JSGF parsing

[Yuval Karon]

Hello,

Could you please refer me to information about
the way pocketsphinx jsgf parser works?
and the related command-line arguments (apart from "-jsgf")

In particular:

• Does it support "import" ?

• Does it provide partial parses ?
  How does it handle unknown words? do I have to use <null> to support them?</null>

  For example:

  Suppose the rules are:

  <r1> = a b c d e
  <r2> = f g h
  

  and "w1", "w2" etc. do not appear in any rule

  Will the following inputs be recognized?
  and what will the hypothesis contain?

  • a b c
  • c d e
  • a c d
  • b c
  • a b g h
  • w1 a b
  • w1 a w2 b

Many thanks,
Yuval

Does it support "import" ?

Yes

How does it handle unknown words?

No, support for unknown words is not implemented yet

do I have to use <null> to support them?</null>

Null corresponds to empty transition and it is not relevant to unknown words.

a b c
c d e
a c d
b c
a b g h
w1 a b
w1 a w2 b

None of those will be recognized because grammar describes only two possible sequences.
