Hi, I am expert python developer. I have wide experience in developing and consuming apis.
I will use requests for human module of python for sending requests to google api for storing .flac file. Once the request is complete , a callback will call google speech api for converting flac to text and there will be continuous polling for completion of using get request of long running google operation api. Once this operation is complete, I will call google api to fetch the text.
Thanks,
Amit
