This work is aimed at exploring semi-supervised learning techniques to improve the performance of Automatic Speech Recognition systems. Semi-supervised learning takes advantage of unlabeled data in order to improve the quality of the representations extracted from the data.The proposed model is a neural network where the weights are updated by minimizing the weighted sum of a supervised and an unsupervised cost function, simultaneously. These costs are evaluated on the labeled and unlabeled portions of the data set, respectively. The combined cost is optimized through mini-batch stochastic gradient descent via standard backpropagation.The model was tested on a phone classification task on the TIMIT American English data set and on a written...
