Does the language model works on the stt_hi_conformer_ctc_medium (Hindi Model)? And if yes, can you provide the steps required to create the. language model as well as the resource to use it with the pre-trained/fine-tuned model?
Kindly to use main branch, this feature is not for 1.15, and we have not released 1.16 yet
Yes as long as steps are followed from the docs ASR Language Modeling — NVIDIA NeMo , the HindI ASR model will process the text and build manifest, beam search will work. But may need to do hyper parameters search to get good beam scores.
for large scale grid search of hyper parameters you should still use the eval scripts mentioned in the documentation ASR Language Modeling — NVIDIA NeMo, Once you have good hyper parameters, this high level API is meant for use with final best beam alpha and beta to do beam search with model.transcribe()
Once we have 1.17 release, things will be smooth, We will add docs for high level API
