This book introduces the theory, algorithms, and implementation techniques for efficient decoding in speech recognition mainly focusing on the Weighted Finite-State Transducer (WFST) approach. lattice. The practical implementation of the method is based on the weighted finite-state transducers (WFST) as a convenient tool for hypothesis presentation, integrated in Kaldi toolkit [15]. The weighted finite-state transducers are now widely used in application to different speech recognition algorithms that form the basis of statistical speech recognition, this class will also M.

This talk describes a weighted finite-state transducer composition algorithm that generalizes This filtering permits the composition of very large speech recognition offline composition of the recognition transducer in an FST-based decoder. This paper proposes a new on-the-fly composition algorithm for Weighted Finite-State Transducers (WFSTs) in large-vocabulary continuous-speech recognition. In general on-the-fly composition, two transducers are composed during decoding, and a Viterbi search is performed based on the composed search space. In this new PyKaldi2 is a speech toolkit that is built based on Kaldi and PyTorch. Openlat includes detailed descriptions of the library API, the algorithms used and the combining, optimizing, and searching weighted finite-state transducers (FSTs).

Thus, weighted finite-state transducers define a common framework with shared algorithms for the representation and use of the models in speech recognition that has important algorithmic and software engineering benefits.
