KT Debuts Voice Authentication AI Service at National Health Insurance Service Center

Enhanced Customer Service Through Innovative Voice Recognition
KT has unveiled a significant advancement in customer service for the National Health Insurance Service’s call center, marking the first time a public institution in South Korea has adopted an AI-powered voice authentication system. The solution streamlines customer verification process during calls by utilizing unique voice characteristics.

Developed in collaboration with the health insurance body from last October, the AI Contact Center (AICC) project harnesses Speech-To-Text (STT) technology. The service went live on the 14th, with expectations to significantly reduce consultation times and improve customer satisfaction.

The voice authentication technology deviates from traditional methods requiring direct questioning from call center agents, instead encrypting each individual’s unique vocal patterns. Upon customer agreement, this data is stored for secure, swift authentication in future calls, minimizing the need for repeated security questions.

After passing rigorous testing, including the Financial Security Institute’s performance evaluations in bio-information distributed management and biometric authentication, it’s proven to be a suitable and highly efficient verification method.

Guarding Against Identity Theft Through Advanced Detection
Addressing concerns of voice imitation through deepfake technologies, KT has integrated detection systems to strengthen security. The business plans to continuously refine the quality of voice authentication to stay ahead of emerging threats.

Jun-ki Choi, Executive Vice President of KT’s AI Business Division, stated that the new voice authentication service had already shown tangible efficiency gains, reducing call duration by 19 seconds at KT’s 100 call center. He emphasized KT’s commitment as an ‘AI Innovation Partner’ to further solidify security measures and support organizations in delivering superior citizen-focused services.

Artificial Intelligence in Customer Service
Voice authentication AI service, such as the one introduced by KT at the National Health Insurance Service (NHIS) Center in South Korea, represents a growing trend in the application of AI technologies to enhance customer service experiences. This development occurs in a global context where organizations are increasingly turning to AI to provide faster and more secure services.

Important Questions and Answers:
1. How does voice authentication AI improve customer service?
Voice authentication AI improves customer service by speeding up the identification process, reducing wait times, and minimizing the potential for human error in verifying identities.

2. What are the security measures against voice imitation?
KT has integrated advanced detection systems to counteract voice imitation threats, including those posed by deepfake technologies. This includes analyzing voice patterns for authenticity.

3. Can voice biometrics be considered secure?
Yes, with rigorous testing and performance evaluations, voice biometrics can be highly secure. However, like all systems, it must continuously be updated to protect against new threats.

Key Challenges and Controversies:
One of the key challenges of voice authentication technology is ensuring the privacy of customers’ biometric data. The potential for voice imitation or spoofing through advanced technologies is a concern that providers must address. The ethical use of biometrics for customer identification, providing opt-in options, and safeguarding stored biometric data are essential to maintaining consumer trust.

Advantages and Disadvantages:
Advantages of voice authentication AI services include enhanced customer convenience, reduction in service time, improved security over traditional password systems, and contactless verification. Disadvantages may encompass privacy concerns, the necessity for a high-quality voice recording environment, the potential exclusion of individuals with speech impairments or accents, and the risk of sophisticated voice spoofing attacks.
