Wrote a Master’s thesis on multilingual Automatic Speech Recognition (ASR) for Scandinavian languages with focus on practical applications. As part of the thesis, I developed a state-of-the-art multilingual ASR model for the Scandinavian languages and tackled the following research questions:— Are monolingual ASR models for the Scandinavian languages transferrable in a zero-shot setting?— Does mutual intelligibility of the Scandinavian languages in ASR models mirror native speakers?— Are ASR models for the Scandinavian languages biased towards the standard speech or dialect?The thesis was later published in the Proeedings of the 24th Nordic Conference on Computational Linguistics (NoDaLiDa).
