android自帶

首先android自帶文字轉(zhuǎn)語音支持: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) {
               //設(shè)置播放語言
                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
                  //否則會提示“speak failed: not bound to tts engine
                  //TextToSpeech.QUEUE_ADD會將加入隊列的待播報文字按順序播放
                  //TextToSpeech.QUEUE_FLUSH會替換原有文字
                  tts.speak("需要轉(zhuǎn)化的文字",TextToSpeech.QUEUE_ADD,null);
                }
               
            } else {
                Log.e("TAG", "初始化失敗");
            }

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

科大訊飛語音合成

https://www.xfyun.cn/
和其他第三方技術(shù)支持相同
1.注冊,登錄,申請應(yīng)用
2.閱讀文檔,下載sdk,下載demo
3.語音合成步驟:

• 初始化,設(shè)置參數(shù)(發(fā)音人,大小,語速,)
• startSpeaking()
• 注意,這個并不支持添加多條文字,順序播放,需要自己處理
• 遇到的問題:
  SpeechSynthesizer.createSynthesizer(this, this);等于null問題
  問題原因:因為android jar包默認路徑是jniLibs,而我把包放入了libs里
  解決辦法:build.gradle中加入下面代碼:

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