UltraFest IX

Ultrasound Imaging for Speech and Language

Virtual Conference

October 21-24, 2020





Following up on the great scientific meeting of UltraFest VIII, hosted by Dr. Aude Noiray and colleagues in Potsdam, Germany, in 2017, we invite you to participate in UltraFest IX, the 9th meeting of researchers interested in ultrasound imaging for speech and language.




Registration is $100 ($50 for students). Anyone who was a student in May 2020 can take advantage of the student rate.  Registration will remain open through the last day of the conference.


Registration is closed.




UltraFest IX will take place virtually, using the Whova and Gather platforms.  All oral presentations and Master Classes will be live using Zoom embedded within the conference Whova website.  All poster presentations and social events will be live using the conference Gather website.
