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

之后在控制台中我看到下一个:

错误:“ngram_search_fwdtree.c”,第 336 行:语言模型中的单词在字典中没有发音

日志中的这个错误应该暗示你出了点问题。

实际上,您使用了错误的选项,您应该使用-dict cmudict.dic,而不是-dic cmudict.dic
