Multilingual-Translator

🌐 Multilingual Translator

Multilingual Translator a real-time multilingual translation app that allows users to type in one language and receive an instant translation in another, optionally with audio output. It supports 20+ languages and enables smooth, conversational interaction through a clean Streamlit interface. The backend is built with Flask and uses OpenAI's LLMs for high-quality translation and text-to-speech synthesis. The architecture follows an MCP server concept, where each task—text handling, translation, and speech generation—is treated as a modular tool. This design enables clean separation of logic, easier maintenance, and scalability for adding more tools (like summarization or Q&A) in the future.

🎯 Features

• 🔤 Text-to-Text Translation: Translate any input between major global languages using OpenAI.
• 🗣️ Text-to-Speech Generation: Speak out translations in a natural voice.
• 📲 Real-time Interface: Built with Streamlit for an interactive front-end experience.
• 🌍 Supports 20+ Languages: Easily switch source and target languages from dropdowns.
