您可以在日志中看到以下错误：
09-09 11:47:26.250: E/cmusphinx(7912): ERROR: "fsg_search.c", line 142: The word 'nine' is missing in the dictionary
09-09 11:46:59.750: E/cmusphinx(7912): ERROR: "kws_search.c", line 158: The word 'taking' is missing in the dictionary
您的词典似乎与更改不兼容。你需要确保字典里包含了所有必需的单词。
而且，我看到你做了一些改变，但大部分都是不完整的。例如，您在setupRecognizer中将代码注释为设置命名搜索，但没有更改切换代码，因此它仍然尝试切换到旧的搜索。你可以试试这样的东西，它应该会起作用：
