South Korean telecom giant KT said Wednesday it will spend 300 billion won ($256 million) on developing advanced artificial intelligence technology by 2023 to expand its high-tech business at home and overseas.

During a press briefing at its Seoul headquarters, KT introduced a four-year investment plan on promoting its AI businesses. It also pledged to hire more than 1,000 AI experts to support the initiative.

Using its 5G wireless network and other technological prowess, KT said it would expand the business application of smart speaker Giga Genie. The voice recognition device is now being used for providing AI-assisted services in hotels and cars.

“Giga Genie is very popular not only in Korea but also overseas,” KT Vice President Lee Pil-Jae told reporters.“We hereby announce our makeover as an AI company, so that we may serve as the foundation for Korea’s future.”
