如何开发像汤姆汤姆一样的语音识别应用程序

Question

如何开发像Talking Tom这样的语音识别应用程序？
1.我的要求是如何在没有按钮,触摸事件等任何事件的情况下识别语音
.2.所有录音样本都包含通过按钮,但我的要求是当用户在该时间讲话时识别语音并且当用户自动停止语音时用汤姆或鹦鹉
3 等其他声音修改声音.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();

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，超过一定值才录音怎么样？

也许这会有用： android: Detect sound level
