhisperContext

pub async fn transcribe_async(&self, audio: Vec<f32>) -> Result<String>

Transcribe audio asynchronously using default parameters

pub async fn transcribe_with_params_async( &self, audio: Vec<f32>, params: TranscriptionParams, ) -> Result<TranscriptionResult>

Transcribe audio asynchronously with custom parameters

pub async fn create_state_async(&self) -> Result<WhisperState>

Create an async state for manual control

impl WhisperContext

pub fn transcribe(&self, audio: &[f32]) -> Result<String>

Transcribe audio using default parameters

Arguments

• audio - Audio samples (must be 16kHz mono f32)

Returns

The transcribed text as a string

Example

let ctx = WhisperContext::new("model.bin")?;
let audio = vec![0.0f32; 16000]; // 1 second
let text = ctx.transcribe(&audio)?;

pub fn transcribe_with_params( &self, audio: &[f32], params: TranscriptionParams, ) -> Result<TranscriptionResult>

Transcribe audio with custom parameters

Arguments

• audio - Audio samples (must be 16kHz mono f32)
• params - Custom transcription parameters

Returns

A TranscriptionResult containing the full text and individual segments

pub fn transcribe_with_full_params( &self, audio: &[f32], params: FullParams, ) -> Result<TranscriptionResult>

Transcribe audio with full control over parameters

Arguments

• audio - Audio samples (must be 16kHz mono f32)
• params - Full parameter configuration

Returns

A TranscriptionResult containing the full text and individual segments

pub fn create_state(&self) -> Result<WhisperState>

Create a new state for manual transcription control

This allows you to reuse a state for multiple transcriptions, which can be more efficient than creating a new state each time.

pub fn transcribe_with_params_enhanced( &self, audio: &[f32], params: TranscriptionParams, ) -> Result<TranscriptionResult>

Enhanced transcription with custom parameters and temperature fallback

This method provides quality-based retry with multiple temperatures if the initial transcription doesn’t meet quality thresholds.

Arguments

• audio - Audio samples (must be 16kHz mono f32)
• params - Custom transcription parameters

Returns

A TranscriptionResult containing the full text and individual segments

Example

let ctx = WhisperContext::new("model.bin")?;
let params = TranscriptionParams::builder()
    .language("en")
    .build();
let audio = vec![0.0f32; 16000];
let result = ctx.transcribe_with_params_enhanced(&audio, params)?;

pub fn transcribe_with_full_params_enhanced( &self, audio: &[f32], params: FullParams, ) -> Result<TranscriptionResult>

Enhanced transcription with full parameters and temperature fallback

This method provides quality-based retry with multiple temperatures if the initial transcription doesn’t meet quality thresholds.

Arguments

• audio - Audio samples (must be 16kHz mono f32)
• params - Full parameter configuration

Returns

A TranscriptionResult containing the full text and individual segments

Trait Implementations

impl Clone for WhisperContext

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
