Anyway to extract Transcript from Hindi audio files ? (Hindi audio files to Hindi transcripts)

Futureized

Skilled
I found couple of tools but all are paid, can we extract transcript from audio files in HINDI ?
(didnt liked the accuracy, as basic grammar was completely messed, making a complete different meaning)

Need to extract in source language only = Hindi
 
A friend works at this startup: https://symbl.ai/platform/understanding-apis/transcription/

They are advertising 1000 mins of free transcription, and hindi is supported. I don't know if they have a tool, though: you may have to write some python.
Thanks a lot, they provide solutions to websites/app developers with there data model.
Signed up for same and its too extensive, cannot locate any pre-made tool to test my audio files.
Thanks for sharing (its worth a bookmark, will come handy in future)
