AI agent assistance and voice authentication in customer centers

KTcs used AI agent assistance and voice authentication, with identification reportedly falling to 5 seconds

WorkingCompany's own claim

Problem

Customer-service agents had to search for answers while listening to callers. Returning customers also faced identification procedures before continuing their enquiries.

Approach

At KTcs's Dongjak 2 center, KT's AI Genie transcribed calls and surfaced relevant information for agents. It classified enquiries and prepared summaries after calls. Voice authentication recognized returning callers without requiring them to enter identification information again.

Results

5 secondsreported identification time with voice authentication, compared with 24 seconds previouslyCompany's own claim[1]

Takeaway

The deployment supported agents during calls and reduced work between calls. The identification-time figure concerned authentication rather than total handling time.
