Question

我有kylm生成的ARPA LM，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

以下是ARPA LM的摘录：

[n]
3

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

[closed]
true

[max_length]
1091

[vocab_cutoff]
0

[start_symbol]
<s>

[terminal_symbol]
</s>

[unknown_symbol]
<unk>

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

\end\

PS ：在\end\ 之后有一个新行

该例子表示SPHINX在最后一行遇到意外的EOF（不应该在那里遇到EOF吗？）

请任何帮助！

Answer 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，但您可以找到它here。

Sphinx 4损坏ARPA LM？
