如何开发类似talking tom的语音识别应用

Question

如何开发语音识别应用程序，像Talking？

 1. My request is how to recognize the voice without any events like buttons, touch events)

1. All语音记录示例包含通过按钮，但我的要求是在用户说话时识别语音录制语音，当用户停止语音时，它会自动修改其他语音中的语音，如Tom或parrot
2. 我已经通过button

完成了

我的.java

File storageDir = new File(Environment.getExternalStorageDirectory(), "SRAVANTHI");
storageDir.mkdir();
Log.d(APP_TAG, "Storage directory set to " + storageDir);
outfile = File.createTempFile("hascode", ".3gp", storageDir);

// init recorder
recorder.setAudioSource(MediaRecorder.AudioSource.MIC);
recorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB);
recorder.setOutputFile(outfile.getAbsolutePath());

// init player
player.setDataSource(outfile.getAbsolutePath());

try {
    recorder.prepare();
    recorder.start();
    recording = true;
} catch (IllegalStateException e) {
    Log.w(APP_TAG, "Invalid recorder state .. reset/release should have been called");
} catch (IOException e) {
    Log.w(APP_TAG, "Could not write to sd card");
}

recorder.stop();

用于播放按钮

try {
    playing = true;
    player.prepare();
    player.start();
} catch (IllegalStateException e) {
    Log.w(APP_TAG, "illegal state .. player should be reset");
} catch (IOException e) {
    Log.w(APP_TAG, "Could not write to sd card");
}

先检查音量，当音量超过一定值后再录音，怎么样？

也许这将是有用的：android: Detect sound level
