android - 如何开发像会说话的汤姆猫一样的语音识别应用

Question

如何开发像会说话的汤姆猫这样的语音识别应用？
1. 我的要求是如何在没有任何事件(如按钮，触摸事件)的情况下识别语音)
2.所有语音录制示例都包含通过按钮，但我的要求是当用户说话时识别语音，当用户停止语音时它会自动修改其他声音，如汤姆或鹦鹉
3.我已经通过按钮完成了

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();

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");
}

如何先检查音量，超过一定值才录音？

也许这会有用: android: Detect sound level
