Text mining at multiple granularity: leveraging subwords, words, phrases, and sentences
… granularity. Operating on these fine-grained subwords addresses many important problems in NLP namely the long-tail data-sparsity problem whereby most words in a corpus are infrequent, and the more severe out-of-vocabulary problem. To effectively and efficiently mine these subword structures, …

Using graphone models in automatic speech recognition
… explores applications of joint letter-phoneme subwords, known as graphones, in several domains to enable detection and recognition of previously unknown words. For these experiments, graphones models are integrated into the SUMMIT speech recognition framework. First, graphones are applied to …

Subword segmental neural language generation for Nguni languages
… segmenter, showing that its learned subwords are closer to morphemes than standard subword tokens. Since SSLM is our first instantiation of subword segmental modelling, we present a detailed analysis of the architectural components and hyperparameters we found to be influential during …

Multilingual techniques for low resource automatic speech recognition
… need for text corpora, we investigate the use of subwords and web data which helps im- prove KWS spotting results. Finally, we reduce the need for speech recordings by using bottleneck (BN) features trained on multilingual corpora. We first propose the Low-rank Stacked Bottleneck architecture …
