4-Mic 60-Degree Directional Pickup Microphone Array Debuts at the 2025 Osaka World Expo

HAOKAI TechnologyOsaka, Japan

In the “Future Society Playground” at the EF booth, the AI digital human captured visitors’ speech in real time through the 4-mic array microphone, combining virtual scenes with physical exhibits to interpret the themes of “healthy living” and “sustainable development”. For example, visitors discussed carbon neutrality technologies with the digital human, or controlled a virtual ecosystem model with voice commands. In the specially designed “Anime Culture Interaction Zone”, the digital human, rendered in a Japanese anime-style persona, talked with visitors and precisely recognized dialects and buzzwords, setting off wave after wave of “Sugoi!” exclamations among the audience. This innovative format not only demonstrated technical strength but also deeply matched local Japanese cultural preferences. Beyond the booth, EF technology was also applied in scenarios such as the China pavilion and corporate forums, for example providing 24-hour intelligent guidance for government reception and real-time interpretation and speech transcription for international conferences, significantly improving service efficiency.

Taking the 2025 Osaka World Expo as its stage, the EF digital human engine company showed the world the limitless possibilities of technological humanism — when precise voice capture meets intelligent emotional interaction, technology is no longer a cold tool, but a bridge connecting past and future, East and West. This breakthrough result won high recognition from on-site visitors and heralds the arrival of a new era of human-machine collaboration.
