NUGU, the name of both the speaker and the AI platform, uses a cloud-based deep-learning framework that increases its speech recognition accuracy over time.
The mobile carrier said over 130 million conversations have been stored in its cloud server. Voice recognition rate for both children and regional Korean dialects significantly increased since launching, it said.
NUGU Mini weighs 219 grams -- almost a fifth of NUGU's 1,030 grams -- and can connect to external speakers and a battery that lasts over four hours.
Users can turn on Melon, Korea's number one music streamer, use smart home features offered by SK Telecom, and control their set-top boxes.
They can also order food, manage schedules, check for weather and traffic information, enquire about currency exchange rates, and register to visit local bank branches.
NUGU Mini will cost 99,000 won ($87) but SK Telecom will offer it for 49,900 won for three months when sales begin August 11.
