Multilingual Text-to-Speech Converter

Description

The Multilingual Text-to-Speech Converter is a web-based application that allows users to input text and convert it into speech in various languages. This project integrates Google's Cloud Text-to-Speech API and Translation API to deliver high-quality speech synthesis in multiple languages. Users can enter text, choose their preferred language, and listen to the generated speech directly in their browser.

This application is built using Flask, a lightweight Python web framework, and leverages HTML5's audio capabilities for seamless playback of the synthesized speech. The project is designed to be user-friendly, enabling real-time speech synthesis without the need for file downloads.
