Less Peaky and More Accurate CTC Forced Alignment by Label Priors
ICASSP 2024accepted
Connectionist temporal classification (CTC) models are known to have peaky output distributions. Such behavior is not a problem for automatic speech recognition (ASR), but it can cause inaccurate forced alignments (FA), especially at finer granularity, e.g., phoneme level. This paper aims at allevia…
