class Grammar

This class contains the grammar of accepted sentences for a speech recognition experiment such as the one using SimpleDecoderSpeechHMM A grammar is a transition table where each node is a word.

Inheritance:

Public Fields

int n_words

the number of words in the grammar (different than the number of words in the lexicon, because the same word can appear twice in the grammar)

int* words

the index of the words (in the lexicon object)

int* start

this vector is used in SimpleDecoderSpeechHMM to keep the state index in the decoding state matrix, corresponding to the given word

bool** transitions

the transition matrix.

Documentation

This class contains the grammar of accepted sentences for a speech recognition experiment such as the one using SimpleDecoderSpeechHMM A grammar is a transition table where each node is a word. The user is responsible to set the transition table as he wishes. (by default, there are no transition!)

int n_words

the number of words in the grammar (different than the number of words in the lexicon, because the same word can appear twice in the grammar)

int* words

the index of the words (in the lexicon object)

int* start

this vector is used in SimpleDecoderSpeechHMM to keep the state index in the decoding state matrix, corresponding to the given word

bool** transitions

the transition matrix. each true transition (i,j) means the word whose index is i can be followed by the word whose index is j

Grammar(int n_words_)

This class has no child classes.
