【问题描述】：

我有一个由kylm 生成的 ARPA LM，在运行 SPHINX 时，我得到了这个异常堆栈跟踪：

Exception in thread "main" java.lang.RuntimeException: Allocation of search manager resources failed
        at edu.cmu.sphinx.decoder.search.WordPruningBreadthFirstSearchManager.allocate(WordPruningBreadthFirstSearchManager.java:242)

        ... 3 more
Java Result: 1

这是 ARPA LM 的摘录：

[n]

[smoother]
kylm.model.ngram.smoother.KNSmoother

[closed]
true

[max_length]
1091

[terminal_symbol]

[unknown_symbol]

\data\
ngram 1=406
ngram 2=768
ngram 3=937
\1-grams: 
-99.0000    <s> -0.3630
...
...

\end\

PS：\end\之后有一个新行

异常表示 SPHINX 在最后一行遇到了意外的 EOF（它不应该在那里遇到 EOF 吗？？）

请帮忙！

【解决方案1】：

事实证明这是一个 SPHINX 4 错误。

如果\1-grams: 指令（或任何其他指令实际上）包含尾部空格[s]，SimpleNGramModel 无法解析它！我刚刚提交了补丁，你可以找到它here。
