    Assessed and Annotated Vowel Lengths in Spoken Icelandic Sentences for L1 and L2 Speakers: A Resource for Pronunciation Training
    (University of Tartu Library, 2025-03) Richter, Caitlin Laura; Friðriksdóttir, Kolbrún; Bergsson, Kormákur Logi; Maher, Erik Anders; Benediktsdóttir, Ragnheiður María; Gudnason, Jon; Johansson, Richard; Stymne, Sara
    We introduce a dataset of time-aligned phonetic transcriptions focusing on vowel length (quantity) in Icelandic. Ultimately, this aims to support computer assisted pronunciation training (CAPT) software, to automatically assess length and possible errors in Icelandic learners' pronunciations. The dataset contains a range of long and short vowel targets, including the first acoustic description of quantity in non-native Icelandic. Evaluations assess how manual annotations and automatic forced alignment characterise quantity contrasts. Initial analyses also imply partial acquisition of phonologically conditioned quantity alternations by non-native speakers.

    Mapping Faroese in the Multilingual Representation Space: Insights for ASR Model Optimization
    (University of Tartu Library, 2025-03) Lág, Dávid í; Scalvini, Barbara; Gudnason, Jon; Johansson, Richard; Stymne, Sara
    ASR development for low-resource languages like Faroese faces significant challenges due to the scarcity of large, diverse datasets. While fine-tuning multilingual models using related languages is a common practice, there is no standardized method for selecting these auxiliary languages, leading to a computationally expensive trial-and-error process. By analyzing Faroese’s positioning among other languages in wav2vec2’s multilingual representation space, we find that Faroese's closest neighbors are influenced not only by linguistic similarity but also by historical, phonetic, and cultural factors. These findings open new avenues for auxiliary language selection to improve Faroese ASR and underscore the potential value of data-driven factors in ASR fine-tuning.
