Build Real-Time Speech-to-Text with Translation
Blog post from Agora
A blog post outlines how to build a browser-based application that utilizes Agora’s Real-Time Communication (RTC) platform combined with its Speech-to-Text (STT) API to create live transcriptions and translations on video streams, aimed at developers interested in real-time multilingual communication solutions. The application architecture adopts a modular structure to improve maintainability, testability, and clarity by separating concerns across different modules such as transcription, RTC event handling, and user interface updates. It highlights the importance of proper state management, error handling, and user experience considerations, including features like dynamic translation control, auto-hiding overlays, and modular code for ease of updating. The post also addresses common issues like high latency and offers solutions for handling them while providing insights on advanced features such as request previews and S3 storage integration. It concludes with practical advice for extending the application and optimizing it for production, emphasizing the significance of real-time multilingual capabilities in global applications.
