安卓开发 - 使用 Android 原生TTS (TextToSpeech)

话不多说，直接上代码

private TextToSpeech textToSpeech;

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

		//创建 TextToSpeech 对象：在 Activity 中创建TextToSpeech对象，并传入OnInitListener监听器来监听初始化结果。
        textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    Log.d(TAG, "onInit: TTS初始化成功");
                    int result = textToSpeech.setLanguage(Locale.US);
                    if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                        // 语言不支持的处理
                        Log.d(TAG, "onInit: 当前设置的语言不支持哦");
                    }
                    speakOut("你好呀！");	//测试一下
                } else {
                    // TTS初始化失败
                    Log.d(TAG, "onInit: TTS初始化失败");
                }
            }
        });
        textToSpeech.setLanguage(Locale.CHINESE);   // 设置语言
        textToSpeech.setSpeechRate(0.6f);           // 设置语速
        textToSpeech.setPitch(1.2f);                // 设置音调
    }
	
	//朗读文本：调用speak方法来朗读文本。speak方法接受要朗读的文本、朗读队列模式和参数。
	public void speakOut(String text) {
        textToSpeech.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);
    }

	//释放资源：在onDestroy方法中停止朗读并关闭TextToSpeech对象，释放资源。
	@Override
    protected void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "onDestroy: ");
        if (textToSpeech!= null) {
            textToSpeech.stop();
            textToSpeech.shutdown();
        }
    }
