ESTsoft has greatly improved the quality and convenience of its AI human services through advanced AI human service development.

AI service specialist ESTsoft (CEO Jung Sang-won) announced on the 21st that it is launching a new version of Han Ji-a, the AI Analyst for Korea Investment & Securities.

Han Ji-a is the AI Human representative of Korea Investment & Securities. Born in December last year through ESTsoft's AI Persona technology that can create a non-existent, entirely new virtual persona, Han Ji-a is currently active in two corners, 'Show Me the Report' and 'Three-Minute Overseas Stock Fighter', introducing the market analysis reports of Korea Investment & Securities.

The AI Human Han Ji-a has produced more than 550 pieces of content in the last six months, proving the usability of ESTsoft's AI Human. Korea Investment & Securities plans to actively utilize Han Ji-a in investment basic education content and more in the future.

In this enhanced version of Han Ji-a introduced by both companies after about six months, new features have been added, such as ESTsoft's improved global best-level voice conversion technology TTS (Text to Speech) and new costume options.

In this enhancement work, both companies concentrated on refining TTS as Han Ji-a's activities demand a high level of vocabulary usage that is utilized in various fields such as securities, economics, and industries, and added new voices that can produce a different atmosphere during voice emissions.

Furthermore, the video editing function has also been improved to be optimized for mobile and SNS environments. Considering the environment of video platforms such as YouTube Shorts and Meta Reels, they added functions that can adjust the screen ratio and video playback speed. By utilizing these functions, production of vertical (9:16) videos as well as fast-paced videos that fit shorter playtimes becomes easier.

With this enhancement work, ESTsoft has achieved service improvements such as strengthening AI human voice emission quality, adding costume options, and mobile optimization, and has also further strengthened the competitiveness of its AI Human and video production solution 'AI Studio Persona'.

Director Byeon Kye-pung of ESTsoft AI Division stated, "The goal of this enhancement work was to maximize the practical effect of AI Human by complex use of strengthened TTS voice technology and expanded content factors on top of the existing hyper-realistic portraits, thereby securing a super-gap competitive advantage," and "As we have sufficiently proven the practical usability of AI Human even in the global market and have enhanced it, we will make every effort to globalize AI human services by more actively utilizing Microsoft's multilingual voice conversion technology that we have successfully integrated recently."

Meanwhile, the new version of the AI Human Analyst Han Ji-a can be checked at the existing stages of Korea Investment & Securities 'Show Me the Report' and 'Three-Minute Overseas Stock Fighter'.
