本文使用MSTTS實現(xiàn)了語音朗讀功能，非常實用，你編寫完就可以用它來幫助你朗讀引文資料啦。只要進行下面的幾個步驟就可以了。

1.安裝MSTTS   如果你有裝金山詞霸，系統(tǒng)就已經(jīng)安裝了,可以在winnt/speech中打到vtxtauto.tlb文件；

2.用.Net SDK自帶的tlbimp工具把vtxtauto.tlb轉(zhuǎn)換成.dll格式: 

tlbimp vtxtauto.tlb /silent /namespace:mstts /out:mstts.dll

這時的mstts.dll已成為.net framework運行庫的一個類。

3.編寫一個封裝vtxtauto的簡單類:Speech .

//========================Speech.cs======================
using System;
using mstts; //MSTTS名稱空間
namespace Bedlang{ //定義名稱空間
       public class Speech{ 
                private VTxtAuto VTxtAutoEx; 
                public Speech( ){ 
                        VTxtAutoEx = new VTxtAuto(); 
                        VTxtAutoEx.Register(" "," "); //注冊COM組件 
                } 
                public void Speak(String text){ 
                        VTxtAutoEx.Speak(text, 0)； //發(fā)音 
                } 
        }
}
//========================Speech.cs======================

4.編譯Bedlang.Speech 

csc /target:library /out:Bedlang.dll speech.cs /r:mstts.dll

如果用vs.net開發(fā)，可直接生成項目就可以了。

5.發(fā)音實現(xiàn) 

分別加入Label,TextBox,Button控件各一個到windows Form中，修改它們的屬性，源代碼如下：

//========================demo.cs======================

using System；
using System.Drawing；
using System.Collections；
using System.ComponentModel；
using System.Windows.Forms；
using System.Data；
namespace Bedlang
{ 
        /// 
        /// Form1 的摘要說明。 
        /// 
        public class demo : System.Windows.Forms.Form 
        { 
                private System.Windows.Forms.Label label1； 
                private System.Windows.Forms.TextBox textBox1； 
                private System.Windows.Forms.Button button1； 
                /// 
                /// 必需的設(shè)計器變量。 
                /// 
                private System.ComponentModel.Container components = null； 
                public demo（） 
                { 
                        // 
                        // Windows 窗體設(shè)計器支持所必需的 
                        // 
                        InitializeComponent（）； 
                        // 
                        // TODO: 在 InitializeComponent 調(diào)用后添加任何構(gòu)造函數(shù)代碼 
                        // 
                } 
                /// 
                /// 清理所有正在使用的資源。 
                /// 
                protected override void Dispose（ bool disposing ） 
                { 
                        if（ disposing ） 
                        { 
                                if （components != null） 
                                { 
                                        components.Dispose（）； 
                                } 
                       } 
                        base.Dispose（ disposing ）； 
                } 
                #region Windows Form Designer generated code 
                /// 
                /// 設(shè)計器支持所需的方法 - 不要使用代碼編輯器修改 
                /// 此方法的內(nèi)容。 
                /// 
                private void InitializeComponent（） 
                { 
                        this.label1 = new System.Windows.Forms.Label（）； 
                        this.textBox1 = new System.Windows.Forms.TextBox（）； 
                        this.button1 = new System.Windows.Forms.Button（）； 
                        this.SuspendLayout（）； 
                        // 
                        // label1 
                        // 
                        this.label1.Location = new System.Drawing.Point（24, 16）； 
                        this.label1.Name = "label1"； 
                        this.label1.Size = new System.Drawing.Size（120, 23）； 
                        this.label1.TabIndex = 0； 
                        this.label1.Text = "輸入要朗讀的文字："； 
                        // 
                        // textBox1 
                        // 
                        this.textBox1.Location = new System.Drawing.Point（24, 48）； 
                        this.textBox1.Name = "textBox1"； 
                        this.textBox1.Size = new System.Drawing.Size（248, 21）； 
                        this.textBox1.TabIndex = 1； 
                        this.textBox1.Text = ""； 
                        // 
                        // button1 
                        // 
                        this.button1.Location = new System.Drawing.Point（112, 112）； 
                        this.button1.Name = "button1"； 
                        this.button1.TabIndex = 2； 
                        this.button1.Text = "朗讀"； 
                        this.button1.Click += new System.EventHandler（this.button1_Click）； 
                        // 
                        // demo 
                        // 
                        this.AutoScaleBaseSize = new System.Drawing.Size（6, 14）； 
                        this.ClientSize = new System.Drawing.Size（292, 197）； 
                        this.Controls.AddRange（new System.Windows.Forms.Control[] { 
                        this.button1, 
                        this.textBox1, 
                        this.label1}）； 
                        this.Name = "demo"； 
                        this.Text = "demo"； 
                        this.ResumeLayout（false）； 
                } 
                #endregion 
                /// 
                /// 應(yīng)用程序的主入口點。 
                /// 
                [STAThread] 
                static void Main（） 
                { 
                        Application.Run（new demo（））； 
                } 
                private void button1_Click（object sender, System.EventArgs e） 
                { 
                        Speech s=new Speech（）； //創(chuàng)建一個Speech對象 
                        if（textBox1.Text.Length==0） 
                                s.Speak（"Please input letter."）；　//發(fā)音 
                        else 
                                s.Speak（textBox1.Text）； 
                } 
        }
}
//========================demo.cs======================

6.編譯demo.cs 

csc demo.cs /r:bedlang.dll

也可以在在Visual Studio.net集成開發(fā)環(huán)境中直接編譯。

7.運行demo.exe

輸入要要朗讀的文字，看看是否能正確讀出來。
