如何修复语法的语言与 vb 中语音识别器错误的语言不匹配

Question

你好，Visual Basic 我正在尝试创建一个语音识别系统，可以帮助我在计算机上的生活。我打电话给我的助手贾维斯。对于这个项目，我导入了 system.speech.dll。现在我收到这个错误：

创建表单时出错。有关详细信息，请参阅 Exception.InnerException。错误是：语法的语言与语音识别器的语言不匹配。

这是我的代码

Imports System.Speech.Recognition
Imports System.Speech.Recognition.SrgsGrammar
Imports System.Runtime.InteropServices 'For Monitor Command

Public Class Form1
    'This object represents the Speech recognition engine
    Private recognizer As SpeechRecognizer
    Dim QuestionEvent As String

    Public Sub New()

        InitializeComponent() ' This call is required by the Windows Form Designer.

        recognizer = New SpeechRecognizer() ' Add any initialization after the InitializeComponent() call.

        AddHandler recognizer.SpeechDetected, AddressOf recognizer_SpeechDetected 'this event is raised when the user begins to speak

        AddHandler recognizer.SpeechRecognitionRejected, AddressOf recognizer_SpeechRecognitionRejected 'this is raised when spoken words are not recognized as compliant to our grammar rules

        AddHandler recognizer.SpeechRecognized, AddressOf recognizer_SpeechRecognized 'this is raised when the application correctly recognizes spoken words


        'The rule is that each choice in the first Append method can be combined with each word specified
        'in the second method.
        Dim grammar As New GrammarBuilder()
        grammar.Append(New Choices(System.IO.File.ReadAllLines("Commands.txt")))

        'A grammar must be loaded into the engine. This is possible by loading an object or an xml file

由于这行代码recognizer.LoadGrammar(New Grammar(grammar))，我收到了该错误，但是我不确定如何修复该行

Here is an image of the error

任何帮助将不胜感激。谢谢。

Answer 1

我已经解决了。

您可以在声明识别器之前使用此代码修复此问题

先导入这个

Imports System.Threading
Imports System.Globalization

第二次添加这个

   Thread.CurrentThread.CurrentCulture = New CultureInfo("en-GB")

'或您当前的语言和国家'

   Thread.CurrentThread.CurrentUICulture = New CultureInfo("en-GB")

'或您当前的语言和国家'

Answer 2

就像我坐在不同的论坛上一样。我在朋友的电脑上遇到了同样的问题。所以我做了这个（它只是代码的一部分，因为所有的代码都很长）：

...
RecognizerInfo recognizerInfo = null;

foreach (RecognizerInfo ri in SpeechRecognitionEngine.InstalledRecognizers())
{
   if ((ri.Culture.TwoLetterISOLanguageName.Equals("en")) && (recognizerInfo == null))
   {
      recognizerInfo = ri;
      break;
   }

}

SpeechRecognitionEngine SpeachRecognition = new SpeechRecognitionEngine(recognizerInfo);

GrammarBuilder gb = new GrammarBuilder(startLiserninFraze);
gb.Culture = recognizerInfo.Culture;
grammar = new Grammar(gb);
SpeachRecognition.RequestRecognizerUpdate();
SpeachRecognition.LoadGrammar(grammar);
SpeachRecognition.SpeechRecognized += SpeachRecognition_SpeechRecognized;
SpeachRecognition.SetInputToDefaultAudioDevice();
SpeachRecognition.RecognizeAsync(RecognizeMode.Multiple);
...

所以这应该有效。我的朋友 PC 支持 2 个“en”或“eng”实例。不知道为什么。所以代码选择第一个。我在互联网上发现了一些代码和平，其中一些是由我制作的。

 SpeachRecognition.SpeechRecognized += SpeachRecognition_SpeechRecognized;

当一切都被识别时，就会发生事件。只需输入：

SpeachRecognition.SpeechRecognized +=

然后按 TAB 键几次。然后在代码的底部它会生成类似的东西：

void SpeachRecognition_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
   {
       //then will be some line that you need to replace with your code
   }

我希望这会有所帮助。 :)

您的选择更短。但是在输入它之后，我在运行 ower VS 2013 时收到了关于未安装 sintesyzer 或语言不可用的不同错误。删除代码发布版本后，我从 VS 运行了相同的错误，但从资源管理器中它没问题。有人知道这是为什么吗？

注意：通过SpeechRecognitionEngine类型的对象的构造，包括CultureInfo的参数以及Grammar对象的culture属性应该是一样的。 例如 - 我为两个对象使用“en-US”获得了相同的描述异常。 但是，当我在德语环境中对这两个对象都使用“en-GB”时，程序按预期工作！ 因此，首先检测允许的文化可能很有用。 在我看来，你可以避免对 >> Thread.CurrentThread.CurrentCulture SpeechRecognitionEngine 和 Grammar 对象的正确设置允许/安装的文化。
