看起来你可以用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
作者:Joel 'Jaykul' Bennett 于 2009 年 6 月 25 日
你有没有想过能够问你的电脑问题并让它大声回答你?你有没有想过你的电脑是否可以更像运行星际迷航企业版的电脑,响应语音查询和命令?您是否玩过 ZWave 或 X10 家庭自动化,并认为您的设备的语音控制将是一个明显的下一步?
好吧,好吧……我不会向你展示如何打开灯或使用家庭自动化——但这是让我不断思考语音识别的主要内容。哪个极客不想走进客厅并说“计算机:灯亮”并让它工作?
相反,作为所有这些的第一步,让我向您展示如何使用 PowerShell 执行简单的语音命令识别脚本……它可以触发您想要编写的任何 PowerShell 脚本!下面的代码实际上是一个模块,尽管您可以将其作为脚本进行点源,并且它确实需要 PowerShell 2.0 来处理事件,尽管使用 Oisin 的 PSEventing 库重构它以在 PowerShell 1.0 上工作是微不足道的。

这里基本上只需要担心一个功能:New-VoiceCommands。您将一个哈希表传递给它,该哈希表将字符串映射到脚本块,如果您使用 -Listenswitch,这就是它的全部内容。你也可以手动调用Start-Listening,当然,我提供了Say功能,让电脑更容易说话……
一旦计算机“听”...您只需说出它的名称,然后是您的命令之一。我喜欢这样,因为它确保我不会意外运行脚本,但是${Env:ComputerName},
如果您认为没有必要,您可以从 GrammarBuilder 的开头删除字符串,或者您可以将其硬编码为计算机名称以外的其他名称,比如说“哈尔,拜托,我求求你……”或“电脑,拜托”之类的?
你可以用这个做很多事情......任何事情,真的......但是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,让我的电脑只回答几个基本问题回复我,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" }
}
你知道这有多容易吗?您可以使用“说”来说出任何文本(尽管某些文本会比其他文本获得更好的结果),并且您可以调用任何其他 powershell 命令,包括获取 Web 数据的 HttpRest 命令,或用于 Windows 自动化的 WASP 命令,或用于显示的 PowerBoots 命令以大文本输出,或用于控制 X10 或 ZWave 设备的 cmdlet……你知道吗?
