java - Sphinx LineUnavailableException

Question

需要有关如何正确使用 Sphinx4 API 的帮助，我从这个链接阅读:http://cmusphinx.sourceforge.net/wiki/tutorialsphinx4,but当我运行 DialogDemo.java 时出现此错误:

Exception in thread "main" 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.

我在谷歌中搜索了如何修复它以及结果: Can't access microphone while running Dialog demo in sphinx4 5prealpha和 https://github.com/cmusphinx/sphinx4/issues/33但我不明白，有人可以向我解释如何正确地逐步使用 sphinx API 吗？

是的，示例 DialogDemo.java 存在问题。但其他样本工作正常。
