제목이 분명하지 않다고 생각합니다. 내 프로젝트에서 나는 백그라운드에서 실행되는 서비스를 원하고 사용자가 "hello phone"또는 일부 단어/문구를 말할 때 내 앱이 음성을 인식하기 시작합니다. 실제로 그것은 작동하지만 옳은 길은 아닙니다 ... 나는 서비스를 가지고 있으며이 서비스는 음성을 감지합니다.SpeechRecognitionService (단어 인식 포함)

그리고 난 내 MainActivity에서 서비스를 시작 단지 시도 :
Intent i = new Intent(context, SpeechActivationService.class);
startService(i);
이 너무 많이 음성 입력을 감지 ... 그리고! 그것이 무언가를 발견 할 때마다 그것은 "bipbip"입니다. 너무 많은 bips !! 실망 스럽습니다. 나는 "hello phone"이나 "start"또는 특정 단어를 말할 때만 시작하기를 원합니다 !! 이 https://github.com/gast-lib/gast-lib/blob/master/library/src/root/gast/speech/activation/WordActivator.java을 보려고하지만 실제로이 라이브러리를 어떻게 사용하는지 모르겠습니다. 나는이 질문을보십시오 onCreate of android service not called하지만 정확히 무엇을 해야할지 이해하지 못한다. 어쨌든, 나는 이미 gast 라이브러리를 가져온다. 나는 단지 그것을 사용하는 방법을 알 필요가있다. 누구든지 나를 도와 줄 수 있습니까? 감사합니다
