I'm using [the iSpeech library's
SpeechSynthesis class](http://www.ispeech.org/androidsdkdoc/com/ispeech/SpeechSynthesis.html). When I call the
speak method in a
for`循环,一次传递一个句子,所有句子立即开始。我猜这是因为该方法是非阻塞的。它不是开源的,所以我看不到它是如何工作的。我如何才能使它直到上一个句子完成后才开始一个句子? 最佳答案
通常,使用这些类型的库,代码不会等待声音停止播放(有充分的理由)。
从documentation of your library看来,您应该在阅读下一个句子之前用SpeechSynthesisEvent
收听PLAY_SUCCESSFUL
。
如果满足您的需求,javax.speech.synthesis
具有一种相当简单的机制可以等到演讲结束后,检查一下:http://java.sun.com/products/java-media/speech/forDevelopers/jsapi-guide/Synthesis.html
