In collaboration with the University of Cologne, the Speech Sound Variability Research Group investigates the articulatory and acoustic variability of speech sounds across different speech modes, speaking styles, and phonetic contexts. So far, the group’s research has primarily focused on the variability of vowels and examined both within- and between-speech-stream determinants of this variability.

The collaboration is led on the Hungarian side by Andrea Deme (formerly led by Alexandra Markó), and on the German side by Prof. Dr. Reinhold Greisbach (University of Cologne).

The research has been supported multiple times by mobility cooperation grants of TKA (Tempus Public Foundation, Hungary) and DAAD (German Academic Exchange Service, Germany), and invidivdual grants.
