Anna Persson

Anna Persson is a Senior Lecturer at the Department of Swedish Language and Multilingualism, Stockholm University, specializing in bilingualism and speech perception research. Her work bridges acoustic analysis, perception experiments, and computational models to understand cross-talker phonetic variability.

Key research themes include:

• Pre-linguistic normalization mechanisms in speech processing
• Formant dynamics and vowel perception in Central Swedish
• Cognitive adaptation to second-language speech

Recent publications analyze normalization theories against Swedish vowel spaces (2023) and computational models of English vowel perception (2025). She teaches psycholinguistics, Swedish language assessment, and university preparation courses.

Her acoustic studies reveal:

• Primary role of F1, F2, and vowel duration in Swedish vowel identification
• Significance of formant movements in diphthongization
• Third-formant contributions to lip-rounding contrasts

Persson's work emphasizes open-access frameworks like SwehVd vowel database and Bayesian modeling tools for unbiased normalization theory evaluation.
