c# - System.ArgumentException: '找不到所需的 ID 识别功能。参数名称：文化'

Question

我得到了这个期望，但不知道如何解决它。

我尝试将文化更改为 fi-FI、en-EN、en-GB、en-US，它总是给人以这种期望。

我也尝试过不支持文化的解决方案和Go to Debug -> Options -> Debugging and tick "Enable Just My Code"这个。

.NET Framework 4.7.2 Visual Studio 2019 参考 System.Speech

using System;
using System.Speech.Recognition;

namespace SpeechRecognition3
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create an in-process speech recognizer for the en-US locale.  
            using (SpeechRecognitionEngine recognizer =
              new SpeechRecognitionEngine(
                new System.Globalization.CultureInfo("fi-FI")))
            {

                // Create and load a dictation grammar.  
                recognizer.LoadGrammar(new DictationGrammar());

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

                // Modify the initial silence time-out value.  
                recognizer.InitialSilenceTimeout = TimeSpan.FromSeconds(5);

                // Start synchronous speech recognition.  
                RecognitionResult result = recognizer.Recognize();

                if (result != null)
                {
                    Console.WriteLine("Recognized text = {0}", result.Text);
                }
                else
                {
                    Console.WriteLine("No recognition result available.");
                }
            }

            Console.WriteLine();
            Console.WriteLine("Press any key to continue...");
            Console.ReadKey();
        }
    }
}

我建议查看它的文档 https://docs.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo?view=netcore-3.1

“基于 RFC 4646 的文化名称格式为 languagecode2>-country/regioncode2，其中 languagecode2 是两个字母的语言代码，country/regioncode2 是两个字母的亚文化代码。”
