Report from Ultrafest and Haskins Labs
Pam Beddor, Andries Coetzee, and Kevin McGowan have recently returned from NYU where they attended Ultrafest IV. As previously mentioned here, Ultrafest is an annual opportunity for linguists and speech scientists using ultrasound to get together, share work they’re doing with this relatively new tool and discuss common solutions to ultrasound’s unique challenges. We learned a great deal about how ultrasound is used, what its strengths are, and what challenges we can expect to face as we move in this new direction. The department is now researching ultrasound hardware options and will be reviewing demonstration models soon.
Pam and Kevin also had the opportunity to visit the new home of Haskins Laboratories where Pam gave an invited talk on “The phonetics and phonology of nasal gestures” as part of the Haskins Staff Talk series.
During the visit they toured the facilities and were given a hands (and chins)-on introduction to HOCUS (the Haskins Optically-Corrected Ultrasound System) — a bold, multi-year project at Haskins to use optical tracking to allow free and natural head motion during analysis of running speech while still providing the data necessary to orient ultrasound images to the location of the passive articulators in four dimensions.
“Ultrasound systems for research in linguistics range from compact laptop-sized units one can take into the field to finely-tuned installations such as those at Haskins or Maureen Stone’s lab at the University of Maryland, Baltimore“, Kevin reported. “This trip will definitely let us take advantage of others’ experiences with ultrasound as we add this tool to our own lab.”
