NTT-AT to launch RelAi 窓口アシスタント on October 15

The service is built on findings from a counter-AI pilot conducted at Katsushika Ward. According to NTT-AT, feedback from municipal staff and issues in counter operations were reflected in the product, with improvements to the user interface and operating methods as well as added functions for real-world use. That makes the Katsushika work the evident origin of the commercial offering, though the body does not detail what specifically changed.

A notable feature set separates this from a generic chat tool. Voice recognition runs in real time and summarizes conversations, speaker separation uses NTT-AT's own high-directivity compact microphone "FR-1200", and personal information such as names and addresses is automatically masked in the transcript. Answers are generated from ward knowledge such as manuals, FAQs and ordinances, with the supporting document shown and the relevant passage highlighted, and the system also records and summarizes interactions and creates response records.

The commercial version adds functions aimed at two kinds of gaps the pilot may have surfaced. Translation addresses multilingual needs for communication with foreign residents, and a customer-harassment alert lets staff press a button on a smartphone to notify managers of possible harassment, who can then check the conversation record to understand the situation and the visitor's demands. Together with deployment in a dedicated environment not used for AI training and support for closed networks such as LGWAN, the package appears aimed at the security requirements municipal buyers typically impose.
