This year our research group joins World Voice Day with a scientific outreach event
targeting high school students.

Technology and Economics Department of Telecommunications and Media Informatics , az MTA Commity of Acoustic Complex /AKB/)

Prof. dr. Tamás Hacki, habil. (Medical University of Regensburg, Semmelweis University, Eötvös Loránd University)
give talks on speech production and hearing,
while the ELTE Pro Musica choir provides the vivid illustration of the beauties of the voice.
In the second half of the program the students get a hands-on introduction to the acoustic analysis of speech and how the tongue ultrasound works, and they can try their knowledge on speech and hearing in a quiz.
