Several members of CAL participated in the annual Mechanical and Mechatronics Engineering Postgraduate Conference, organised by the department on 14 April 2025.

Our Master’s and PhD students delivered presentations on a variety of research topics, including speech perception, multi-drone auditory systems, virtual acoustics, high-variability phonetic training, and listening effort.

Jenice Sunny KuzhikombilJenice presented research on how vowel duration and stress influence the identification of Māori short and long vowels across different acoustic environments.

Mingxue SongMingxue presented a proposal for a multi-drone system with distributed semi-blind source separation to enhance audio signals for drone-mounted microphone arrays.

Junda LiJunda presented an investigation on the impact of age on speech perception and listening effort in virtual environments, focusing on older users and acoustic environment differences.

Xin WangXin presented research on the effects of high-variability phonetic training on vowel length identification for second-language listeners in various acoustic environments.

Epri Wahyu PratiwiEpri presented an investigation into how acoustic environments, vocoded speech, and language familiarity affect speech intelligibility and listening effort, particularly for cochlear implant users.
