android 语音合成(文字转语音播放)

android自带

首先android自带文字转语音支持:TextToSpeech
但是在6.0之前不支持中文播放

 private TextToSpeech tts;
 private void play() {
        tts = new TextToSpeech(this,new listener());
    }
 private class listener implements TextToSpeech.OnInitListener {

        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
               //设置播放语言
                int result = tts.setLanguage(Locale.CHINESE);
                if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED){
                    Toast.makeText(VoiceActivity.this, "不支持", Toast.LENGTH_SHORT).show();
                }else if(result == TextToSpeech.LANG_AVAILABLE){
                  //初始化成功之后才可以播放文字
                  //否则会提示“speak failed: not bound to tts engine
                  //TextToSpeech.QUEUE_ADD会将加入队列的待播报文字按顺序播放
                  //TextToSpeech.QUEUE_FLUSH会替换原有文字
                  tts.speak("需要转化的文字",TextToSpeech.QUEUE_ADD,null);
                }
               
            } else {
                Log.e("TAG", "初始化失败");
            }

        }
    public void stopTTS() {
        if ( tts  != null) {
             tts .shutdown();
             tts .stop();
             tts = null;
        }
    }

科大讯飞语音合成

和其他第三方技术支持相同
1.注册,登录,申请应用
2.阅读文档,下载sdk,下载demo
3.语音合成步骤:

• 初始化,设置参数(发音人,大小,语速,)
• startSpeaking()
• 注意,这个并不支持添加多条文字,顺序播放,需要自己处理
• 遇到的问题:
  SpeechSynthesizer.createSynthesizer(this, this);等于null问题
  问题原因:因为android jar包默认路径是jniLibs,而我把包放入了libs里
  解决办法:build.gradle中加入下面代码:

sourceSets {
        main {
            jniLibs.srcDirs = ['libs']
        }
    }
