Hey everybody,

i can't figure out how to setup a grammar that is based on the latest nightly builds of the acoustic models.  For testing i have configured a the following voca:

 % NS_B
<s> sil

% NS_E
</s> sil

% COMMAND_START_V
TIME            t ay m sp
DEPARTURE       d ix p aa r ch er sp

where i have configured two words that i selected from the dict file.
here's the grammar:

S : NS_B SENT NS_E
SENT: COMMAND_START_V

if i start julian i get some error msgs regarding missing phones:

###### check configurations
###### initialize input device
###### build up system
Reading in HMM definition...(ascii)...limit check passed
   defined HMMs:  6757
  logical names:  8564 in HMMList
    base phones:    44 used in logical
done
Making pseudo bi/mono-phone for IW-triphone...1062 added as logical...done
reading [grammar/nabaztag.dfa] and [grammar/nabaztag.dict]...
Reading in dictionary...
line 3: triphone "ay-m+sp" not found
line 3: triphone "m-sp+*" or biphone "m-sp" not found
> 2     [TIME]  t ay m sp
line 4: triphone "ch-er+sp" not found
line 4: triphone "er-sp+*" or biphone "er-sp" not found
> 2     [DEPARTURE]     d ix p aa r ch er sp
////// Missing phones:
ay-m+sp
ch-er+sp
er-sp+* or biphone er-sp
m-sp+* or biphone m-sp
//////////////////////
error in reading grammar/nabaztag.dict: 2 words failed out of 4 words

which seems to be correct as they are not listed in the tiedlist file.

can anybody give me a hint why these phones are missing? the master prompts files still lists some sentences using both "time" and "depature"

HI sebastien,

You don't use the "sp" (silence) phone for Julian grammar.

Therefore ... this: 

% COMMAND_START_V
TIME            t ay m sp
DEPARTURE       d ix p aa r ch er sp

should be this:

% COMMAND_START_V
TIME            t ay m

DEPARTURE       d ix p aa r ch er

For the nightly build, remember to take your pronunciations from the VoxForgeDic file. 

Hope that helps,

Ken

Hi Ken! 

Great! This solved the problem. The recognition works like a charm now!

Best regards,

Sebastian
