Conversational Voice AI Agent Powered by DEN.Ai supports phone inquiries for businesses and local authorities.
DcodingX Corporation (Head Office: Chiyoda-ku, Tokyo; Representative Director: Ankit Kumar Chawla, hereinafter “DcodingX”) is pleased to announce that our “Conversational Voice AI Agent Powered by DEN.Ai”, which utilizes the interactive voice AI agent “DEN.Ai” developed and provided by our company, entered the market on 6 October 2026 via NEC NEXS Solutions Corporation (hereinafter “NEC NEXS Solutions”).
This announcement is issued by DcodingX, the provider of “DEN.Ai”, in response to the announcement made by NEC NEXS Solutions on 6 October 2026. Under this service, “DEN.Ai” is deployed within a cloud environment managed by NEC NEXS Solutions, combining DcodingX’s interactive voice AI technology with the implementation and operational expertise that NEC NEXS Solutions has cultivated in the domestic market. Through natural voice dialogue utilizing generative AI, the service handles initial telephone reception, ascertaining the nature of enquiries, providing guidance based on FAQs, transferring calls to the appropriate staff member, and transcribing, summarizing and recording call content. It thereby supports the streamlining of phone response operations and the improvement of service quality for companies, local authorities and other organizations.
Collaboration with NEC NEXS Solutions
In December 2025, DcodingX entered into an agreement with NEC NEXS Solutions regarding the resale of “DEN.Ai” and has since been rolling out the service across Japan. DcodingX is responsible for the service development, AI technology, functional improvements and service operations of “DEN.Ai”, while NEC NEXS Solutions contributes its expertise and customer base within the corporate and local government sectors. By combining these strengths, the two companies are promoting the implementation of AI phone services tailored to real-world operational challenges.
On 17 September 2026, as part of the collaboration between the two companies, a pilot program for citizens was launched in Asahi City Hall in Chiba Prefecture. This pilot program is evaluating ways to improve the convenience of various services and reduce the burden of staff handling phone inquiries by providing answers to frequently asked questions (FAQs) and directing or transferring calls to the appropriate department based on the nature of the inquiry.
About the conversational voice AI agent DEN.Ai
“DEN.Ai” is an interactive voice AI agent service developed and provided by DcodingX, utilizing generative AI. The AI responds to calls from users with a natural-sounding voice and answers inquiries based on pre-registered FAQs and various information. Furthermore, it enables the creation of response workflows tailored to each organization’s operations, including confirming the details of enquiries, transferring calls to the relevant department, and utilizing call records.
DcodingX holds a patent (Patent No. 7799365) for technology that generates responses to users’ voice inputs and is working to develop and improve services tailored to the telephone enquiry handling operations of Japanese companies and local authorities.
AI telephone responses using natural speech
Users can convey the details of their inquiry in a manner similar to a normal conversation, rather than simply selecting pre-defined menu options.
Responses utilizing organization-specific information
By utilizing FAQs, service information, facility guides and various regulations, organizations can build telephone guidance systems tailored to their specific needs and operations.
Call transfer based on the nature of the inquiry
The system assesses the nature of the user’s inquiry and transfers the call to the appropriate department or representative based on pre-set rules. This enables a hybrid operation combining fully automated AI responses with human intervention.
Various functions to support telephone support operations
We provide features that can be utilized for post-call review and analysis, such as call transcription, summarization, recording, management of call history, and visualization via a dashboard.
Future outlook
DcodingX will further strengthen its collaboration with NEC NEXS Solutions to promote the use of “DEN.Ai” across a wide range of industries and operations that handle a high volume of telephone inquiries, including customer support for local authorities and businesses.
Furthermore, by appropriately combining inquiries that can be handled by AI with tasks requiring human judgement and intervention, we aim to contribute to creating an environment where staff can focus on more specialized work and face-to-face interactions. We will continue to utilize insights gained from actual operations to improve our services and work to enhance the functionality and quality of “DEN.Ai” as an interactive voice AI service that supports telephone support operations as a whole.
