ngram_order in language model #1594

Closed YangangCao closed 1 week ago

YangangCao commented 2 weeks ago

Hi, Dear author,

I want to improve the accuracy grammar ASR, so I set ngram_order to 3 in language model , but appear this: ASSERTION_FAILED (VoskAPI:AssignFstStates():language_model.cc:137) Assertion failed: (current_fst_state == num_active_lm_states_) Any idea to set more than 2 ngram_order? Thanks very much!

Please clarify in more details what exact changes have you made. Is it to grammar code?

I only change opts.ngram_order from 2 to 3 in LanguageModelOptions in recognize.cc
