I'm Martijn Bartelds, a PhD candidate in the Computational Linguistics department at the University of Groningen, advised by Martijn Wieling and Mark Liberman.

My research focuses on developing and applying natural language processing methods to model resource-scarce languages. I am particularly interested in speech processing with extremely low-resource languages, dialects, and non-native speech. Currently, I am visiting the Stanford NLP group where I am advised by Professor Dan Jurafsky.

Updates:

• I was awarded a Prins Bernhard Cultuurfonds scholarship to visit Stanford University and the University of Pennsylvania
• Our paper Quantifying Language Variation Acoustically with Few Resources was accepted at NAACL 2022
• Our paper Automated speech tools for helping communities process restricted-access corpora for language revival efforts was accepted at ComputEL-5
• Our paper Neural Representations for Modeling Variation in Speech was accepted at Journal of Phonetics
• Since October 2021, I am a visiting member of staff in Odette Scharenborg's lab at Delft University of Technology
