End-to-End Training of a Large Vocabulary End-to-End Speech Recognition System
End-to-End Training of a Large Vocabulary End-to-End Speech Recognition System
In this paper, we present an end-to-end training framework for building state-of-the-art end-to-end speech recognition systems. Our training system utilizes a cluster of Central Processing Units (CPUs) and Graphics Processing Units (GPUs). The entire data reading, large scale data augmentation, neural network parameter updates are all performed "on-the-fly". We use …
