VB.net如何使用Microsoft Speech SDK5.1

安装了sdk后应该可以在控件箱单击鼠标右键，然后选择部件，在弹出的列表中应该可以找到microsoft tts engine或之类的东西，选择后就可以吧tts engine作为控件放到窗体上。 调用貌似是用.speak(String)实现的。 由于我是很久以前用的，所以也记得不是很清楚了，你可以找找看。

vb怎么调用系统tts朗读文本框里的内容？

先创建TTS对象，然后设置语言种类，设置音量，最后就是调用speak朗读文本框1中的内容，代码如下

Set objVoice = CreateObject("SAPI.SpVoice")

Set colVoice = objVoice.GetVoices()

objVoice.Volume = 100 

For i = 0 To colVoice.Count - 1 

If Right(colVoice(i).Id, Len("MSSimplifiedChineseVoice")) = "MSSimplifiedChineseVoice" Then cnVoice =i

Next

Set objVoice.Voice = colVoice.Item(cnVoice)  

objVoice.Speak (text1.text)

vb.net如何调用窗体之间的控件

Public Class ks

Inherits System.Windows.Forms.Form

#Region " Windows 窗体设计器生成的代码 "

Public Sub New()

MyBase.New()

'该调用是 Windows 窗体设计器所必需的。

InitializeComponent()

'在 InitializeComponent() 调用之后添加任何初始化

End Sub

'窗体重写 dispose 以清理组件列表。

Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)

If disposing Then

If Not (components Is Nothing) Then

components.Dispose()

End If

End If

MyBase.Dispose(disposing)

End Sub

'Windows 窗体设计器所必需的

Private components As System.ComponentModel.IContainer

'注意: 以下过程是 Windows 窗体设计器所必需的

'可以使用 Windows 窗体设计器修改此过程。

'不要使用代码编辑器修改它。
