Question

以下是让PowerShell发言的方法。

Add-Type -AssemblyName System.Speech
$synthesizer = New-Object -TypeName System.Speech.Synthesis.SpeechSynthesizer
$synthesizer.Speak('Hey, I can speak!')

其实我想反对。如果我说话，可以将powershell转换成字母。

如果我在我的录音机中说“嘿，我可以说”，它会转换成文字吗？

如果可能请指导我如何实现它？

Answer 1

您可以使用System.Speech.Recognition。这里甚至是用PowerShell编写的示例用法：

用你的声音控制你的电脑......和PowerShell

Joel'Jaykul'Bennett于2009年6月25日

你有没有想过能够问你的计算机问题并让它大声回答你？你有没有想过你的计算机是否更像是运行星际迷航企业的计算机，响应语音查询和命令？您是否使用过ZWave或X10家庭自动化，并认为您的设备的语音控制将是明显的下一步？

好吧，好吧......我不会告诉你如何打开灯或使用家庭自动化 - 但这是让我思考这种语音识别的主要因素。什么极客不想走进起居室并说“电脑：灯亮”并让它发挥作用？

相反，作为所有这一切的第一步，让我向您展示如何使用PowerShell执行简单的语音命令识别脚本...这可以触发您需要编写的任何PowerShell脚本！下面的代码实际上是一个模块，虽然你可以将它作为脚本点源，并且它确实需要PowerShell 2.0用于事件，尽管使用Oisin的PSEventing库重构它以使用PowerShell 1.0是微不足道的。 / p>

这里基本上只需要担心一个功能：New-VoiceCommands。你传递一个哈希表，它将字符串映射到scriptblocks，如果你使用-Listenswitch就可以了。你也可以手动调用Start-Listening，当然，我已经提供了Say功能，让计算机更容易说话...

一旦计算机“聆听”......你只需说出它的名字，然后是你的一个命令。我喜欢这样，因为它确保我不会意外地运行脚本，但如果您认为没有必要，可以从GrammarBuilder的开头删除${Env:ComputerName},字符串，或者您可以将其硬编码到其他内容比你电脑的名字，比如说“哈尔，拜托，求求你......”或“电脑，请”或其他什么？

你可以做很多事情......真的......真的......但是为了给你一个你可以很容易理解的例子，我会做一些非常简单的事情，让我的电脑回答一下通过回复给我几个基本问题，然后添加一些命令让它启动应用程序或网页。

Add-SpeechCommands @{
   "What time is it?" = { Say "It is $(Get-Date -f "h:mm tt")" }
   "What day is it?"  = { Say $(Get-Date -f "dddd, MMMM dd") }
   "What's running?"  = {
      $proc = ps | sort ws -desc
      Say $("$($proc.Count) processes, including $($proc[0].name), which is using " +
            "$([int]($proc[0].ws/1mb)) megabytes of memory")
   }
} -Computer "Laptop" -Verbose 

Add-SpeechCommands @{
    "Run Notepad"= { & "C:\Programs\DevTools\Notepad++\notepad++.exe"}
}
Add-SpeechCommands @{
    "Check Gee Mail" = { Start-Process"https://mail.google.com" }
}

你觉得这有多容易吗？您可以使用“Say”来说出任何文本（尽管某些文本将获得比其他文本更好的结果），并且您可以调用任何其他powershell命令，包括用于获取Web数据的HttpRest命令，或用于Windows自动化的WASP命令，或者要显示的PowerBoots命令输出大文本或cmdlet来控制X10或ZWave设备......你知道吗？

Answer 2

语音识别仍是一项实验性技术。有一些.Net框架resources，即使有example。不过，不要指望很快创建一个PowerShiri。

Answer 3

这项技术有点过去“实验性”，但它远非可靠。

Exchange现在使用UM的“语音邮件预览”选项执行此操作。根据演讲者的不同，结果可能会有很好的变化，也可能很有趣。

Powershell可以说话，但如果我说话，它可以写吗？
