注意：在手機上必須選安裝文字轉語音引擎“google Text To Speech”
地址：http://www.shouji56.com/soft/GoogleWenZiZhuanYuYinYinQingGoogleTexttoSpeech_3864/
結果總結：
XE10.1 + 小米手機5 = 通過測試
首先手機上必須安裝語音包：
1.“google Text To Speech” (不知為什麼我的只發英文)
2.“度祕語音引擎3.0” (中英都可以發音)
3.“科大訊飛語音引擎3.0”(中英都可以發音)
4.APK發音使用的是當前語音包
5.小米手機5-設定-更多設定-語言和輸入法-文字轉語音（TTS）輸出
