Detailed Description

Example:

OnlineRecognizer recognizer = OnlineRecognizer::Create(config);
OnlineStream stream = recognizer.CreateStream();
stream.AcceptWaveform(wave.sample_rate, wave.samples.data(),
                      wave.samples.size());
stream.InputFinished();
while (recognizer.IsReady(&stream)) {
  recognizer.Decode(&stream);
}
auto result = recognizer.GetResult(&stream);
