CALL TRANSLATOR MOBILE APP – TELECOM Platform

Real-time multilingual communication via VOIP and PSTN

Cross-platform app for live call, message, and email translation

CALL TRANSLATOR is an advanced telecom and translation platform that enables real-time communication across different languages through mobile voice calls, messages, and emails. Combining the power of VOIP and PSTN technologies, it allows users to initiate App-to-App, App-to-Phone, and Phone-to-App calls with live translation in over 20 languages. The system integrates sophisticated translation pipelines using speech-to-text, text-to-text, and text-to-speech APIs to ensure smooth and clear communication across language barriers. The mobile app is designed for both Android and iOS users, offering a seamless multilingual experience with features such as translated in-app messaging, email communication with dual-language output (original + translated), and built-in browser translation. On the backend, the platform is powered by a robust cloud infrastructure that manages communication flow, translation requests, SIP routing, and user subscriptions. The admin panel provides tools for subscription plan management, monitoring call traffic, managing users, and overseeing server activity. This project delivers a unified communication solution ideal for global users, businesses, and customer support teams operating in diverse language regions. From user onboarding with secure authentication to cloud-hosted real-time translation of calls and content, CALL TRANSLATOR redefines the way multilingual communication is handled in the telecom space. It stands out as a complete communications-as-a-service (CaaS) platform, balancing complex telecom integration with an intuitive user experience.
