.netvb播放提示音的简单介绍

想在vb.net的程序中有一个语音提示,该怎么写

首先添加一个系统的语音COM组件的引用microsoft speech object library然后在程序中声明一个语音类dim RC As SpeechLib.SpSharedRecoContext这个类有一些事件,如果你要处理它的一些事件,可以用withevent来声明然后在窗体LOAD事件或你需要的地方先创建一个实例RC = New SpeechLib.SpSharedRecoContext当一个RC被实例化后,系统就会运行语音识别程序.前提是你的系统已经正确安装这个功能.一般默认就已经安装好的.其次提醒一下,WIN7的语音识别比XP的好N倍.从阅读到侦听都好很多.然后就可以在你需要阅读的地方使用RC.Voice.Speak("hello 我", 11)11那里是一些枚举,用来标识系统用前台还是后台或其他方式来阅读文字,简单的来说就是阅读的时候不会卡住你的程序.你可以选其他的枚举来试试作用.以上为阅读部分.如果需要程序听你说话,则需要声明一个侦听类dim RG As SpeechLib.ISpeechRecoGrammar在初始化时将之与上面的RC建立关系,此时则必须要用withevent来声明上面的RC,因为涉及电脑听到你的语音后,会触发一个事件,并将听到的内容传递到该事件.其次,要让系统听到的解析为命令,就必须准备一个XML结构的文件来保存那些固定的命令.如果电脑在XML文件中找不到那些固定命令或同时不属于系统命令,电脑将会将其解释为听写.RG = RC.CreateGrammar '(0)

RG.CmdLoadFromFile("听到.xml", SpeechLib.SpeechLoadOption.SLODynamic)

RG.CmdSetRuleIdState(0, SpeechLib.SpeechRuleState.SGDSActive)然后写一个过程来处理听到的事件Private Sub 听到命令(ByVal StreamNumber As Integer, ByVal StreamPosition As Object, ByVal RecognitionType As SpeechLib.SpeechRecognitionType, ByVal 话语 As SpeechLib.ISpeechRecoResult) Handles RC.Recognition RC.Voice.Speak("我听到了" 话语.PhraseInfo.GetText, 11)End Sub以上为侦听部分.下面列一个XML的例文?xml version="1.0" encoding="gb2312"?

GRAMMAR LANGID="804"

RULE NAME="命令" TOPLEVEL="ACTIVE"

L

P打开播放器

P上我的QQ

P关闭你自己 /L

/RULE

/GRAMMAR要让系统正确地侦听到你说的话,前提你必须运行语音识别程序并让其激活到"正在聆听"状态.并且你必须有一个能正常使用的话筒而且保证话筒已经打开.(废话-_-|||)以上就是用VB.NET语音识别的最基本的一些操作.希望对你有帮助.更深入的内容有兴趣的话可以和我一起研究.

vb提示音问题

一、把你的提示音用转换器转化为wav格式,提示音文件不可太大,否则可能无法播放,控制在几Kb以内!

二、把wav格式的声音做成vb资源文件

三、用如下代码

Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (lpszSoundName As Any, ByVal uFlags As Long) As Long'API声明要放在程序代码最顶上

Private Sub Command2_Click()

Dim B() As Byte

B = LoadResData(101, "CUSTOM")

sndPlaySound B(0), H4 '播放内存里的声音,H8 ' 循环播放,H1 ' 异步播放

End Sub

vb.net 控件添加声音

建一个窗体,里面添加一个按钮,代码里拷入下面的代码,运行后,单击按钮

Private Declare Function sndPlaySound Lib "winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long

Private Const SND_ASYNC = H1 '异步播放

Private Const SND_SYNC = H0 '同步播放 (缺省)

Private Sub Command1_Click()

Dim SoundFile As String, Result As Long

SoundFile = "c:\Windows\Media\chord.wav"

Result = sndPlaySound(SoundFile, SND_ASYNC)

End Sub

说明:

要播放不同的声音,例如0-9,你找到相应的wav文件,编程实现就可以了。

PS:没注意到你是VB.NET,上面的代码是VB6的,生成工程文件,直接用.NET打开并自动转换,也可以使用。

VB.NET问题,做一个定时响铃提醒程序,怎样在程序中引用铃音,请写写代码,是在timer中添加代码吗

把类似下面的三行代码放入timer即可。关键是放音程序。

DealWav.mciSendString "open " sA " alias wav", sB, Len(sB), 0

DealWav.mciSendString "play wav ", sB, Len(sB), 0

DealWav.mciSendString "close wav ", sB, Len(sB), 0

VB.net如何加载音效?

方法一:调用系统DLL(这个有点不完善,也就是播放声音时窗体无法控制,效果相当于Enabled=true,但音频播放完毕后就没事了)

Private Declare Function sndPlaySound Lib "Winmm.dll" Alias "sndPlaySoundA" (ByVal lpszSoundName As String, ByVal uFlags As Long) As Long

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Dim SoundFile As String, Result As Long

SoundFile = "D:\KuGou\Pianoboy - 第105天.wav" '此处为路径

Result = sndPlaySound(SoundFile, 0)

End Sub

方法二:使用WindowsMediaPlayer(WindowsMediaPlayer1的可见为False)

先添加一个windowsmediaplayer控件(工具箱里没有,需要手动添加)

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

WindowsMediaPlayer1.visible=False

Me.WindowsMediaPlayer1.URL = "D:\KuGou\Pianoboy - 第105天.mp3"

End Sub

上面的都是点击button1(按钮1)后播放声音,若是鼠标移动到某控件上发出声音的话改一下触发事件就OK了。
