Python 进程在单击“后返回-11（0x-b）”；说；pocketsphinx用户界面示例中

我使用的是一份完全相同的代码副本。 每次我运行代码时，UI都会出现，并且似乎在做它们应该做的事情。除单击“Speak”（讲话）按钮外，它将关闭，终端将打印以下内容：

Process returned -11 (0x-b)

没有出现错误。它关闭的时候就好像它是注定的（我知道它不是）。你知道怎么解决这个问题吗

我将此作为一个答案发布，以获得正确的格式。无法保证这对您（或任何其他人）有效

我还将其升级为完整的Gtk3

其他说明：

（1）当我运行你的原始代码时，我发现一个分段错误。我怀疑你的操作系统返回的是信号-11而不是分段错误。在谷歌搜索Gst.State.PLAYING Segmentation Fault会得到很多有趣的结果

（2）我在GStreamer方面没有经验，所以在这个问题上我帮不了你很多。我只是想发布我的结果和我的2美分

（3部分代码来自

也请检查此项。ValueError:命名空间GES不可用于gi。require_version（'GES'，'1.0'）多亏了您的代码，我能够获得比单击“Speak”更进一步的信息按钮，但奇怪的是它没有录音。Pulseaudio没有显示任何设备录音，无论按钮的状态如何，也没有显示任何文本。对不起，我真的帮不了你更多。你可以发布一个新问题来解释你的问题，@Vindicium
