Windows Phone 8语音合成器暂停

我正在开发一个应用程序,我想在语音合成器之间暂停。SpeakTextAsync正在运行,并从那里恢复。
await synthesizer.SpeakTextAsync(text);
当var stop = true;
停止读取
前段时间有人在这里发帖,同时我刷新了页面,读了他的回答,看到了一个通知& &;再次刷新页面&答案不见了。但不管是谁发帖,他都是救命恩人。它在我脑海里挥之不去,我最终创造了这个。
String text; // your text to read out loud
String[] parts = text.Split(' ');
int max = parts.Length;
int count = 0;
private String makeSSML() {
if (count == max) {
count= 0;
}
String s = "<speak version='"1.0'" ";
s += "xmlns='"http://www.w3.org/2001/10/synthesis'" xml:lang='"en-US'">";
for (int i = count; i < max; i++)
{
s += parts[i];
s += "<mark name='"anything'"/>";
}
s += "<mark name='"END'"/>";
s += "</speak>";
return s;
}
private void playIT(){
synth = new SpeechSynthesizer();
synth.BookmarkReached += synth_BookmarkReached;
synth.SpeakSsmlAsync(makeSSML());
}
private void synth_BookmarkReached(object sender, SpeechBookmarkReachedEventArgs e)
{
count++;
if (e.Bookmark == "END") {
synth.Dispose();
}
}
private void Pause_Click(object sender, RoutedEventArgs e)
{
synth.Dispose();
}
谢谢你,你的回答给了我灵感。
嗯,根据文档,当您调用CancellAll
时,您正在取消异步执行的任务。根据约定,这将导致抛出OperationCancelledException
。这意味着无论你在哪里调用SpeakTextAsync, SpeakSsmlAsync或SpeakSsmlFromUriAsync,你必须用try/catch语句包围这些调用,以防止此异常未被捕获。
例子:
private static SpeechSynthesizer synth;
public async static Task<SpeechSynthesizer> SpeechSynth(string dataToSpeak)
{
synth = new SpeechSynthesizer();
IEnumerable<VoiceInformation> englishVoices = from voice in InstalledVoices.All
where voice.Language == "en-US"
&& voice.Gender.Equals(VoiceGender.Female)
select voice;
if (englishVoices.Count() > 0)
{
synth.SetVoice(englishVoices.ElementAt(0));
}
await synth.SpeakTextAsync(dataToSpeak);
return synth;
}
public static void CancelSpeech()
{
synth.CancelAll();
}
现在在您想要的地方调用SpeechSynth("Some Data to Speak")
,并且每当您想要取消它时,只需调用CancelSpeech()
。
完成!享受……!
