대화없이 음성 인식을 프로그래밍하려고합니다. SpeechRecognizer.startListening(recognizerIntent)의 첫 번째 호출에 대해서는 모든 것이 잘 작동하며 인식 된 음성 문자열로 결과를 얻습니다. 그러나 두 번째 인식을 시작하려면 인식 시작 음만 재생하고 말하기를 중단하면 인식 종료 음을 들으십시오. onResults(), onRmsChanged 또는 onError 등과 같은 콜백 메소드는 호출되지 않습니다.SpeechRecognizer는 사운드를 재생하지만 startListening()을 호출 할 때 결과를 제공하지 않습니다.
