WebASR Inference with CTC Decoder. This tutorial shows how to perform speech recognition inference using a CTC beam search decoder with lexicon constraint and KenLM … Webused. Furthermore, since CTC integrates out over all pos-sible input-output alignments, no forced alignment is re-quired to provide training targets. The combination of bidi-rectional LSTM and CTC has been applied to character-level speech recognition before (Eyben et al.,2009), how-ever the relatively shallow architecture used in that work
