generate method

String generate(String audioBase64, String mediaType, [ String? optsJson ])

Transcribe audio to text.

audioBase64 — base64-encoded audio data. mediaType — media type of the audio (e.g. "audio/wav"). optsJson — optional serialized TranscriptionCallOptions. Returns the JSON-serialized TranscriptionResult, or throws on error.

Implementation

String generate(String audioBase64, String mediaType, [String? optsJson]) {
  _checkOpen();
  return _withUtf8(audioBase64, (audioPtr) {
    return _withUtf8(mediaType, (mediaPtr) {
      final optsPtr = optsJson != null ? optsJson.toNativeUtf8() : nullptr;
      try {
        final resultPtr =
            _ffi.transcriptionGenerate(_handle, audioPtr, mediaPtr, optsPtr);
        return _readResult(_ffi, resultPtr);
      } finally {
        if (optsPtr != nullptr) calloc.free(optsPtr);
      }
    });
  });
}
