java.lang.Object

io.github.ggerganov.whispercpp.WhisperCpp

All Implemented Interfaces:

AutoCloseable

public class WhisperCpp
extends Object

WhisperCpp

public WhisperCpp()

Method Details

modelDir

public File modelDir()

initContext

public void initContext(String modelPath)
                 throws FileNotFoundException

Parameters:

modelPath - - absolute path, or just the name (eg: "base", "base-en" or "base.en")

Throws:

FileNotFoundException

getFullDefaultParams

public WhisperFullParams getFullDefaultParams(WhisperSamplingStrategy strategy)

Provides default params which can be used with `whisper_full()` etc. Because this function allocates memory for the params, the caller must call either: - call `whisper_free_params()` - `Native.free(Pointer.nativeValue(pointer));`

Parameters:

strategy - - GREEDY

close

public void close()

Specified by:

close in interface AutoCloseable

fullTranscribe

public String fullTranscribe(WhisperFullParams whisperParams,
 float[] audioData)
                      throws IOException

Run the entire model: PCM -> log mel spectrogram -> encoder -> decoder -> text. Not thread safe for same context Uses the specified decoding strategy to obtain the text.

Throws:

IOException

getSystemInfo

public String getSystemInfo()

benchMemcpy

public int benchMemcpy(int nthread)

benchGgmlMulMat

public int benchGgmlMulMat(int nthread)
