How to build a software which can recognise your speech?

Question

How can I build a software which recognises all the Indian languages and would change it’s own language as the language of user changes and is compatible with all sort of accents? I don't want to use any already availabe API because some are costly and some do not support our accent.

Can I use c++ for this task.

Answer 1

Cpp Idk
But python it's very easy to implement😊
Disclaimer: I AM NOT PYTHON FAN.😆

Answer 2

... if you dont want to use a api u gonna need to have like a few 100 TB is data...

Answer 3

What if I want to make changes in the existing package like speech_ recognition in python?
Actually speech_recognition package is not responding correctly to Indian accent, which halts the implementation.

So is there any way in which I can make it compatible with the desired accent?
