我正在尝试使用c#(windows窗体)制作语音识别应用程序。

以下是我正在使用的代码

//recognizing speech
SpeechRecognitionEngine r = new SpeechRecognitionEngine();
//then load the grammar
r.LoadGrammar(new Grammar(new GrammarBuilder
        (new Choices("hello","how are you","nice to meet you")))
        { Name = "speechGrammar" });

r.SetInputToDefaultAudioDevice(); // set the input of the speech recognizer to the default audio device
r.RecognizeAsync(RecognizeMode.Multiple); // recognize speech asynchronous

//adding a event handler
r.SpeechRecognized += r_SpeechRecognized;
//then create a method for that

void r_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
{
    if (e.Result.Text == "test") // e.Result.Text contains the recognized text
    {
        SpeechSynthesizer s = new SpeechSynthesizer();
        s.Speak("hello");
        MessageBox.Show("Hi User");
        s.Dispose();
    } 
} 

所以我希望程序将文本框的文本更改为所说的但不在语法中的单词/短语。

send a mail to xyz 句子不在语法列表中 所以当我说出来时我想要

textbox1.text = spokenword;

我应该对此结果的代码进行哪些更改。

你无法识别语法中没有的单词。你只需要做更大的语法。如果你想识别任意文本你可以使用DictationGrammar,它应该覆盖大部分单词。

识别文本后,您可以将其分配到文本框:

 textbox1.text = e.Result.Text;
