定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
将书签追加到 PromptBuilder。
public:
void AppendBookmark(System::String ^ bookmarkName);
public void AppendBookmark (string bookmarkName);
member this.AppendBookmark : string -> unit
Public Sub AppendBookmark (bookmarkName As String)
参数
- bookmarkName
- String
一个包含追加书签名称的字符串。
示例
以下示例创建一个包含两个书签的提示,并将输出发送到 WAV 文件进行播放。 当事件引发到控制台时, BookmarkReached 事件的处理程序会写入书签的名称及其在音频流中的位置。
using System;
using System.Speech.Synthesis;
namespace SampleSynthesis
{
class Program
{
static void Main(string[] args)
{
// Initialize a new instance of the SpeechSynthesizer.
using (SpeechSynthesizer synth = new SpeechSynthesizer())
{
// Configure the audio output.
synth.SetOutputToWaveFile(@"C:\test\weather.wav");
// Create a SoundPlayer instance to play the output audio file.
System.Media.SoundPlayer m_SoundPlayer =
new System.Media.SoundPlayer(@"C:\test\weather.wav");
// Build a prompt and append bookmarks.
PromptBuilder builder = new PromptBuilder(
new System.Globalization.CultureInfo("en-US"));
builder.AppendText(
"The weather forecast for today is partly cloudy with some sun breaks.");
builder.AppendBookmark("Daytime forecast");
builder.AppendText(
"Tonight's weather will be cloudy with a 30% chance of showers.");
builder.AppendBookmark("Nighttime forecast");
// Add a handler for the BookmarkReached event.
synth.BookmarkReached +=
new EventHandler<BookmarkReachedEventArgs>(synth_BookmarkReached);
// Speak the prompt and play back the output file.
synth.Speak(builder);
m_SoundPlayer.Play();
}
Console.WriteLine();
Console.WriteLine("Press any key to exit...");
Console.ReadKey();
}
// Write the name and position of the bookmark to the console.
static void synth_BookmarkReached(object sender, BookmarkReachedEventArgs e)
{
Console.WriteLine("Bookmark ({0}) reached at: {1} ",
e.Bookmark, e.AudioPosition);
}
}
}
注解
如果语音合成引擎在使用任何 Speak、BookmarkReachedSpeakAsync、 SpeakSsml或 SpeakSsmlAsync 方法发出提示时遇到书签,则会生成事件。
