Swiss German has no standard orthography, with a significant variation in its written form. To alleviate the uncertainty associated with this variability, we automatically generate a lexicon from which multiple written forms of a given word in any dialect can be generated. The lexicon is built from a small (incomplete) handcrafted lexicon designed by linguistic experts and contains forms of common words in various Swiss German dialects. We exploit the powerful speech representation of self-supervised acoustic pre-training (wav2vec) to address the low-resource nature of the spoken dialects. The proposed approach results in an overall relative improvement of $9\%$ word error rate compared to one based on an expert-generated lexicon for our TV Box voice assistant application.}, pdf = {https://publications.idiap.ch/attachments/papers/2022/Khosravani_INTERSPEECH_2021.pdf} }
