HiClub Inc. (Headquarters: Minato-ku, Tokyo; CEO: Yū Furuya) has officially launched a new voice generation feature called the 'Next-Gen Voice Model' in its conversational AI app 'SynClub' (available on iOS and Android), within the Immersive Mode.

This new model significantly improves voice quality, emotional expression, Japanese pronunciation, and stability during long-form speech generation, enabling more natural and realistic character voices. It enhances immersion in conversations with AI characters and in content creation.

Background

SynClub aims to lower the barriers to content creation by leveraging AI technology, enabling anyone to create manga, short animations, and character voice works through conversational interfaces. The previously offered 'Enhanced Voice Model (Plus Model)' has received high praise from users for its rich emotional expression and immersive experience.

However, users have also expressed the following requests:

- Achieve more human-like, natural voice quality and intonation - Improve the naturalness and accuracy of Japanese pronunciation - Maintain consistent quality during long-form narration and continuous conversations

In response to these needs, the new 'Next-Gen Voice Model' has been developed using the latest voice generation technology.
