I am doing speech recognition using a third party cloud service on Android, and it works well with Android API SpeechRecognizer. Code below:
Intent recognizerIntent =
new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);
// accept partial results if they come
recognizerIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
//need to have a calling package for it to work
if (!recognizerIntent.hasExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE)) {
recognizerIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "com.example.speechrecognition");
}
recognizer = SpeechRecognizer.createSpeechRecognizer(context);
recognizer.setRecognitionListener(this);
recognizer.startListening(recognizerIntent);
At the same time, I want to record the audio with different audio setting, such as frequency, channels, audio-format, etc. Then I will continuously analyze this audio buffer. I use the AudioRecord for the purpose. This works well only I turn off the speech recognition.
If I record audio and speech recognition at the same time, then error happens.
E/AudioRecord: start() status -38
How to implement this kind of feature, I also tried native audio - SLRecordItf, also doesn't work.
