Spoken Language Processing and Modeling for Aviation Communications
… natural language processing, such as N-grams and word lattices. This thesis experiments with a process for pretraining transformer-based language models on aviation English corpora and compare the effectiveness and performance of language models transfer learned from pretrained checkpoints and …

Combining natural language processing systems to improve machine translation of speech
… to process ambiguous ASR output in the form of word lattices. A novel algorithm for lattice-based translation is proposed that allows for exhaustive, but efficient phrase-level reordering in the search. Experimental results show that significant improvements in translation quality can be …

Spoken Language Understanding: from Spoken Utterances to Semantic Structures
… based on transducers are also amenable to decode word lattices generated by large vocabulary speech recognizers. We show the benefit of our approach with comparative experiments among generative, discriminative and joint models on some of the most representative corpora of SLU, for a total of four …

Discriminative training and acoustic modeling for automatic speech recognition
… recently proposed as, for example, the Minimum Word Error (MWE) criterion and the closely related Minimum Phone Error (MPE) criterion. The new approach allows for investigating a large number of different training criteria within a single framework and thus to yield consistent analytical and …
