ReSpeaker Audio Extractor Demo

This is a demo implementing a use case for Speech Emotion Recognition, using a Raspberry Pi 3 Model B+ and ReSpeaker Mic Array v2.0. The demo is a Python script that can be loaded in to continuously read audio incoming from the ReSpeaker and send API requests to SERaaS which then outputs emotions back.

SERaaS is a Final Year Project for Waterford Institute of Technology developed by Wei Kit Wong, which aims to provide a Speech Emotion Recognition as a Web API service. This is achieved by Machine Learning to build the SER classification model; the User Management Service to provide authentication features, and the API Service to deploy it all as a service.
