Morph-Based Speech Recognition and Modeling of Out-of-Vocabulary Words Across Languages
We explore the use of morph-based language models in large-vocabulary continuous speech recognition systems across four so-called “morphologically rich” languages: Finnish, Estonian, Turkish, and Egyptian Colloquial Arabic. The morphs are…
