java - Google Glass 未列出的上下文语音命令无法正常工作

Question

我无法识别未列出的语音命令。我无法像我期望的那样使用语音命令 "ok glass" -> "Test" 启动应用程序。但是我可以使用“ok glass”在我的应用程序中调用菜单。菜单可以正确显示所有 3 个菜单项，但是说 "rotate"、"free rotate"、"stop rotate" 不会影响任何事情。我认为未列出的命令的识别有问题，但我不明白。有什么建议么？我也想知道从菜单项到语音触发器的连接是如何发生的，因为菜单项只知道String.xml的字符串？使用触摸条控制菜单效果很好。

Answer 1

我尝试了一些语音命令，这是我的发现:

1. “测试”似乎不起作用。另一方面，首字母小写的“test”确实有效。这似乎只影响某些词，因为我已经能够成功地使用“下一步”作为触发器。
2. 将字符串资源“Stop Rotate”更改为“stop_rotate”有效。
