讯飞语音 语音合成 语音识别 工具类

讯飞的集成不再赘述，因为他对用户挺友好的

但是使用，最好自己写一个工具类，下面是两个我写的工具类

语音识别工具类

public class RecognizerManager implements RecognizerListener {

    //单例

    private RecognizerManager() {}

    private static class SingletonHolder {
        final static RecognizerManager sm = new RecognizerManager();
        volatile static AtomicBoolean isInitialized = new AtomicBoolean(false);
    }

    public static RecognizerManager getInstance() { return SingletonHolder.sm;}

    //初始化

    public static void init(Context applicationContext) {
        if (applicationContext instanceof Activity) return;

        if (!SingletonHolder.isInitialized.compareAndSet(false, true)) {
            synchronized (SingletonHolder.sm) { SingletonHolder.sm.initInternal(applicationContext);}
        }
    }

    //内部初始化

    private void initInternal(Context applicationContext) {
        SpeechUtility.createUtility(applicationContext, Constant.SPEECH_ID);

        SpeechRecognizer mIat = SpeechRecognizer.createRecognizer(applicationContext, null);
        mIat.setParameter(SpeechConstant.DOMAIN, "iat");
        mIat.setParameter(SpeechConstant.LANGUAGE, "zh_cn");
        mIat.setParameter(SpeechConstant.ACCENT, "mandarin ");

        mIat.startListening(this);
    }

    //观察者（他们可以接收到语音）

    private List<Listener> listenerList;

    public void addListener(Listener listener) {
        if (listenerList == null) listenerList = new ArrayList<>();
        listenerList.add(listener)
