__init__(FsgModel self, char const * name, LogMath logmath, float lw, int n) -> FsgModel __init__(FsgModel self, char const * path, LogMath logmath, float lw) -> FsgModel

Overrides: object.__init__

word_id(FsgModel self, char const * word) -> int

Look up a word in the FSG vocabulary.

Word ID for this word

word_add(FsgModel self, char const * word) -> int

Add a word to the FSG vocabulary.

Word ID for this new word.

trans_add(FsgModel self, int src, int dst, int logp, int wid)

Add the given transition to the FSG transition matrix.

Duplicates (i.e., two transitions between the same states, with the same word label) are flagged and only the highest prob retained.

null_trans_add(FsgModel self, int src, int dst, int logp) -> int

Add a null transition between the given states.

There can be at most one null transition between the given states; duplicates are flagged and only the best prob retained. Transition probs must be <= 1 (i.e., logprob <= 0).

1 if a new transition was added, 0 if the prob of an existing transition was upgraded; -1 if nothing was changed.

tag_trans_add(FsgModel self, int src, int dst, int logp, int wid) -> int

Add a "tag" transition between the given states.

A "tag" transition is a null transition with a non-null word ID, which corresponds to a semantic tag or other symbol to be output when this transition is taken.

As above, there can be at most one null or tag transition between the given states; duplicates are flagged and only the best prob retained. Transition probs must be <= 1 (i.e., logprob <= 0).

1 if a new transition was added, 0 if the prob of an existing transition was upgraded; -1 if nothing was changed.

add_silence(FsgModel self, char const * silword, int state, float silprob) -> int

Add silence word transitions to each state in given FSG.

Parameters:
-----------

state:  state to add a self-loop to, or -1 for all states.

silprob:  probability of silence transition. 

add_alt(FsgModel self, char const * baseword, char const * altword) -> int

Add alternate pronunciation transitions for a word in given FSG.

writefile(FsgModel self, char const * path)

Write FSG to a file.
