沒有點擊的Android語音輸入

Question

我是android開發新手。我需要一個針對正在開發的新應用程序的解決方案，該應用程序需要語音輸入並通過映射數據庫映射語音輸出。當前程序通過onlick按鈕進行語音輸入。我需要一個可以接受語音輸入而不需要點擊與Talking Tom應用程序相似的任何按鈕的精靈。這裏是我的code.My主要代碼是speakToMe這是方法要求的onclick & onActivityResult

Answer 1

Voice Recognition not working for talking tom app so you try to use noise detection with sound meter. below here link for voice/ noise detection with audio recording without click.

Please change SoundMeter.java File 

mRecorder.setOutputFile(Environment.getExternalStorageDirectory(). 
        getAbsolutePath() + "/test.3ggp");
