Korean Health Insurance Service Center Launches AI-based Voice Authentication

Innovative Voice Authentication AI Solution Implemented in Public Services

KT has successfully implemented an artificial intelligence (AI) based voice authentication service within the National Health Insurance Service Center’s customer support system. This groundbreaking technology ushers in a new era for public sector institutions by allowing users to verify their identity through their unique vocal properties.

Seamless and Secure Customer Verification Process

Unlike traditional methods that required sharing personal details verbally with a live agent, this AI solution encrypts and stores vocal information that distinctively identifies each customer. By simply speaking, customers can now be easily recognized by the system, expediting their access to services.

Advanced Protection Against Voice Spoofing

In anticipation of potential threats like ‘Deep Voice’ impersonations, KT has fortified the system with cutting-edge technology capable of detecting such fraudulent activities, thereby raising the bar for security standards.

Positive Impact on Customer Service Efficiency

The adoption of voice authentication has already shown significant results in improving operational efficiency at KT’s own call center—decreasing the average handling time for inquiries. This serves as a promising benchmark for the effectiveness of AI in enhancing both the speed and the safety of customer interactions.

Commitment to Continual Improvement of AI Authentication

Led by Choi Joon-gi, the executive in charge of KT’s AI business sector, the organization is determined to further refine and advance its voice authentication technology. This continual progress reflects KT’s dedication to evolving as an ‘AI innovation partner,’ consistently boosting the level of security and quality in customer service platforms nationwide.

Most Important Questions and Answers:

Q1: What is AI-based voice authentication?
A1: AI-based voice authentication is a technology that uses machine learning and voice recognition algorithms to verify a person’s identity by analyzing distinct characteristics of their voice. It provides a quick and secure way for individuals to access services without having to remember passwords or provide sensitive information every time they call customer support.

Q2: What challenges does AI-based voice authentication face?
A2: The key challenges include the potential for sophisticated voice spoofing technologies, the need for accented or dialectal voice inclusivity, dealing with voice changes due to illness or aging, and protecting voice data from theft or misuse.

Q3: What are the controversies associated with AI-based voice authentication?
A3: Controversies may arise over privacy concerns, with individuals worrying about how their biometric data (in this case, voice prints) is stored, used, and protected. There’s also potential for discrimination if the system does not perform equally well for all users regardless of accent, language, or vocal characteristics.


– Increases efficiency by reducing the time needed to authenticate identity.
– Enhances security by eliminating easily stolen passwords and reducing fraud.
– Provides a contactless and accessible option for individuals with physical disabilities.
– Can be updated continuously to counteract new spoofing methods.


– Requires individuals to enroll their voice print, which may be seen as invasive.
– Potential for false rejections if the voiceprint is not matched accurately due to various factors.
– Relies on robust infrastructure and adherence to privacy standards to protect sensitive voice data.
– Might have a learning curve for some users and require education on how to interact with the system.
