The Problem

Enabling scalable, real-time language practice

Fluency in any language requires consistent, real-world speaking practice. MySivi was built to meet this need by connecting users through live, topic-based audio conversations. However, scaling that experience to hundreds of thousands of users brought technical hurdles.

The team needed a real-time voice solution that could deliver ultra-low latency and reliable call quality under varying conditions. Stability, clarity, and performance were non-negotiable—especially when learners were trying to build confidence through fluid conversations.

MySivi chose Agora after evaluating its ability to support real-time, peer-to-peer voice communication at scale with minimal setup and engineering overhead.
