问题：语音合成后显示WPF窗口。 [英] Problem: WPF window displays after the speech is synthesized.

问题描述

这是我的MainWindow.xaml.cs：

this is my MainWindow.xaml.cs:

using statements...
....;
namespace xyz
{
 class abc :Window
 {
  public SpeechSynthesizer qwe;
  public abc()
  {
   InitializeComponent();
   qwe = new SpeechSynthesizer();
   qwe.Speak("Hello");
  }
 }
}

问题是语音是在窗口被显示之前合成的。

i希望窗口加载其所有内容，然后说出文字。

推荐答案

在窗口的<之前不要调用 Speak 方法code>已加载事件触发：

Don't call the Speak method until the window's Loaded event fires:

public abc()
{
    InitializeComponent();
    qwe = new SpeechSynthesizer();
    Loaded += Window_Loaded;
}

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    qwe.Speak("Hello");
}

如果还是太快，请使用 Dispatcher ：

If that's still too soon, use the Dispatcher:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    Dispatcher.BeginInvoke((Action)() => qwe.Speak("Hello")), DispatcherPriority.ContextIdle, null);
}

或者，使用 SpeechSynthesizer.SpeakAsync方法 [ ^ ]：

Alternatively, use the SpeechSynthesizer.SpeakAsync method[^]:

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    qwe.SpeekAsync("Hello");
}
