Hello sir, my name is reshab and i am a python/django backend developer with over 3 years of experience in developing scripts, web apps, and api's.
For your requirement, i will use asyncio and aiohttp for asynchronous and multi threaded architecture of the script for maximising performance and also efficient at the same time. We will use google voice to text api as u have already mentioned and output the results in csv.
I am always open for any discussion, just leave me a message.
Thank You
Regards,
Reshab
