TL;DR: A large vocabulary speech recognition system that is accurate, has low latency, and yet has a small enough memory and computational footprint to run faster than real-time on a Nexus 5 Android smartphone is described.
Proceedings ArticleDOI
Speech recognition techniques for a sign language recognition system.
TL;DR: This work presents their approach where the system developed is able to recognize sentences of continuous sign language independent of the speaker, and focuses on feature and model combination techniques applied in ASR, and the usage of pronunciation and language models (LM) in sign language.
