Which features characterize speakers’ voices, and how are these features determined by what a speaker is saying?

This dissertation provides a formal description of the relationship between diatopic/diachronic micro-variation and phonologization through analysis of the phonetic/phonological properties of unstressed vowel reduction and vowel insertion in two Northern Italian dialects.

This dissertation examines what network in the human brain is involved in the perception of prosody and whether activity within this network is modulated by the personality trait alexithymia.

This project examines how speakers store and process regular pitch variation.

This study investigates the perception and production of emotional prosody by native and non-native listeners and speakers, i.e. Chinese and Dutch listeners and speakers, including Dutch L2 learners of Chinese.

How do we process language and speech? How do we integrate information at different levels – intonation, sentence structure, meaning, tone, words, sounds - and how does information at one level interact with information at another level?

I suggest a systematic study into the influence of non-singing female companions on vocal learning in young birds as a proof-of-principle study into how non-imitative learning processes from the social environment influence the timing and content of vocal learning and thus drive the interface between…

I am passionate about aquatic ecology, conservation and evolution, behavioural biology and global change. During my PhD, I am investigating the density and diversity of pelagic fish in and around offshore windfarms in the North Sea, more specifically related to the underwater acoustic conditions. This…

Dörner is interested in animal behaviour, neuroethology, ecology and anthropogenic effects on animal behaviour and species dynamics. The focus of her PhD is on the effects of light and noise pollution on migratory fish.

Academic studies or an academic career are a big challenge if you are deaf. Particularly in Africa, where many countries don’t even have secondary schools for the deaf. A team of Leiden academics has organised the first summer school for and by deaf academics on the African continent, in Ghana. We spoke…

Sonorous phenomena are always on the verge of becoming something else. As it unfolds, sound constitutes spaces, mediates presence, articulates time. Furthermore, it may prompt emotions, generate awareness, organise patterns of behaviour or trigger a sense of belonging. As sound becomes audible, it is…

This research aims to fully recall these lost sound aspects of the eighteenth century and is, therefore, a study that passionately advocates the diversity of musical experience in the context of historical performance practice.

Vincent van Heuven passed away unexpectedly on Friday 6 February 2026 at the age of 76 at his home in Kûbaard (Friesland), the Netherlands.

This thesis describes the development of a variety of mannosylated conjugates. Antigen presenting cells bear mannoside recognizing receptors that actively transport antigen into the cell. This thesis exploits this feature for the development of improved vaccines.

Man-made sounds in and around the oceans stress marine life and have an impact on marine species and ecosystems by changing the underwater acoustic climate. Hans Slabbekoorn from the Institute of Biology Leiden pleads for technical solutions to mitigate problems of noise pollution. Science review paper…

Hans Slabbekoorn, researcher at the Institute of Biology Leiden, is from the 16th to the 26th of July on board of the Pelagia, the Dutch national sea research vessel, which is currently on a collaborative mission for the National Initiative Changing Oceans (NICO).
