Automatic Speech Recognition using Machine Learning Techniques

A significant problem in machine learning is automatic voice recognition, particularly continuous speech recognition with a vast vocabulary. The standard speech recognition framework has been the hidden Markov model (HMM)-Gaussian mixed model (GMM) for a long time. However, more recently, the performance of the HMM-deep neural network (DNN) model and the end-to-end model employing deep learning has surpassed that of the HMM-GMM.
