SpeakWell - English-speaking Assessment System

SpeakWell is an innovative AI-powered mobile application designed to enhance users' English communication skills across various proficiency levels. From scratch, it leverages advanced technologies like FastAPI, Azure AI models, and machine learning to deliver real-time feedback and corrections. SpeakWell creates a personalised learning journey by providing actionable feedback and improving users' pronunciation, vocabulary, and sentence structure.

Problem Statement

Many individuals struggle to improve their spoken English due to limited access to personalised coaching and interactive practice tools.
