Equivalence of Segmental and Neural Transducer Modeling: A Proof of Concept

no code implementations13 Apr 2021 Wei Zhou, Albert Zeyer, André Merboldt, Ralf Schlüter, Hermann Ney

With the advent of direct models in automatic speech recognition (ASR), the formerly prevalent frame-wise acoustic modeling based on hidden Markov models (HMM) diversified into a number of modeling architectures like encoder-decoder attention models, transducer models and segmental models (direct HMM).

A New Training Pipeline for an Improved Neural Transducer

1 code implementation19 May 2020 Albert Zeyer, André Merboldt, Ralf Schlüter, Hermann Ney

We compare the original training criterion with the full marginalization over all alignments, to the commonly used maximum approximation, which simplifies, improves and speeds up our training.
