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.
In this video youโll learn about why you might want to use separate audio for your videos. Youโll hear a comparison of the EIM-003 with an iPhone 6 vs the ETM-001 with a Canon EOS M. In some situations, itโs much better to use separate audio when making videos, instead of relying on a microphone connected to the camera.ย
For example, if the camera is far away from your subject and itโs a windy and/or noisy environment, youโll be better off using separate audio.
In addition, separate audio can increase the production value of your videos.
However, there is an extra step when editing to sync the audio. Editing software like Final Cut Pro X makes this an easy job, but itโs still an extra file and step. Youโll have to weigh the pros and cons and determine what is best for your particular situation.
For me, when I make videos for clients, itโs separate audio all the way. Itโs only if I know the video is not the main part of the project that Iโll use an external mic connected directly to the camera.
Hope that helps. Let me know if you have any questions about making videos or choosing a microphone.
