Polylingo
Polylingo is a personal project covering the entire process from planning and prototyping to screen design.
Inspired by real user needs, it is a voice based simultaneous translation service designed for intuitive user experience and smooth interactions, with technical feasibility considered to explore real world applicability.

01. Problem recognization
02. research
UX research was conducted to define the service direction that best meets user needs.
The research began with analysing market trends in translation services and advancements in AI voice recognition to assess technical feasibility. This was followed by competitive analysis to identify key features and gaps, and user behaviour research to uncover pain points and opportunities within real usage contexts.

> Most translation services achieve real-time performance and accuracy,
but still lack in 1) Multi-speaker recognition 2) Maintaining long conversation flow, 3)General user-friendliness

> The way users translate varies depending on their goals and context.
In many cases, context, emotion, and conversational flow matter more than sheer translation accuracy.

03 Ideation
Before moving into wireframing, core features and essential technologies required for the app were defined. The interactions between users and the service were also visualised to clarify functional flows and the overall experience structure.
Core Functions & Tech Stack
Concept model
A concept model mapping how speech is recognised, translated, and synthesised before being delivered to users in a multi-speaker environment.
Network Diagram
A network diagram designed to show how a single feature can contextually expand into multiple goals and actions across different scenarios.
