爪哇岛。LineUnavailableException、狮身人面像 API、Maven
Java. LineUnavailableException, Sphinx API, Maven
问：
当我运行应用程序时，它最初在 InitForm 上，一切正常。当我移动到另一个选项卡时，一切都很好，但是一旦我使用 InitForm 单击选项卡，一切都会挂起，然后在一段时间后挂起并抛出异常（下面的文本）。我一定搞砸了流或狮身人面像的侦听器创建，但我不知道如何解决它，我尝试了不同的组合，但没有任何帮助，我按主题发送代码： 异常文本：
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 16000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

我试图从代码中删除并行线程，但一切都没有呈现并挂起，因为整个程序现在正忙于语音识别。 接下来，我尝试删除同步，一切正常，但只抛出该异常，然后再次恢复工作，但始终识别出我不需要的内容。
当您单击按钮时，我需要它，如果识别已经开始（如果是第一次）或结束，相反，如果已经打开，则结束。我想过简单地使用等待通知技术来做到这一点，但出了点问题。
