80040154类未注册（HRESULT的例外：0x80040154（REGDB_E_CLASSNOTREG））

Question

Microsoft. S中出现类型为System. Runtime. InteropServices. COMExctive的未处理异常peech.dll

其他信息：检索CLSID为{49428A60-C997-4D0E-9808-9E326C178D58}的组件的COM类工厂失败，原因是以下错误：80040154类未注册（HRESULT异常：0x80040154（REGDB_E_CLASSNOTREG））。

我以下是Microsoft语音平台SDK 11的MSDN示例：

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

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void button1_Click(object sender, EventArgs e)
        {
            SpeechRecognitionEngine sre = new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"));                        ======>>**ERROR** 
            sre.SetInputToWaveFile(@"c:\Test\Colors.wav");
            Choices colors = new Choices();
            colors.Add(new string[] { "red", "green", "blue" });

            GrammarBuilder gb = new GrammarBuilder();
            gb.Append(colors);

            Grammar g = new Grammar(gb);
            sre.LoadGrammar(g);

            // Register a handler for the SpeechRecognized event.
            sre.SpeechRecognized +=
              new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);

            // Start recognition.
            sre.Recognize();

            sre.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(sre_SpeechRecognized);
        
        }

        private void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {
            MessageBox.Show("Speech recognized: " + e.Result.Text);
        }

       
    }
}

Answer 1

在我的例子中，它也帮助安装了微软语音平台运行时。尽管我已经安装了语音软件开发工具包和Kinect软件开发工具包。

Answer 2

听起来您只安装了64位版本的Speech Platform运行时，而不是32位版本。
