Detailed Description

Class Grammar uses as input a grammar file with extension '.fcfg' and has two functions:
get_rule_element: extracts the defined grammar rules

autocomplete()

def speech_recognition.kaldi_grammar.Grammar.autocomplete

(

self

)

# TODO: expand the full tree, not only the first words
# replace raw_input with the speech recognition output
# add an option to skip a word if it is not a match and to check the
# next word

Definition at line 82 of file kaldi_grammar.py.

check_word()

def speech_recognition.kaldi_grammar.Grammar.check_word	(		self,
			recognition = '',
			initial_list = []
	)

Checks if the recognised word is matching with the first element in the expanded sentences
As output it keeps a list of only the sentences, starting with the recognised word.

:param recognition: the recognised word
:param initial_list: bla
:return filtered_list: sentence list, filtered by its first word

get_words_()

def speech_recognition.kaldi_grammar.Grammar.get_words_

(

self

)

Extracts list with all the unique words, used within the grammar and

def speech_recognition.kaldi_grammar.Grammar.parse	(		self,
			sentence
	)

print_nicely()

def speech_recognition.kaldi_grammar.Grammar.print_nicely	(		self,
