Microsoft语音识别平台

Question

我用System.Speech在C#中写了一个语音识别的应用，它在Windows7上运行良好。然而，我想要创建一个同样可以在Windows2003 (x86)上运行的应用。

我的编程环境: Windows 7 x64 Pro Visual Studio2008

为了在我的编程环境中开发这个应用程序，我安装了：

1.Microsoft Speech Platform -服务器运行时(版本10.1) (x86)

2.Microsoft Speech Platform -软件开发工具包(版本10.1) (x86)

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=4d36908b-3264-49ef-b154-f23bf7f44ef4

3.Microsoft Speech Platform - Server Runtime Languages (版本10.1)

(此处安装了适用于en-GB的SR )

在我的程序中，我使用了Microsoft.Speech.Recognition，而不是System.Speech；

粘贴SDK文档中的以下代码：

using Microsoft.Speech.Recognition;

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;

namespace WindowsFormsApplication1
{
  public partial class Form1 : Form
  {
    public Form1()
    {
      InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
      // Create a new SpeechRecognitionEngine instance.
      sre = new SpeechRecognitionEngine();

      // Create a simple grammar that recognizes “red”, “green”, or “blue”.
      Choices colors = new Choices();
      colors.Add("red");
      colors.Add("green");
      colors.Add("blue");

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

      // Create the actual Grammar instance, and then load it into the speech recognizer.
      Grammar g = new Grammar(gb);
      sre.LoadGrammar(g);

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

    // Simple handler for the SpeechRecognized event.
    void sre_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
      MessageBox.Show(e.Result.Text);
    }

    SpeechRecognitionEngine sre;
  }
}

我还在项目属性中将平台目标设置为x86。代码可以编译，但一旦我运行或调试它，识别就不起作用了。知道我错过了什么吗？

您正在创建一个未指定引擎的语音识别引擎。由于您已经安装了en-GB引擎，因此需要指定一个cultureinfo (或recognizerinfo)：

sre = new SpeechRecognitionEngine(new CultureInfo("en-GB"));
