<p>Hannah White and her colleagues at Macquarie University researched how creaky voice is reflected in Australian English used in Sydney, and what factors influence its prevalence. The team used conversation samples from high school students across Sydney and employed algorithms to automatically identify creaky voice, and their results reveal that the area a speaker lives, and its diversity, are some of the most significant factors determining creaky voice use.</p>

<p>Phoebe Peng, an Engineering Honours student at the University of Sydney, is researching ways to allow people with low vision and blindness to play pingpong using sound. The process uses neuromorphic cameras and an array of loudspeakers, designed to allow players to track the ball and movements based on sound. Using two perfectly positioned cameras, Peng could identify and track a ball in 3D in real time. She then fed that data into an algorithm controlling loudspeakers along the sides of the table, which created a sound field matching the position of the ball.</p>

<p>Parag Chitnis of George Mason University led a team that developed a wearable ultrasound system that can produce clinically relevant information about muscle function during dynamic physical activity. The system uses a patented approach that uses long-duration chirps and ultrasound sensing, and it allowed the team to design a simpler, cheaper system that could be miniaturized and powered by batteries. The result is an ultrasound monitor with a small, portable form factor that can be attached to a patient.</p>
