c# - SpeechSynthesizer 到 Storyboard

Question

我创建了一个 Storyboard，其中包含一些移动元素/对象，我想将 SpeechSynthesizer 添加到 Storyboard中。

这可能吗？我正在使用 C#。

Storyboard myStoryboard=new Storyboard();

SpeechSynthesizer reader = new SpeechSynthesizer();  
reader.Speak("This is my first speech project"); /* instead of speak I want 
                                                    to add this into the storyboard
.....

myStoryboard.Children.Add(readerAnimation);

或者有没有办法将音频添加到 Storyboard中？

Answer 1

如果您愿意使用音频文件，可以使用 MediaTimeLine类(class)。然后您可以使用 SpeachSynthesizer's SetOutputToWaveFile 之一创建文件的方法。

保存从第二个链接修改的 waveFile:

using (SpeechSynthesizer synth = new SpeechSynthesizer())
{
    synth.SetOutputToWaveFile(@"C:\temp\Sample.wav");
    PromptBuilder builder = new PromptBuilder();
    builder.AppendText("Hello World !");
    synth.Speak(builder);
}

Xaml

修改自第一个播放文件的链接

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="100" Width="200">
    <StackPanel Background="Black">
        <Label Name="clickMe" Content="Click Me" Foreground="White" FontFamily="Arabic Typesetting" FontSize="20" HorizontalContentAlignment ="Center"   />
        <MediaElement Name="myMediaElement"  Width="0" Height="0" />
        <StackPanel.Triggers>
            <EventTrigger RoutedEvent="FrameworkElement.MouseDown" SourceName="clickMe">
                <EventTrigger.Actions>
                    <BeginStoryboard Name= "myBegin">
                        <Storyboard x:Name="myStoryBoard" SlipBehavior="Slip">
                            <MediaTimeline Source="C:\temp\Sample.wav" Storyboard.TargetName="myMediaElement" />
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger.Actions>
            </EventTrigger>
        </StackPanel.Triggers>
    </StackPanel>
</Window>

请注意，一旦 Storyboard 播放该文件，它将对其保持锁定状态。
