The AI Call Secretary is an AI assistant service that answers and handles phone inquiries or requests on behalf of small business owners who cannot answer all incoming calls at their stores due to busy work schedules.


The newly launched Voice Styling service provides not only basic information such as business hours but also various promotional messages in distinctive voices. When a customer calls the store’s landline, the service uses text-to-speech (TTS) technology to synthesize AI voice with background music based on text pre-set through an app.


The Voice Styling service offers a total of five character voices that can be selected according to gender and mood. Users can adjust emotion, speed, and pitch, and set them together with the chosen greeting background music.


The provided character voices are linked with the AI technology of the ‘Typecast’ service, which has surpassed 1.75 million cumulative subscribers. KT plans to actively expand the AI ecosystem by collaborating with capable startups in the future.


To commemorate the launch of Voice Styling, KT is running a promotion offering the service free of charge for one month after subscription.



Choi Jun-gi, Executive Director of KT’s AI Business Division, said, “Voice Styling focuses on providing AI Call Secretary customers with unique and diverse character voices so that they can feel greater value and experience innovation and convenience in AI. We will continue to offer better services and features to AI Call Secretary users.”
