Human expertise and AI collaboration fuel unexpected industry growth

The interpretation and translation industry—once deemed the most vulnerable to tools like ChatGPT—is experiencing robust expansion. Rather than replacing human professionals, generative AI has become an ally, deepening expertise and inspiring a wave of startups that leverage translators’ nuanced skills.

Industry Growth Amid Generative AI Hype

According to Statistics Korea, registered translation companies rose from 2,429 in 2020 to 2,805 in 2023, while the workforce grew from 6,251 to 6,712 over the same period. Although 2024 data are pending, insiders predict both figures will reach record highs this year—evidence that demand for human-led language services remains strong even as basic machine-translation tools proliferate.

Context and Nuance Remain Human Strengths

“AI can parse surface meaning, but it struggles with cultural context and emotional nuance,” says Kim Woo-yeon, CEO of G&M. Lee Ju-yeon, professor at Hankuk University’s Graduate School of Interpretation and Translation, adds that legal, diplomatic and medical texts demand ethical judgment and situational awareness—capacities beyond current AI. Consequently, she predicts, “AI will not supplant interpreters’ work.”

High-Value Specializations and New Business Models

Many professionals now offload routine tasks to AI and concentrate on specialized, high-value projects. “We let ChatGPT handle basic translations and then focus on medical documentation, K-pop localization and technical manuals,” says an industry official. This mirrors healthcare trends, where diagnostic AI augments rather than replaces physicians, boosting workloads and revenues.

Innovative startups are emerging:

• Hansam Global (Korea’s only top-100 agency) is developing its own large-language model and AI-evaluation tools.

• Joel Localization integrates AI interpretation into apps like Notion.

• Plito supplies real-time, 38-language interpretation systems to IBK Industrial Bank’s foreign-service branches.

Global Expansion Fuels Demand

South Korean companies’ overseas growth has also driven demand. G&M reports rising contracts from SMEs and multinationals in markets beyond the U.S., China and Japan. The firm now handles rare European and Southeast Asian languages and provides on-site guides. “As K-beauty and K-food brands expand abroad, more small and midsize companies seek our services,” notes a G&M spokesperson.

Outlook

Far from fading, translation and interpretation professionals are strengthening their roles by embracing AI as a partner. With irreplaceable skills in nuance, ethics and cultural context, human linguists—and the startups they found—are well positioned for continued expansion in an increasingly interconnected world.
