Team member Lorenzo Maselli is currently back in Central African Republic, continuing the fieldwork started last year as part of a broader postdoctoral research programme on phonetic and phonological microvariation in the Ubangi region. This new field mission builds directly on the 2025 campaign, during which Lorenzo collected a rich body of electroglottographic (EGG) and other articulatory data. The present stay focuses on extending and consolidating these recordings, with particular attention to tone in the Bantu language Mpiemo. A first set of results from this year’s EGG recordings will be presented later this year at the 11th International Conference on Bantu Languages (Bantu11). Together, these field campaigns aim to establish a robust empirical foundation for integrating phonetic evidence into historical and typological research on Central African languages.
