Denwa Hoso Kyoku Co., Ltd. (Headquarters: Kita-ku, Osaka; President: Masayuki Mori; hereinafter "Denwa Hoso Kyoku"), a subsidiary of GROWTH VERSE Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director and Chairman & CTO: Mitsunori Minamino; Representative Director and President & CEO: Tomohiro Watabe; hereinafter "GROWTH VERSE") and a provider of DX solutions for telephone support such as IVR (voicebots), will launch the "DHK CANVAS Agent Plan" on April 15, 2026. This plan is positioned as an advanced and flagship model of their no-code voicebot "DHK CANVAS," equipped with autonomous generative AI.
Leveraging Denwa Hoso Kyoku's extensive IVR experience, which has supported telephone response automation for many years, and GROWTH VERSE's advanced technical capabilities in building AI Agents, they have successfully released a solution that traditionally takes several years to develop, in a short period of just three months.
New Value Provided by "DHK CANVAS Agent Plan"
Our proprietary technology resolves the conflicting challenges faced by conventional voicebot providers in telephone response automation—namely, the inability to answer questions outside predefined scenarios—and the difficulty of control inherent in generative AI.
1. Balancing Scenario-Type "Controllability" with Agent-Type "Flexibility"
It is possible to combine and balance scenario control with autonomous processing by an AI agent, depending on the call reason and inquiry content.
Precise Procedures
Processes where errors are unacceptable, such as identity verification and address changes, are securely guarded by scenarios.
Flexible Conversations
For FAQs and complex inquiries, the AI agent autonomously makes judgments and guides the conversation to a resolution through natural, human-like dialogue.
2. Instantly Learns In-house Knowledge, Enables Automated Phone Responses
By directly learning call center FAQs, Voice of Customer (VoC) feedback, and manual information, we build highly accurate AI agents. This enables "thinking phone support" 24 hours a day, 365 days a year, replacing human operators.
Reasons Why Denwa Hoso Kyoku Co., Ltd. Is Chosen
In conjunction with this release, we have redefined Denwa Hoso Kyoku's strengths. Our greatest feature is our ability to provide cutting-edge AI "securely and affordably" thanks to our robust infrastructure.
[Reason 1] Overwhelmingly "Safe and Secure" Infrastructure Supporting Over 7,000 Lines
We directly connect lines to our self-operated data centers and have established a redundant configuration with multiple carriers. This is controlled by our proprietary logic, which supports large-scale operations with over 7,000 lines. As we do not rely on external platforms, we ensure high stability and security.
[Reason 2] High Cost Performance Through "Per-Case Billing (Per-Call Billing)" That Sets Us Apart from Other Companies
Unlike many voicebot providers who adopt "per-minute billing" based on call duration, we offer "per-case billing (per-call billing)." Because we maintain our own infrastructure and can directly control line costs, we can dramatically improve cost efficiency even for AI conversations that tend to be lengthy.
