Assistant professor

About me

Assistant professor since January 2019 at the Division of Speech and Language Pathology, Department of Clinical Science, Intervention and Technology at the Karolinska Institutet (KI).

Research description

The main focus in Sofia’s research is perception of pathological (or otherwise non-typical) speech – how speech is perceived by the speakers themselves, as well as by other listeners. This research involves perceptual instruments that – in contrast to traditional categorical measures – are sensitive to fine phonetic variation in listeners’ perception of non-typical speech.

An additional research focus are the communicative consequences of producing misarticulated speech, particularly with regards to intelligibility. This research involves listener evaluations performed in real-time, where listener reactions are registered during the continuous playback of connected speech. This method has been used for registering listener reactions to misarticulated speech in children, but also for the perceptual evaluation of speech recorded from speakers with acquired neurological conditions. By relating listener reactions to annotated events in the speech signal, this method could potentially address questions like ”which specific voice/speech problems contribute the most to unintelligibility?” or ”which specific voice/speech problems are most salient to naïve listeners?”. These instruments are used in the project Functional consequences of misarticulation in children's continuous speech.

Sofia also has a more broad interest in speech and language disorders in children, and how these may affect everyday life activities, such as when interacting with peers, family and others. Questions relating to this interest have mostly been investigated in student projects, under Sofia's supervision.

Teaching portfolio

Since 2016 responsible for various courses at the Study Program in Speech and Language Pathology; particularly involved in courses relating to children's typical and atypical speech and language acquisition. Supervises Master theses (30 credits, advanced level).

During 2014-2016 guest lecturer at the Department of linguistics and philology at Uppsala university.

Sofia’s post-doc project involved the pedagogical development of the Study Program in Speech and Language Pathology at the Karolinska Instiutet during 2014-2016. 


Earned her doctoral degree in April 2014 at the Royal Institute of Technology, Stockholm (KTH), with a thesis focusing on perceptual consequences of misarticulated speech in children – how these children’s speech are perceived by adult listeners and by the children themselves. Apart from her M.Sc degree in SLP (Lund, 2007), Sofia also has a M.Sc degree in computational linguistics (Uppsala, 2000).
