c# - 'SAPI 没有实现拼音选择' 异常

Question

每当我尝试在我的笔记本电脑上编写任何语音识别程序时，我总是会收到如下所述的相同消息。我总是可以编译我的代码并让 Windows 窗体应用程序运行。但问题是，该程序将检测不到我的声音..程序无法运行..

我非常确定我的代码工作正常，因为我通常从 youtube 视频中获取代码，例如:https://www.youtube.com/watch?v=KR0-UYUGYgA还有很多..我正在为我的项目使用 .NET Framework 4 客户端配置文件。我仅引用“system.speech”...我的问题可能是什么？

我收到的调试消息:

speaker.vshost.exe Information: 0 : SAPI does not implement phonetic alphabet selection.
A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in System.Speech.dll
A first chance exception of type 'System.InvalidOperationException' occurred in System.Speech.dll
A first chance exception of type 'System.InvalidOperationException' occurred in System.Speech.dll
A first chance exception of type 'System.InvalidOperationException' occurred in System.Speech.dll

我试过的示例代码:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Speech.Synthesis;
using System.Speech.Recognition;
using System.Threading;
using System.Threading.Tasks;

namespace speaker
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        SpeechSynthesizer sSynth = new SpeechSynthesizer();
        PromptBuilder pBuilder = new PromptBuilder();
        SpeechRecognitionEngine sRecognize = new SpeechRecognitionEngine();

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            pBuilder.ClearContent();
            pBuilder.AppendText(textBox1.Text);
            sSynth.Speak(pBuilder);
        }

        private void button2_Click(object sender, EventArgs e)
        {
            button2.Enabled = false;
            button2.Enabled = true;
            Choices sList = new Choices();
            sList.Add(new string[]{"hello","test","it works","how","are","you","today"});
            Grammar gr = new Grammar(new GrammarBuilder(sList));

            try
            {
                sRecognize.RequestRecognizerUpdate();
                sRecognize.LoadGrammar(gr);
                sRecognize.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sRecognize_SpeechRecognized);
                sRecognize.SetInputToDefaultAudioDevice();
                sRecognize.RecognizeAsync(RecognizeMode.Multiple);
            }
            catch
            {
                return;
            }
        }

        void sRecognize_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            //if (e.Result.Confidence >= 0.3)
            MessageBox.Show("speech is:" + e.Result.Text.ToString());
        }


    }
}

你需要

 gram.Culture = New System.Globalization.CultureInfo("en-GB")
