DEFiDE Inc., an AI/DX consulting company (Minato-ku, Tokyo, Representative Director: Tetsuya Yamamoto), announces the addition of a new Full Duplex AI Voicebot function, supporting two-way conversations, to its patented RAG-AI agent for corporations, "chai+" (Chai Plus).
In the call center and customer service industries, severe labor shortages and the increase in customer harassment (kashara) have become pressing social issues. This function was developed as an AI solution to directly address these two challenges.
■ Background of Development | Two Social Issues Facing Call Centers
【Issue ①】Chronic Labor Shortage ─ Call center turnover rate is second-worst among industries (20.3%) As the working population continues to decline, the call center industry faces chronic difficulties in recruitment and high turnover rates. For new operators alone, approximately half of companies see 1 in 5 leave within a year. Staff shortages lead to increased customer wait times and directly damage corporate brand image.
【Issue ②】Worsening Customer Harassment (Kashara) ─ In April 2025, a Kashara prevention ordinance will be enforced in Tokyo A survey by the Ministry of Health, Labour and Welfare (January 2024) revealed that kashara is the only type of harassment showing an increasing trend. Strong-worded complaints and prolonged verbal abuse over the phone further accelerate operator turnover, making legal and systemic responses an urgent necessity.
■ New Feature | What is a Full Duplex AI Voicebot?
The AI Voicebot added to chai+ is a next-generation voice AI function that supports "full duplex real-time conversation" similar to human interaction. Unlike traditional half-duplex (question-and-answer) systems, it can naturally interrupt while the other party is speaking and conduct continuous dialogues while understanding context.

Function |
Description |
|
Two-way Real-time Voice Conversation |
Understands context even when the customer is speaking, allowing for natural interruptions and responses. Achieves a human-like conversation experience. |
|
Integration with Internal Knowledge (RAG) |
Provides accurate voice responses by referencing patented learning technology information (FAQs, operational manuals, product information, service information) in real-time. |
|
24/7 Automatic Response |
Handles inquiries regardless of staffing, even at night, on holidays, or during busy periods. Achieves zero wait time. |
|
Automated Initial Reception for Customer Harassment |
Calmly receives and records emotional inquiries, escalating to human operators only when necessary. Protects operators. |
|
Integration with Existing Systems |
Supports integration with CRM, CTI systems, etc. Allows for smooth introduction into existing call center infrastructure. |
■ What Can Be Achieved Through Implementation
・ AI completely automates initial call center responses → Operators can focus on complex cases
・ Significantly reduces recruitment and labor costs through 24/7 unmanned operation
・ Reduces the mental burden on operators by having "AI handle initial reception for kashara calls → transfer to human only when necessary"
・ Zero customer wait time → Improves customer satisfaction (CS) and brand image
・ Automatic recording and analysis of call logs → Continuous service improvement using VOC (Voice of Customer)
■ Strengths of chai+ | Fusion of Patented Technology × AI Voicebot
chai+ has achieved over 96% accuracy in search and response (measured based on LLM judgment) by combining its unique search index and advanced data processing technology, and this technology is patented. In addition, it is possible to build an FAQ-type chatbot that provides 100% correct answers. This Full Duplex Voicebot function extends this patented technology to the voice domain.
By combining chai+'s existing RAG function (accurate responses from documents and FAQs) with voice interaction, it realizes true omnichannel customer support where it can "answer with the same accuracy whether by phone or chat."
■ Comment from Representative Director, Tetsuya Yamamoto
"The reality that call center operators continue to be exposed to unreasonable complaints and excessive demands is a social issue that Japan must confront. We designed AI not as a mere tool, but as a 'shield to protect people.' The Full Duplex Voicebot is not just an extension of automated responses. It's about AI receiving customer frustrations through human-like dialogue, with operators intervening only when truly necessary. We aim to realize such optimal collaboration between people and AI with chai+."
