L_ASRRecognizer_AcceptWaveformData

Summary

Feeds waveform samples into the transcribing engine. The samples should be 16-bit, mono, and at 16Khz or 8Khz sample rate.

Syntax

#include "ltasr.h"

L_LTASR_API L_INT L_ASRRecognizer_AcceptWaveformData(recognizer, data, endPointDetected)

Parameters

const L_ASRWaveformData *data

Pointer to a structure represents the audio data from the live source.

L_BOOL *endPointDetected

When L_TRUE, it means silence or safe stopping point has been detected. This means subsequent audio samples feed will not cause the former text to be modified or updated.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

At endPointDetected = L_TRUE, you can safely call L_ASRRecognizer_GetResult() to acquire whatever text was transcribed up to this point. Calling L_ASRRecognizer_GetResult() will free up the memory as if restarting the process all over again. When endPointDetected = L_FALSE, you may call L_ASRRecognizer_GetPartialResult() to peek into the temporary results the engine has.
