Generalized Fast On-the-fly Com WFST-Based Speech R

Abstract

This paper describes a Generalized Fast On-the-fly Composition (GFOC) algorithm for Weighted Finite-State Transducers (WFSTs) in speech recognition. We already proposed the original version of GFOC, which yields fast and memory-efficient decoding using two WFSTs. GFOC enables fast on-the-fly composition of three or more WFSTs during decoding. In many cases… (More)
