SpeechRecognitionEngine.InstalledRecognizers返回未安装识别器

问题描述

我试图启动一个简单的语音识别程序，但是它不起作用，我已经安装了一些语言（en-GB和en-US），但是每当我使用以下语言时：

I am trying to get a simple speech recognition program started but it does not work, I've installed some languages (en-GB & en-US) but whenever I use the following:

它返回一个空集合。即使我只是尝试启动识别器，它也会返回 未安装识别器。但是当我重新安装一种语言时，它说它已经安装了。

it returns an empty collection. Even when I just try to start a recognizer it will return "no recognizer installed". But when I reinstall a language, it says that it is already installed.

using ( SpeechRecognitionEngine recognizer = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US")))
{
    // Create and load a dictation grammar.
    recognizer.LoadGrammar(new DictationGrammar());

    // Add a handler for the speech recognized event.
    recognizer.SpeechRecognized +=
      new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);

    // Configure input to the speech recognizer.
    recognizer.SetInputToDefaultAudioDevice();

    // Start asynchronous, continuous speech recognition.
    recognizer.RecognizeAsync(RecognizeMode.Multiple);

    // Keep the console window open.
    while (true)
    {
        Console.ReadLine();
    }
}

为什么找不到安装的识别器？

For what reason is it unable to find the installed recognizers?

编辑：

这是例外：{System.ArgumentException：找不到所需ID的识别器。
参数名称：System.Speech.Recognition.SpeechRecognitionEngine..ctor（CultureInfo文化）中的culture

This is the exception: {System.ArgumentException: No recognizer of the required ID found.Parameter name: culture at System.Speech.Recognition.SpeechRecognitionEngine..ctor(CultureInfo culture)

and： var识别器= SpeechRecognitionEngine.InstalledRecognizers（）; 返回一个计数为0的集合

and: var recognizers = SpeechRecognitionEngine.InstalledRecognizers(); returns a collection with a count of 0

推荐答案

The问题是我安装了 Microsoft.Speech 可以访问的语言包，而我在使用 System.Speech 我切换到 Microsoft.Speech 起作用了。

The problem was that I installed language packs that can be accessed by Microsoft.Speech and I was using System.Speech, when I switched to Microsoft.Speech it worked.
