Live Testing with Julian

1. Update your julian.jconfjulian.jconf file (and make sure you Julian grammar files are in the adapt directory).

2. Create 'sample' grammar files similar to the ones from your How-to or Tutorial - they should look something like this:

Note: these sample grammar files use different pronunciations than your How-to and Tutorial pronunciations.  The VoxForge Speaker Independent Acoutic Model uses the larger CMU dictionnary, whereas the How-to and Tutorial uses the smaller Switchboard dictionnary, which has slightly different pronunciations than CMU's dictionnary.

sample.grammar:

S : NS_B SENT NS_E
SENT: CALL_V NAME_N
SENT: DIAL_V DIGIT

sample.voca:

% NS_B
<s>        sil

% NS_E
</s>        sil

% CALL_V
PHONE        f ow n
CALL        k ao l

% DIAL_V
DIAL        d ay ax l

% NAME_N
STEVE        s t iy v
YOUNG        y ah ng

% DIGIT
FIVE        f ay v
FOUR       f ao r
NINE        n ay n
EIGHT        ey t
OH        ow
ONE        w ah n
SEVEN        s eh v ih n
SIX        s ih k s
THREE        th r iy
TWO        t uw
ZERO(2)    z ih r ow

3. Compile your grammar files (sample.grammar and sample.voca) with the mkdfa.pl script as follows (note: using the HTK 3.3 version of this script is OK):

$mkdfa.pl sample
sample.grammar has 3 rules
sample.voca    has 6 categories and 18 words
---
Now parsing grammar file
Now modifying grammar to minimize states[-1]
Now parsing vocabulary file
Now making nondeterministic finite automaton[6/6]
Now making deterministic finite automaton[6/6]
Now making triplet list[6/6]
---
generated: sample.dfa sample.term sample.dict
 

Make sure your Microphone volume is similar to when you created your audio files. Then run Julius with:

$julius-4.3.1 -input mic -C sample.jconf
