第C#windows語音識別與朗讀實例C#windows語音識別與朗讀示例，供大家參考，具體內容如下

本示例通過windows語音識別功能進行語音識別和文本朗讀。

打開windows麥克風，點擊start按鍵，大聲朗讀“中國”、“美國”、“英國”，識別成功將發(fā)出“嘟”的提示音并朗讀對應結果。

用到的語音識別模塊包括：

usingSystem.Speech.Recognition;

usingSystem.Speech.Synthesis;

動態(tài)連接庫文件在我的資源中下載.System.Speach.dll

示例界面如下：

程序源碼如下：

usingSystem;

usingSystem.Runtime.InteropServices;

usingSystem.Speech.Recognition;

usingSystem.Speech.Synthesis;

usingSystem.Threading;

usingSystem.Windows.Forms;
