        private void button1_Click(object sender, EventArgs e)
        {
            speaker.Speak("A as in apple");

我在做一个程序，当你点击一个按钮，它会播放声音。我的问题是，我将有26个按钮，我必须设置其率和性别一个接一个。有没有办法让我长话短说。我试着去上课，但行不通。有人可以帮助我或知道这个教程在网上。我找了一些，但找不到我需要的。

我也试图改变我的声音性别为女性(正如你可以看到上面的代码)，但当我点击它在第一次它会播放一个男性的声音，但第二次点击后，它会播放女性。什么好主意吗?

提前感谢。

我不确定这是否是您想要的，但您可以将一个事件(如您的button1_Click)设置为每个按钮，然后使用sender属性来确定进一步的操作，如:

private static Dictionary<string, string> soundDictionary = 
    new Dictionary<string, string>();
private static void LoadDictionary()
{
    soundDictionary.Add("a", "A as in apple.");
    soundDictionary.Add("b", "B as in banana.");
}
private void PlaySound_Click(object sender, EventArgs e)
{
    var button = (Button)sender;
    var letter = button.Tag;
    speaker.Rate = -2;
    speaker.SelectVoiceByHints(VoiceGender.Female);
    speaker.Speak(dictionary[letter]);
}

确保在PlaySound_Click事件之前调用LoadDictionary()方法。

对于说话者的性别，你可以尝试在Speak()方法之前设置性别，如下所示:

speaker.Rate = -2;
speaker.SelectVoiceByHints(VoiceGender.Female);
speaker.Speak("A as in apple");

Answer 2

由于调用了speak方法，然后应用了女性性别配置，因此出现了性别语音问题。所以为了解决这个问题，你应该把配置然后调用speak方法，如下所示:

  speaker.Rate = -2;
  speaker.SelectVoiceByHints(VoiceGender.Female);
  speaker.Speak("A as in apple");

为了使代码更短首先你应该创建一个方法，接受Text和Gender它会执行speak，就像

下面

public void speak(String toSpeak, VoiceGender gender){
   SpeechSynthesizer speaker = new SpeechSynthesizer();
   speaker.Rate = -2;
   speaker.SelectVoiceByHints(gender);
   speaker.Speak(toSpeak );
}

您可以使用if语句来检查哪个按钮引发了maddin在他的回答中提到的事件，然后只需调用上面的函数

Answer 3

只需对每个按钮使用相同的函数，并创建一个

string buttonName = ((Button)sender).Name;
string speechText = string.Empty;
if (buttonName == "Button1"))
{ 
  speechText = "A as in apple";
} else if
...
speaker.Speak(speechText );
speaker.Rate = -2;
speaker.SelectVoiceByHints(VoiceGender.Female);

如果你使用Dictionary<string,string>甚至Dictionary<Control,string>，你甚至可以改进它

:

//in Form.Designer.cs
public partial class Form1 {
  private InitializeComponent() {
    //Code of the Designer
    this.button1.Text = "My Fancy Button";
    this.button1.Click += this.button_click;
    //Code of the Designer
    this.button2.Text = "My Other Fancy Button";
    this.button2.Click += this.button_click;
    //Code of the Designer
  }
}
//in Form.cs
public class Form1 : Form {
  //Constructor
  public Form1 () {
    InitializeComponent();
    this.SetupSpeechTexts();
  }
  private Dictonary<Control, string> speechTextDict = new Dictonary<Control, string>();
  private void SetupSpeechTexts() {
    this.speechTextDict.Add(this.button1, "First Text");
    this.speechTextDict.Add(this.button2, "Second Text");
    ...
  }
  private void button_click(object sender, EventArgs e) {
    Control senderControl = (Control)sender;
    if(this.speechTextDict.ContainsKey(senderControl)) {
      speaker.Speak(this.speechTextDict[senderControl]);
      speaker.Rate = -2;
      speaker.SelectVoiceByHints(VoiceGender.Female);
    }
  }
}
