Kobe City Tax Department Officially Adopts AI Shift's AI Worker VoiceAgent

AI Shift Inc. announced the official introduction of its AI Worker VoiceAgent at the Kobe City Tax Department to improve tax-related phone inquiry handling. This follows a successful trial from August 12 to October 31, 2025, conducted with NTT Marketing Act ProCX, which achieved a 65% automatic answer rate using voice scenarios and FAQ optimization. In the official rollout, the AI VoiceAgent will handle routine inquiries regarding resident taxes (such as tax notices, filings, and certificates) by interpreting intent and referencing FAQs. The system aims to automate over 70% of routine inquiries for specific tax items, reducing staff workload and improving service quality. If the agent cannot resolve an inquiry, the call is transferred to staff. AI Shift plans to enhance the voice agent's integration with generative AI to support more natural dialogue, expand the service to other tax items, and establish a primary reception system for all inquiries.
