After completing his doctorate, Leemann held postdoctoral positions at the Universities of Bern and Zurich. In 2014, he joined the University of Cambridge as a postdoctoral researcher, working, among other topics, on dialect variation in British English. He was appointed Assistant Professor at Lancaster University in 2017, the same year he completed his venia docendi at the University of Zurich. In 2019, Leemann was awarded an SNSF Eccellenza Professorial Fellowship, enabling him to establish his own research group at the University of Bern. He became a full professor there in 2022 and co-director of the Institute of Germanic Languages and Literatures.[3]
Research and contributions
Swiss German dialectology
In 2013, Leemann launched the Dialäkt Äpp, a smartphone app that predicted users' regional origins based on their dialectal word choices and pronunciation.[4] The app attracted over 100,000 participants and laid the groundwork for a broader investigation into Swiss German dialect change. In 2019, his SNSF-funded project SDATS (Swiss German Dialects Across Time and Space) combined historical data with new interviews from more than 1,000 speakers. This resulted in the publication of the Dialäktatlas – 1950 bis heute in 2025, a comprehensive atlas that maps over 160 linguistic features across Switzerland, illustrating both change and continuity.[5][non-primary source needed]
German dialects in Europe
Leemann also co-led a large-scale study of dialects in Germany, Austria, and Switzerland. In collaboration with Spiegel Online and Tages-Anzeiger, he launched an online dialect quiz titled "Grüezi, Moin, Servus", which attracted over 770,000 participants. The study showed regional dialect leveling in northern German-speaking areas and persistent differences between East and West Germany, even decades after reunification.[6][7][8]
English dialectology
At Cambridge, Leemann contributed to the development of the English Dialects App (EDA), released in 2016.[9] The app used user responses to predict their regional origin and collected over 30,000 data points. This data formed the English Dialects App Corpus (EDAC), one of the largest contemporary databases on British English dialects. The findings, published in Ampersand (2018), highlighted ongoing dialect leveling and increasing influence from London English, though some local accents, particularly in the northeast of England, remained resilient.[10]
Sociophonetics and forensic phonetics
Leemann's research extends to sociophonetic factors such as how age, mobility, and personality correlate with speech variation. He has explored voice perception and speaker identification, including studies involving voice cloning and deepfake audio to simulate speech for analysis.[11][12] In 2024, he co-authored An Introduction to Forensic Phonetics and Forensic Linguistics, bridging theoretical phonetics with practical applications in legal contexts.[13]

Awards and recognition
Leemann received the CHF 1.62 million SNSF Eccellenza Professorial Fellowship in 2019, awarded to outstanding early-career researchers.[14][15] He has also received funding for projects related to dialect sound aesthetics and public linguistic engagement.[16][17]
Public engagement and media
Leemann's work has reached broad audiences via interactive apps, media partnerships, and science communication. The Dialäkt Äpp and EDA brought linguistic research to tens of thousands of users. His dialect studies have been featured in Spiegel Online, The Guardian, BBC News, and Swiss National Radio.[18][19][20] He frequently contributes to public lectures and media programs, promoting awareness of dialect diversity.[21]
