Multilingual Text-to-Speech (TTS) Application

The project is a cutting-edge multilingual text-to-speech and translation application powered by AWS AI services. Users can convert text into natural-sounding speech and translate text across 11 languages, breaking language barriers effortlessly. Built with a serverless, scalable architecture, this application combines translation and TTS for a seamless multilingual experience.

Here’s what makes this project special:
