Live Voice Translation for a Service Counter
Design a spoken translation flow that helps two people complete a practical conversation while keeping original speech and uncertainty accessible.
The brief
Understand the problem
Background
Short service conversations can fail when neither person shares a language. Live translation helps, but noisy rooms, names, technical terms, and uncertain transcription can change the meaning of a request.
User context
Mateo needs to explain a prescription pickup issue to a pharmacist who speaks another language. Both people can see the same counter tablet and need a respectful way to correct mistakes.
Product problem
The interface must establish who is speaking, make recording consent clear, and expose uncertain words without interrupting every exchange.
Objective
Create a turn-based spoken translation experience for a sensitive service conversation.
