Question

我使用语音识别库得到以下代码：

var listen = new SpeechRecognitionEngine();
var reader = new Choices(File.ReadLines(@"C:\words.txt")
listen.LoadGrammar(new Grammar(new GrammarBuilder(reader)));
listen.SpeechRecognized += listen_SpeechRecognized;
listen.SpeechRecognitionRejected += listen_SpeechRecognitionRejected;
listen.SetInputToDefaultAudioDevice();
listen.RecognizeAsync(RecognizeMode.Multiple);

我有一个像这样的事件监听器......

static void listen_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
        {

            var talk = new SpeechSynthesizer();
            if (e.Result.Text == "Search Stock Symbol") 
            {
                talk.Speak("What symbol?");
                //Do I have to create another event listener?
                //a Listener .. symbol = a.Result.Text
                //talk.Speak(GetQuote(symbol))
            {
        }

我是否必须为＆＃34;会话＆＃34;？的每个部分创建一个事件监听器？如果是这种情况，还有更好的方法吗？

示例对话：

我：搜索股票代码
电脑：符号是什么？
我：AAPL
电脑：Apple正在交易....

不，只是那个，然后根据收到的文字改变你的行为。在之前的一些代码中：

    List<string> stockSymbols = new List<string>();
    stockSymbols.Add("AAPL");

然后

    string lastSpeechInput;

    static void listen_SpeechRecognized(object sender, SpeechRecognizedEventArgs e)
    {
        var talk = new SpeechSynthesizer();

        switch (e.Result.Text) {
            case "Search Stock Symbol":
                talk.Speak("What symbol?");
                break;
            default:
                break;
        }

        if (stockSymbols.Contains(e.Result.Text) && lastSpeechInput == "Search Stock Symbol") {
            talk.Speak(getStockPrice(e.Result.Text);
        }

        lastSpeechInput = e.Result.Text;
    }

与C＃语音库
