Realtime emotion detection : Correct API from client library

[ishwara-bhat]

Hi,
I need to integrate Angular-based audio and do real time emotion detection. I am creating my own chunks and will convert bytes to base64 at front end. Then I will send to python backend.
In this case, do I need real time client? When i looked at real time client, it sounded like it does some stream managemnet and b64 conversion. Since I'm doing this myself, is there any advantage of using real time?
If I keep sending audio data every 4 seconds, would it respond immediately? or with real time API, do you have any QoS consideration?
