EDUTIGE Announces Deployment of ETM-009 Series Microphones in Korea Expressway Corporation's Multi-Vehicle Smart Kiosks 

SEOUL, South Korea — EDUTIGE Corp. (Founder: Mr. Henry Kim), a leading Korean manufacturer of professional microphone solutions, today announced the launch of its new ETM-009 Series microphone lineup. Purpose-built for smart AI kiosk applications, the new series is designed to deliver highly accurate voice capture in demanding public environments where background noise and acoustic reflections can significantly affect speech recognition performance.

Overcoming Noise Challenges in Public Kiosks

As AI-powered kiosks become increasingly common in public facilities such as highway service areas, transportation hubs, and government service centers, reliable voice recognition has become a critical requirement. However, conventional microphones often experience reduced speech recognition accuracy due to ambient noise, reverberation, and continuous public activity.

To address these challenges, EDUTIGE developed the ETM-009 Series using its proprietary acoustic design and voice-focused engineering, enabling clear and reliable speech capture even in acoustically challenging environments.

ETM-009 Series: Purpose-Built for Voice AI

The ETM-009 Series consists of three specialized unidirectional (cardioid) microphone models, each optimized for different kiosk designs and installation requirements. All models are engineered to maximize speech intelligibility while reducing unwanted environmental noise, making them well suited for Voice User Interface (VUI) applications.

The lineup includes:

ETM-009
The standard unidirectional model optimized for close-range speech capture and reliable voice recognition in noisy public environments.

ETM-009M
A compact version designed for installations where internal space is limited, providing flexible integration into slim kiosk enclosures without compromising audio performance.

ETM-009S
A premium, high-directivity model developed for barrier-free kiosk applications, maximizing voice isolation while minimizing surrounding environmental noise for the highest possible speech recognition accuracy.

Supporting Barrier-Free Digital Services

The ETM-009 Series was developed with accessibility in mind, helping support voice-driven kiosk systems that are easier to use for older adults, people with visual impairments, and other users who may find touchscreen-based interfaces challenging.

By providing highly accurate speech input, the microphones contribute to a more intuitive and inclusive user experience, allowing AI systems to recognize spoken commands more reliably in real-world public environments.

"Our goal is to reduce the communication gap between users and automated systems through dependable voice capture," said Henry Kim, Founder and CEO of EDUTIGE. "The ETM-009 Series is designed to help AI kiosks recognize speech accurately on the first attempt, creating a more accessible and user-friendly experience for everyone."

Looking Ahead

Building on its expertise in professional microphone technology, EDUTIGE plans to expand the ETM-009 Series into a wide range of smart public infrastructure projects and AI-enabled self-service systems.

As demand for intelligent voice interfaces continues to grow, the company aims to strengthen its presence in the global smart-city, transportation, and automated service markets while establishing new standards for high-performance directional microphone solutions.
