On May 21, 2023, 42dot, the software center of Hyundai Motor Group, unveiled Gleo AI, a sophisticated in-vehicle voice AI agent aimed at enhancing driver and passenger interactions with their vehicles. Built on large language model (LLM) technology, Gleo AI allows for more natural conversations, enabling users to control in-car functions like navigation, climate, and media through voice commands. Unlike traditional voice assistants, Gleo AI comprehends conversational context, driving conditions, and the speaker's location within the vehicle, allowing it to combine various AI agents for effective command execution. The system prioritizes safety by processing critical vehicle controls with on-device AI, ensuring quick responses and reliability. Additionally, 42dot has developed proprietary voice technologies tailored for driving environments, including multilingual speech recognition and advanced text-to-speech systems. The company plans to continuously enhance Gleo AI with over-the-air updates, aiming to evolve it into a personalized mobility companion that anticipates user needs. This innovation highlights the growing importance of in-vehicle AI agents in the software-defined vehicle market, as they integrate vehicle controls with personalized services.
