Delimited smoothing technique over pruned and not pruned syntactic language models : perplexity and WER


Continuous Speech Recognition (CSR) systems require a Language Model (LM) to represent the syntactic constraints of the language. A sub-class of the regular languages, the k Testable in the Strict Sense (k-TSS) languages, has been used to generate LMs. Then, a smoothing technique needs to be applied to also consider events not represented in the training… (More)
