[SRILM User List] unknown Word found in LM

[Thipe Modipa]

Hi,

I am decoding utterances with a dictionary containing about 800 unique
words with a language model containing about 63K unique words and I get the
following warning:

WARNING [-9999]  ReadARPAunigram: unknown Word 'h' found in LM -- ignored
 in HDecode

Will this warning have a negative impact on the word recognition accuracy,
or what is the general effect?

Thanks

Thipe
