The GTM-UVIGO System for Albayzin 2018 Speech-to-Text Evaluation

Laura Docío-Fernández, Carmen García-Mateo

This paper describes the Speech-to-Text system developed by the Multimedia Technologies Group (GTM) of the atlanTTic research center at the University of Vigo, for the Albayzin Speech-to-Text Challenge (S2T) organized in the Iberspeech 2018 conference. The large vocabulary automatic speech recognition system is built using the Kaldi toolkit. It uses an hybrid Deep Neural Network - Hidden Markov Model (DNN-HMM) for acoustic modeling, and a rescoring of a trigram based word-lattices, obtained in a first decoding stage, with a fourgram language model or a language model based on a recurrent neural network. The system was evaluated only on the open set training condition.
