Word Segmentation on Discovered Phone Units with Dynamic Programming and Self-Supervised Scoring. (arXiv:2202.11929v1 [cs.CL])

Recent work on unsupervised speech segmentation has used self-supervised
models with a phone segmentation module and a word segmentation module that are
trained jointly. This paper compares this joint methodology with an older idea:
bottom-up phone-like unit discovery is performed first, and symbolic word
segmentation is then performed on top of the discovered units (without
influencing the lower level). I specifically describe a duration-penalized
dynamic programming (DPDP) procedure that can be used for either phone or word
segmentation by changing …
