我使用C#编写了一个使用System.Speech进行语音识别的应用程序,该应用程序在Windows 7上运行良好。
但是,我正在创建将在Windows 2003(x86)上运行的相同应用程序。
我的编程环境:
Windows 7 x64专业版
Visual Studio 2008年
为了在我的编程环境中开发此应用程序,我安装了:
1.Microsoft Speech Platform-服务器运行时(版本10.1)(x86)
http://www.microsoft.com/downloads/details.aspx?FamilyID=674356C4-E742-4855-B3CC-FC4D5522C449&displaylang=en&displaylang=en
2.Microsoft语音平台-软件开发工具包(SDK)(版本10.1)(x86)
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=4d36908b-3264-49ef-b154-f23bf7f44ef4
3.Microsoft语音平台-服务器运行时语言(版本10.1)
(此处已安装en-GB的SR)
http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=f704cd64-1dbf-47a7-ba49-27c5843a12d5
在我的程序而不是System.Speech中,我使用了Microsoft.Speech.Recognition;。
从SDK文档中粘贴了以下代码:
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,但是一旦我运行或调试它,识别就无法正常工作。知道我想念什么吗?
最佳答案
您正在创建语音识别引擎而未指定引擎。由于已经安装了en-GB引擎,因此需要指定cultureinfo(或recognizerinfo):
sre = new SpeechRecognitionEngine(new CultureInfo("en-GB"));
