Recognition of second language speech is still a challenging task even for state-of-the-art automatic speech recognition (ASR) systems. Considering that second language speech usually includes less fluent pronunciation and mispronunciation even when it is grammatically correct, we propose a novel phonetic decision tree (PDT) method considering integrated acoustic and linguistic features to deri...

Student-teacher training allows a large teacher model or ensemble of teachers to be compressed into a single student model, for the purpose of efficient decoding. However, current approaches in automatic speech recognition assume that the state clusters, often defined by Phonetic Decision Trees (PDT), are the same across all models. This limits the diversity that can be captured within the ense...

Abstract. Construction progress monitoring is an important process throughout the project timeline towards its successful completion. Among imaging techniques, photogrammetry considered as economical and effective method. However, few studies can be found on construction via photogrammetry; thus, not much guideline available for this domain. This study evaluated tools assessment of rebar grid f...
