package com.megvii.idcardo2o.util;
    
    /** * 针对英文 */ import android.content.Context;
    import android.speech.tts.TextToSpeech;
    import java.util.Locale;
    
    public class SpeechUtils {
        private Context context;
        private static final String TAG = "SpeechUtils";
        private static SpeechUtils singleton;
    
        private TextToSpeech textToSpeech; // TTS对象
    
        public static SpeechUtils getInstance(Context context) {
            if (singleton == null) {
                synchronized (SpeechUtils.class) {
                    if (singleton == null) {
                        singleton = new SpeechUtils(context);
                    }
                }
            }
            return singleton;
        }
    
        public SpeechUtils(Context context) {
            this.context = context;
            textToSpeech = new TextToSpeech(context, new TextToSpeech.OnInitListener() {
                @Override
                public void onInit(int i) {
                    if (i == TextToSpeech.SUCCESS) {
                        textToSpeech.setLanguage(Locale.US);
                        // 设置音调，值越大声音越尖（女生），值越小则变成男声,1.0是常规
                        textToSpeech.setPitch(1.0f);
                        textToSpeech.setSpeechRate(1.0f);
                    }
                }
            });
        }
    
        public void speakText(String text) {
            if (textToSpeech != null) {
                textToSpeech.speak(text,
                        TextToSpeech.QUEUE_FLUSH, null);
            }
    
        }
    
    }

调用：SpeechUtils.getInstance(getApplicationContext()).speakText("hello world");

注意：此类只针对英文的播报！！！
