Linkage between KT GIGA Genie and

‘AI Speaker’ which allows people to experience AI technologies easily in everyday life has been introduced throughout the world. Beginning with ‘Echo’ introduced by Amazon based on its AI secretary Alexa in 2014, the relevant market is growing rapidly throughout the world.

In our country, three mobile carriers, including KT, SK Telecom and LG Uplus are leading the AI speaker market and this market is growing rapidly although the market is a latecomer in comparison to markets in major countries that are led by global Internet companies, countries such as North America. Among these mobile carriers, KT is the No. 1 company in the domestic AI speaker market with 1.5 million subscribers. After the introduction of AI speaker ‘GIGA Genie’ in January 2017, KT is diversifying its product lines into GIGA Genie LTE, GIGA Genie Buddy, GIGA Genie 2 and AI Makers Kit.

GIGA Genie operates in close linkage with each home service platform (IPTV, music, phone call, home IoT) of KT and is linked with the third parties’ platforms, composing an overall AI ecosystem. Among the third parties’ platforms, GIGA Genie is linked with Saltlux’s platform for advancing dialog quality between a user and AI, and GIGA Genie provides a lifelike Deep Q &A service that requires extensive knowledge within such a linkage.
