C#實(shí)現(xiàn)文字轉(zhuǎn)語(yǔ)音功能

第C#實(shí)現(xiàn)文字轉(zhuǎn)語(yǔ)音功能本文實(shí)例為大家分享了C#實(shí)現(xiàn)文字轉(zhuǎn)語(yǔ)音的具體代碼，供大家參考，具體內(nèi)容如下

客戶(hù)提出要求，將文字內(nèi)容轉(zhuǎn)為語(yǔ)音，因?yàn)閮?nèi)網(wǎng)環(huán)境，沒(méi)辦法采用聯(lián)網(wǎng)，在線(xiàn)這種方式，靈機(jī)一動(dòng)，能否寫(xiě)一個(gè)簡(jiǎn)單的例子呢，搜索相關(guān)資料還真行，話(huà)不多說(shuō)，有圖有真相

關(guān)鍵是，c#有現(xiàn)成的一個(gè)引用

右鍵點(diǎn)擊項(xiàng)目添加引用.Net找到System.Speech點(diǎn)擊確定
