Task-Specific Scorers

in majority of reading exercises which are included in the Primer we already know the text in advance

we already know what utterances could be considered as correct lectures and which not

to every specific exercise - like vowel or syllable recognition – Primer associates a specific language model (scorer) which constraints the connectionist temporal classification (CTC) beam search to restricted amount of exercise-relevant answers

significantly constraining the search space of plausible solutions

INNOVATION 1 : implementation of exercise-specific scorers transforms a generic ASR problem (difficult) into multi-class classification problem (easier)
