    abstract = "Phonetic transcription requires significant time and expert training. Automated, state-of-the-art text-dependent methods still involve substantial pre-training annotation labor and may not generalize to multiple languages. Hallucination of speech amid silence or non-speech noise can also plague these methods, which fall short in real-time applications due to post hoc whole-phrase evaluation. This paper introduces Phonotomizer, a compact, unsupervised, online training approach to automatic, multilingual phonetic segmentation, a critical first stage in transcription. Unlike prior approaches, Phonotomizer trains on raw sound files alone and can modulate computational exactness. Preliminary evaluations on Irish and Twi, two underrepresented languages, exhibit segmentation comparable to current forced alignment technology, reducing acoustic model size and minimizing training epochs."
