本文使用MSTTS实现了语音朗读功能,非常实用,你编写完就可以用它来帮助你朗读引文资料啦。只要进行下面的几个步骤就可以了。

1.安装MSTTS   如果你有装金山词霸,系统就已经安装了,可以在winnt/speech中打到vtxtauto.tlb文件;

2.用.Net SDK自带的tlbimp工具把vtxtauto.tlb转换成.dll格式: 

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

这时的mstts.dll已成为.net framework运行库的一个类。

3.编写一个封装vtxtauto的简单类:Speech .

//========================Speech.cs======================
using System;
using mstts; //MSTTS名称空间
namespace Bedlang{ //定义名称空间
       public class Speech{ 
                private VTxtAuto VTxtAutoEx; 
                public Speech( ){ 
                        VTxtAutoEx = new VTxtAuto(); 
                        VTxtAutoEx.Register(" "," "); //注册COM组件 
                } 
                public void Speak(String text){ 
                        VTxtAutoEx.Speak(text, 0); //发音 
                } 
        }
}
//========================Speech.cs======================

4.编译Bedlang.Speech 

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

如果用vs.net开发,可直接生成项目就可以了。

5.发音实现 

分别加入Label,TextBox,Button控件各一个到windows Form中,修改它们的属性,源代码如下:

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

using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
using System.Data;
namespace Bedlang

        /// 
        /// Form1 的摘要说明。 
        /// 
        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; 
                /// 
                /// 必需的设计器变量。 
                /// 
                private System.ComponentModel.Container components = null; 
                public demo() 
                { 
                        // 
                        // Windows 窗体设计器支持所必需的 
                        // 
                        InitializeComponent(); 
                        // 
                        // TODO: 在 InitializeComponent 调用后添加任何构造函数代码 
                        // 
                } 
                /// 
                /// 清理所有正在使用的资源。 
                /// 
                protected override void Dispose( bool disposing ) 
                { 
                        if( disposing ) 
                        { 
                                if (components != null) 
                                { 
                                        components.Dispose(); 
                                } 
                       } 
                        base.Dispose( disposing ); 
                } 
                #region Windows Form Designer generated code 
                /// 
                /// 设计器支持所需的方法 - 不要使用代码编辑器修改 
                /// 此方法的内容。 
                /// 
                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 = "输入要朗读的文字:"; 
                        // 
                        // 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 = "朗读"; 
                        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 
                /// 
                /// 应用程序的主入口点。 
                /// 
                [STAThread] 
                static void Main() 
                { 
                        Application.Run(new demo()); 
                } 
                private void button1_Click(object sender, System.EventArgs e) 
                { 
                        Speech s=new Speech(); //创建一个Speech对象 
                        if(textBox1.Text.Length==0) 
                                s.Speak("Please input letter."); //发音 
                        else 
                                s.Speak(textBox1.Text); 
                } 
        }
}
//========================demo.cs======================

6.编译demo.cs 

csc demo.cs /r:bedlang.dll

也可以在在Visual Studio.net集成开发环境中直接编译。

7.运行demo.exe

输入要要朗读的文字,看看是否能正确读出来。
