PIMIC’s Clarity NC100 AI Noise-Cancellation Chip Enables Robots to Understand Human Speech Accurately — Even in Busy Airports, Hospitals, and Public Areas
PIMIC Inc., a leader in ultra-efficient AI inference silicon powered by its Jetstreme™ processing-in-memory (PIM) architecture, announced a strategic partnership with Naiscorp Robotics, an emerging innovator in service and companion robots across banking, government, aviation, and homecare sectors.
Naiscorp Robotics has integrated PIMIC’s Clarity NC100 — a deep neural network powered, on-device noise cancellation chip — into its next-generation robotic platform. The NC100 delivers up to 40 dB of background and environmental noise reduction while consuming 150 uA, enabling robots to capture and understand voice commands with far higher clarity in complex, noisy real-world environments.
A Verified Performance Leap: ASR WER Improved From 15% to 5%
In recent field tests across malls, airports, and service halls, the Clarity NC100 improved Automatic Speech Recognition (ASR) Word Error Rate (WER) from 15% to 5% — a 66% reduction in misheard or missed commands.

This improvement translates into:
• More reliable command recognition
• Smoother and more natural conversations
• Higher user trust in customer-facing environments
• Meaningful performance boosts without cloud dependence
“We’re excited to work with Naiscorp Robotics to enable reliable robot interactions in noisy environments,” said Subi Krishnamurthy, CEO and CTO of PIMIC. “With up to 40 dB on-chip noise reduction, Clarity NC100 enables a new on-device standard.”
“Naiscorp builds robots that must operate where people actually live and work — inside banks, airports, clinics, and homes,” said Tai Nguyen, CEO of Naiscorp Robotics. “By integrating PIMIC’s NC100, we’ve achieved a breakthrough in voice reliability, reducing ASR errors from 15% to 5% at miniscule additional power consumption. That performance difference is immediately visible to customers.”
Real-World Traction Following NC100 Integration
With voice reliability dramatically improved, Naiscorp Robotics has already achieved:
• Commercial sales of service robots to multiple banks
• Demos and evaluation deployments with government agencies
• Showcase deployments with airlines and terminal service operators
• Development of a healthcare–homecare robot prototype for eldercare and chronic-care environments
These deployments validate the NC100’s value in real customer operations.
