我正在玩这个SAPI v5.1库.所以我正在测试我的样本WAV文件.(从这里下载).无论如何,该文件中的声音清晰简单.它只包含一个单词,即第三个单词.现在,当我运行以下代码时,我得到数字8或"8".如果我删除它,我得到7.如果我尝试随机化列表我得到不同的结果,依此类推.我真的很困惑,开始认为SAPI库中的SpeachRecognition根本不起作用......

无论如何这里是我正在做的,

    private void button1_Click(object sender, EventArgs e)
    {
        //Add choices to grammar.
        Choices mychoices = new Choices();
        mychoices.Add("one");
        mychoices.Add("two");
        mychoices.Add("three");
        mychoices.Add("four");
        mychoices.Add("five");
        mychoices.Add("six");
        mychoices.Add("seven");
        mychoices.Add("eight");
        mychoices.Add("nine");
        mychoices.Add("zero");
        mychoices.Add("1");
        mychoices.Add("2");
        mychoices.Add("3");
        mychoices.Add("4");
        mychoices.Add("5");
        mychoices.Add("6");
        mychoices.Add("7");
        mychoices.Add("8");
        mychoices.Add("9");
        mychoices.Add("0");

        Grammar myGrammar = new Grammar(new GrammarBuilder(mychoices));

        //Create the engine.
        SpeechRecognitionEngine reco = new SpeechRecognitionEngine();

        //Read audio stream from wav file.
        reco.SetInputToWaveFile("3.wav");
        reco.LoadGrammar(myGrammar);

        //Get the recognized value.
        reco.SpeechRecognized += new EventHandler<SpeechRecognizedEventArgs>(reco_SpeechRecognized);

        reco.RecognizeAsync(RecognizeMode.Multiple);
    }

    void reco_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        MessageBox.Show(e.Result.Text); …

我试图用Windows 7识别语音,但它总是将语音识别为命令或只是说"那是什么？".

我怎么能得到所有的演讲？

码:

SpeechRecognizer _speechRecognizer;

    public Window1()
    {
        InitializeComponent();

        // set up the recognizer
        _speechRecognizer = new SpeechRecognizer();
        _speechRecognizer.Enabled = false;
        _speechRecognizer.SpeechRecognized +=
      new EventHandler<SpeechRecognizedEventArgs>(_speechRecognizer_SpeechRecognized); }
