微软语音识别平台

我使用System.Speech在C#中编写了一个用于语音识别的应用程序,它可以在Windows 7上正常运行。 但是我在创建了适用于Windows 2003(x86)的相同应用程序之后。

我的编程环境: Windows 7 x64 Pro Visual Studio 2008

为了在我的编程环境中开发这个应用程序,我安装了:

1.Microsoft语音平台 - 服务器运行时(版本10.1)(x86)

2.Microsoft语音平台 - 软件开发工具包(SDK)(版本10.1)(x86)

3.Microsoft语音平台 - 服务器运行时语言(版本10.1)

(此处为en-GB安装了SR)

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

从SDK文档中粘贴此代码:

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。代码编译,但一旦我运行或调试它识别不起作用。知道我错过了什么吗?

您正在创建语音识别引擎而未指定引擎。由于您已安装了en-GB引擎,因此需要指定cultureinfo(或recognizerinfo):

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