Company Overview

ProLingo provides expert simultaneous interpretation and translation services, helping businesses and events bridge language gaps. With over 20 years of experience and advanced equipment, they ensure clear communication across diverse audiences, making them a reliable partner for multilingual conferences and meetings nationwide.

Key Challenges

Prolingo required an integrated, scalable solution that addressed these challenges while also improving the overall quality and reliability of its services.

Interpretation ManagementProLingo required a sophisticated system capable of facilitating simultaneous interpretation across multiple languages. This system needed to ensure that both in-person and remote audiences could listen to sessions in real-time, in their chosen language, and without any delays.

Remote Interpreter IntegrationMany interpreters worked remotely, requiring secure and reliable access to the event network through VPNs, which needed to be seamlessly managed without performance issues.

Network ConstraintsEnsuring the system worked efficiently in intranet-based environments, as many events lack stable internet connectivity.

Offline Event OperationMany event venues lacked reliable internet connectivity, making it essential for the system to function over local intranet environments without relying on internet connectivity.

User ExperienceEnsuring that attendees could easily access the interpretation services, with an intuitive, seamless experience, regardless of device or location.

Real-Time Interpretation Enabling live interpretation for various languages, while maintaining minimal latency.

Multi-Platform Support A suite of apps was developed for simultaneous interpretation: native iOS/Android apps for the audience, an Android tablet app for interpreters, PWAs for audience access, and a web interface for technicians and admins.

User AccessibilityOffering seamless user experiences for a wide range of audience members, joining events from different geographical locations and/or devices.

Performance and ScalabilityThe system had to work across a variety of devices, including tablets, smartphones, and laptops, and support large attendees spread across different geographical locations and simultaneous sessions while supporting interpreters and attendees in real-time while also maintaining optimal interpretation performance.
