Echo is a web application that aims to improve English pronunciation for passive English speakers by using AI to evaluate and give feedback on self-recorded audios and by providing words, sentences, and texts as practice material.

Many non-native English speakers struggle to find a place to practice speaking English. Echo provides a safe space to improve pronunciation by:

1. Providing words, sentences, and texts with American-accent voice recordings.
2. Allowing users to follow along and emulate the recordings.
3. Using AI to evaluate and give feedback on users' pronunciation.

1. Generate audio and transcriptions on any topic using AI, based on user requests.
2. Generate audio from user-provided text using AI.
3. Enable peer-to-peer evaluation through audio message exchange.
