我正在尝试运行sphinx 4 pre aplha的对话框演示,但它会出错.

我正在创建一个实时语音应用程序.

我使用maven导入了项目,并遵循本指南的堆栈溢出:https://stackoverflow.com/a/25963020/2653162

该错误说明有关16 khz和通道为单声道的问题.很明显它是关于抽样的东西.关于麦克风也是如此.

我看了如何将麦克风设置更改为16 khz和16 bit,但在Windows 7中没有这样的选项

:

问题是,HelloWorld和对话框演示在sphinx4 1.06测试版中运行良好,但在我尝试了最新版本后,它会出现以下错误:

无法弄清楚如何解决这个问题.
