Japan Trials AI Voice Companion to Help Elderly in Snowbound Towns

In the snowy city of Aizuwakamatsu, Japan, many older people find it hard to leave their homes during winter. To help them stay connected, NTT Docomo Business is trialing a voice-based AI assistant called CONN. It's like a friendly companion that can chat and share local information, all through a natural-sounding voice. The trial, done with Takeda Health Foundation and the city, began in autumn 2025 and has received positive feedback so far.

The key to CONN's appeal is its voice. NTT chose ElevenLabs' technology because it sounds remarkably human. "Japanese speech synthesis often sounds stilted," said Hironori Yoshida of NTT's Generative AI Taskforce. "With ElevenLabs, the intonation felt remarkably natural, and the emotional expression surprised me." This naturalness is crucial for building trust, especially for older users who may be wary of technology.

Beyond this trial, NTT sees many possibilities. They could integrate voice AI into their phone services or use it to support tourists with multilingual needs. Yoshida calls it "a new way of delivering trust." The AI isn't a real person, but it feels natural and trustworthy—something that wasn't possible before.

For everyday people, this means that AI could soon be a helpful companion for those who are isolated, providing not just information but also a sense of connection. It's a glimpse of how AI can be used to care for our aging population, making life a little easier and less lonely.
