Case Studies
EDENA works across voice, AI, dialogue, local communities, culture, space, and education — designing and implementing new kinds of experience at the seams between fields.
From experience design, prototyping, and proof-of-concept through to content development and operational planning, we walk alongside each project in the form it actually needs.
Voice / Voice in practice
Amazon Alexa Skill — cent.FORCE Premium Voice Series
Released July 11, 2023. (Trial service ended as of May 2026.)
We worked on this voice experience that delivered Alexa time and weather skills in the voices of cent.FORCE broadcasters.
A project that designed voice not as plain narration, but as a presence you bump into in the middle of an ordinary day.

AI / Dialogue experience prototyping
Voice Caster / RaShiSaAI proof of concept
Drawing on the voices and essences of broadcasters, characters, regions, and science missions, we prototype AI voice experiences that extend into dialogue, guidance, learning, and exploration.
Not an AI that simply answers questions — an experience whose presence you want to meet again.
