Speech Accent Detector

Motivation

We wanted to create a project that could predict the country a person was raised in based on their speech accents. The idea behind this project is that most people develop distinctive linguistic patterns from the countries they grow up speaking in. Specifically, we want to identify noticeable accent patterns on English speech, and in the long term we hope that our project can be used to improve communication between people across various cultures and countries.
