没有点击的Android语音输入

Question

我是Android开发的新手。我需要一个我正在开发的新应用程序的解决方案，它通过映射数据库进行语音输入和语音输出。当前程序通过onlick on按钮进行语音输入。我需要一个可以接受语音输入的灵魂，而无需点击任何与Talking Tom应用程序相似的按钮。这是我的代码。我的主要代码是 speakToMe ，这是onclick＆amp; amp;的 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");
