Research Areas

My work focuses on the fine phonetic detail of spoken interaction between humans and computers with the aim of making this information usable for the further development of voice-activated digital assistants. In particular, I am researching accommodation phenomena and the perception of natural and synthetic voices by human users of such assistants. I have also gained expertise in the field of explainable artifcial intelligence (XAI) by analyzing speech embeddings generated by state-of-the-art automatic speech recognition (ASR) models for phonetic information. Lately, I have been researching the prosody of heritage speakers of a critically endangered language. (Last update: Feb 12, 2026)
