Step 1 - Task Grammar

Create a new folder in your home directory and call it 'voxforge'.  Create another directory within this folder and call it 'howto'.

Create a file called sample.grammar in your 'voxforge/howto' folder, and add the following:

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

Still in your 'voxforge/howto' folder, create a file called sample.voca, and add the following:

% NS_B
<s>        sil

% NS_E
</s>        sil

% CALL_V
PHONE        f ow n
CALL        k ao l

% DIAL_V
DIAL        d ay ah 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 ah n
SIX        s ih k s
THREE        th r iy
TWO        t uw
ZERO        z iy r ow

For details on the file formats, see Step 1 - Task Grammar, in the Tutorial.

Compiling your Grammar

Download Julia mkdfa.jl grammar compiler script to your 'voxforge/bin' folder to compile your grammar files (sample.grammar and sample.voca) as follows:

(note you only need to execute the "cd" command if you are not already in the "auto" directory)

$ cd voxforge/auto      

$ julia ../bin/mkdfa.jl 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

This creates 3 files: sample.dfa, sample.term and sample.dict.
