The AI voicebot handles multiple enquiries simultaneously, reducing customer wait times and enhancing operational efficiency.

Our team has contributed to the design and implementation of the hotline service for the Heavy Rail Stations. Since Hong Kong Cantonese is heavily code-mixed, training the voicebot to decipher the questions is challenging. Empowered by the suitable Large Language Model, AI prompt engineering and ongoing knowledge database training, it can recognise local dialects and handle enquiries with the correct information drawn from other systems and/ or databases.

This project has won a gold medal at the International Exhibition of Inventions Geneva 2026.
