Real time emotion API integration from web #44

I intend to do audio capture from angular 8 client and then call real time API and render the emotion back to web. Please suggest the right architecture for this.

I understand that REST API can not be used. It needs the python client library. I can write python backend on cloud which could integrate client library. But with angular front end, if I use REST API, will it be fine interms of performance, any architectural issues? Please sugegst if any ideas on achieving this.
