When testing the acoustic model I ran the instructions: 

julian -input rawfile -filelist wavlst -smpFreq 48000  -C julian.jconf  > juliusOutput  (copied from "step2-creating test prompts" )

but did not get the correct results.The error infomations  were:

--------------------------------

###### check configurations
###### initialize input device
###### build up system
Reading in HMM definition...(ascii)...limit check passed
   defined HMMs:    50
  logical names:   506 in HMMList
    base phones:    44 used in logical

line 18: triphone "z-ih+r" not found
line 18: triphone "ih-r+ow" not found
> 6     [ZERO]  z ih r ow
error in reading sample.dict: 1 words failed out of 18 words
ERROR: failed to read dictionary, terminated
Terminated

------------------------------ 

i compare my tiedlist with the one given in "Step 10 - Making Tied-State Triphones",and they are completely the same,and files sample.grammar and sample.dict are also copied from "step2-creating test prompts".

That is why?

Hi kay,

The pronunciation dictionary used in the Tutorial and How-to is based on the ISIP Switchboard corpus (contains around 27,500 words).  Whereas the  QuickStart and nightly AM builds is based on version 0.6 of the CMU Pronunciation Dictionary (contains around 130,000 words).   Unfortunately, the Switchboard and CMU pronunciation dictionaries use slightly different phoneme syntax.  This is enough to make them incompatible from a Grammar and Acoustic Model testing perspective (see ticket #52).

Did you select the correct sample.voca file in Step 2 - Create Test Prompts?  Your voca file pronunications need to match those  in the pronunication dictionary you used.   In this case, does the pronunciation dictionary you used to train your acoustic models use the same phonemes that you specified in your voca file?: 

[ZERO]  z ih r ow
