我尝试在Windows下测试CMUSphinx库的工作。 我查看http://cmusphinx.sourceforge.net/wiki/tutorialpocketsphinx中的教程 并构建sphinxbase和pokectsphinx库。
然后我尝试检查已构建的库是否正常工作，并使用下一个选项启动pocketsphinx_continuous.exe应用程序：
C:\Users\admin>D:\Work\Elis\Win32\pocketsphinx-0.8-win32\bin\Release\pocketsphinx_continuous.exe -hmm d:\Work\Elis\Win32\pocketsphinx-0.8-win32\model\hm
m\en_US\hub4wsj_sc_8k -dic d:\Work\Elis\Win32\pocketsphinx-0.8-win32\model\lm\en
_US\cmu07a.dic -lm d:\Work\Elis\Win32\pocketsphinx-0.8-win32\model\lm\en_US\wsj0
vp.5000.DMP
之后在控制台中我会看到下一个：

答案 0 :(得分：1)
错误：“ngram_search_fwdtree.c”，第336行：语言模型中没有单词有p 字典中的发音
日志中的这个错误应该暗示你出了问题。
实际上，您使用了错误的选项，应该使用-dict cmudict.dic，而不是-dic cmudict.dic
