Long short-term memory language models with additive morphological features for automatic speech recognition
2015
2015 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Models of morphologically rich languages suffer from data sparsity when words are treated as atomic units. Word-based language models cannot transfer knowledge from common word forms to rarer variant forms. Learning a continuous vector representation of each morpheme allows a compositional model to represent a word as the sum of its constituent morphemes' vectors. Rare and unknown words containing common morphemes can thus be represented with greater fidelity despite their sparsity. Our novel
