python - 在pocketsphinx UI示例中单击“讲话”后，进程返回-11(0x-b)

我正在使用here中代码的精确副本。
每次我运行代码时，都会出现UI，并且事情似乎正在按照应有的方式运行。除非我单击“讲话”按钮，否则它将关闭并且终端将打印以下内容：

Process returned -11 (0x-b)

没有错误出现。它似乎就已经关闭了（我知道不是）。关于如何解决此问题的任何想法？

（编辑）这是我要执行的完整代码

最佳答案

我将其发布为获得正确格式的答案。不能保证这对您（或其他任何人）都有效！

我也将其升级为完整的Gtk3。

其他说明：

（1当我运行您的原始代码时，我遇到了Segmentation Fault。我怀疑您的操作系统返回的是信号-11而不是segfaulting。在Google上搜索Gst.State。PLAYINGSegmentation Fault会得到很多有趣的结果。

（2我没有使用GStreamer的经验，所以在这个问题上我不能为您提供很多帮助。我只是想将自己的结果和2美分贴出来。
