NTT Docomo Business trials voice AI for older residents facing winter isolation

ElevenLabs reports positive early feedback from a voice-AI trial serving residents in Aizuwakamatsu, Fukushima, including older people who struggle to leave home during heavy winter snow. Its October 16, 2026, customer account describes NTT Docomo Business’s community service and the speech technology behind it. The field trials began in autumn 2025.

A community service for snowbound days

Heavy snow creates a practical barrier for older residents: getting out of the house can become difficult in winter. The trial pairs two resident-facing functions—providing local information and offering everyday conversation—rather than limiting the assistant to answering a narrow set of transactional questions.

NTT Docomo Business is conducting the trial with Takeda Health Foundation and the cooperation of Aizuwakamatsu City. The company is the enterprise-solutions arm of one of Japan’s largest telecommunications providers; here, its deployment is a voice-based community platform.

The assistant is called CONN. It is NTT Docomo Business’s product, powered by ElevenLabs’ ElevenAgents technology.

The choice turned on how Japanese sounded

“With ElevenLabs, the intonation felt remarkably natural, and the emotional expression surprised me,” Yoshida said. He connected that impression to trust, describing the synthetic voice as “A new way of delivering trust.”

The early reception is encouraging, according to ElevenLabs, but remains a qualitative assessment from the technology supplier. Its customer account does not quantify improvements in residents’ lives. Yoshida’s description explains the appeal of the voice, not a measured finding about the assistant’s reliability.
