✨ Introduction
In this article, I’ll walk you through how I created Audio-To-Text Mail Assistant — a web application that helps deaf and hard-of-hearing learners convert any audio lecture into readable text that’s automatically emailed to them.
The app uses a Zapier automation to handle transcription (via Assembly AI) and email delivery, while the front end is built using Next.js and Tailwind CSS for a clean and accessible design.

🎯 Goal
The purpose of this application is to make audio-based learning content more accessible by allowing users to:
Record or upload an audio lecture.
Enter their email address.
Receive the transcribed text directly in their Gmail inbox.
