如何在android模块中将胡椒文本转换为语音速度？

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

private TextToSpeech textToSpeech;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                // 设置语言为英语
                int result = textToSpeech.setLanguage(Locale.ENGLISH);

                if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                    Log.e("TTS", "Language not supported");
                }
            } else {
                Log.e("TTS", "Initialization failed");
            }
        }
    });
}

@Override
protected void onDestroy() {
    if (textToSpeech != null) {
        textToSpeech.stop();
        textToSpeech.shutdown();
    }
    super.onDestroy();
}

String text = "Hello, World!";
textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null);
