[英]How to use System.Speech on non-English Win Vista Business
I´d like to try Speech recognition to controlling program. 我想尝试语音识别来控制程序。 I wrote test program in C# and when I´m debugging this, an error occurred every time -
我用C#编写了测试程序,调试时每次都会发生错误-
System.Runtime.InteropServices.COMException (0x80004005): Calling part of COM return error HRESULT E_FAIL.*
in System.Speech.Recognition.RecognizerBase.Initialize(SapiRecognizer recognizer, Boolean inproc)
in System.Speech.Recognition.SpeechRecognitionEngine.get_RecoBase()
in System.Speech.Recognition.SpeechRecognitionEngine.LoadGrammar(Grammar grammar)
It looks the error is caused by engine.LoadGrammar(new DictationGrammar());
看来错误是由
engine.LoadGrammar(new DictationGrammar());
引起的engine.LoadGrammar(new DictationGrammar());
On my notebook I installed CZECH OS Vista, and maybe this is the problem that speech recognition language is not the same as OS language. 在我的笔记本上,我安装了CZECH OS Vista,这也许是语音识别语言与OS语言不同的问题。
Is there a way how to developing with system.speech in non english OS, or am I wrong in some step? 有没有一种方法可以在非英语操作系统中使用system.speech进行开发,还是我在某些步骤上错了? There is no problem in language, I´d like use english for speech recognizing, but, I cannot get english Vista or MUI language pack.
语言没有问题,我想使用英语进行语音识别,但是我无法获得英语Vista或MUI语言包。
Full code is below. 完整代码如下。
Thanks a lot! 非常感谢!
using System;
using System.Windows;
using System.Speech.Recognition;
namespace rozpoznani_reci_WPF
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
SpeechRecognitionEngine engine = new SpeechRecognitionEngine();
try
{
engine.LoadGrammar(new DictationGrammar());
engine.SetInputToDefaultAudioDevice();
engine.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(recognizer_SpeechRecognized);
}
catch(Exception e)
{
//MessageBox.Show(e.ToString());
textBox1.Text = e.ToString();
}
}
void recognizer_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
if (e.Result != null)
{
textBox1.Text = e.Result.Text + " ";
}
}
}
}
According to the MSDN documentation on DictationGrammar
, the argument-free constructor 根据
DictationGrammar
的MSDN文档,无参数构造函数
Initializes a new instance of the DictationGrammar class for the default dictation grammar provided by Windows Desktop Speech Technology.
为Windows桌面语音技术提供的默认听写语法初始化DictationGrammar类的新实例。
Is there a Czech language DicationGrammar
class available on your machine? 您的机器上是否有捷克语
DicationGrammar
类? If not, you need to create one and use the other constructor DictationGrammar(String)
and load one from a URI. 如果不是,则需要创建一个并使用其他构造函数
DictationGrammar(String)
并从URI中加载一个。 You can also use GrammarBuilder
to construct your own and load it instead using SpeechRecognizer.LoadGrammar()
. 您也可以使用
GrammarBuilder
构造自己的文件并加载它,而不是使用SpeechRecognizer.LoadGrammar()
。
You might also find this link useful; 您可能还会发现此链接有用。 it's from 2008, but you did ask about Vista.
是从2008年开始的,但您确实询问过Vista。 :-)
