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.
What’s better? Edutige ETM-006 vs Rode Videomic Pro
The Rode Videomic Pro is an extremely popular microphone that deserves the accolades it receives. The Videomic Pro is used by many vloggers and indy filmmakers. I happen to have one because I wanted to try it on a personal project. But my problem with it as a vlogging microphone is that it’s not exactly discreet. Whenever I’ve brought it anywhere, people usually mention that it looks like a big foam penis. Not cool.
So I decided to see how my favorite Edutige microphone, the ETM-006 vs the Videomic Pro. The ETM-006 is a lavalier microphone so it has the advantage of being closer to the subject than the Videomic Pro, but since most people use the Videomic on top of their camera, I think this is still a fair test of both microphones.
Have a listen with headphones and let me know what you think. I won’t be upset if you choose the Videomic Pro, but for me, I like the ETM-006. The Videomic Pro requires a battery, is much larger and doesn’t do well in echoey spaces, such as in the video. You need the right tool for the job, and for me, the ETM-006 works great for the types of videos I usually make. The other option, if you don’t need a lapel microphone is to try the ETM-001. The mics have the same performance but the ETM-001 doesn’t have a lavalier cable.
The mics were tested on my Canon EOS M, which has the same picture quality as other Canon DSLRs, and the same bad audio, as you’ll hear in the video.
