GLOBAL TALK: A Multilingual Real-Time Text-to-Speech System

Abstract: GlobalTalk is a multilingual communication system designed to make interaction across languages smoother and more accessible. It brings together text-to-speech, translation, and pitch-controlled speech output in one unified platform. Built using Flask for backend routing and the Web Speech Synthesis API for real-time voice generation, the system allows users to log in, choose from available system voices, adjust pitch levels, and listen to text in clear, natural-sounding speech. Its translation feature, powered by Deep Translator, supports automatic language detection and enables easy conversion between multiple languages. The interface is simple and responsive, thanks to clean HTML/CSS layouts and modular JavaScript functions. User activity, such as spoken text and selected voices, is stored in memory to deliver a smooth and personalized experience. Overall, GlobalTalk offers an efficient and user-friendly environment for multilingual communication, while also providing a strong base for future enhancements like neural TTS, multi-agent extensions, and real-time conversational translation.
