我正在用Java做一个项目，要求我使用语音识别软件。基本上，我正在编写一个社交机器人＆＃34;，一个可以像个人一样与之互动的机器人。我正在使用＆＃34; Zeno R25＆＃34;。话虽如此，语音识别是编程机器人时的关键点。我正在使用Java编程机器人。
现在我尝试从https://github.com/cmusphinx/sphinx4下载Sphinx4演示程序，但这些程序无效。总共有四个，所有四个都无法工作，显然是处理Configuration对象的一些问题。例如，我从DialogDemo.java收到以下错误：
--- exec-maven-plugin:1.2.1:exec (default-cli) @ sphinx4-samples ---

当我试图运行它时。是的，我按照我应该的方式从DemoRunner类中启动了代码。 DialogDemo.java的代码如下，我标记了用箭头触发错误的流氓代码行：

与其他三个演示类似。任何帮助解决这个问题的人都将不胜感激。

您需要将sphinx4 jar包含在classpath中。如果您使用它，它可能是IDE中的设置，或者如果您使用命令行启动程序，则可以在命令行中添加它们。
