Published by Springer | 2014 | Automatic Speech Recognition --- A Deep Learning Approach edition
In this chapter, we summarize the book by rst listing and analyzing what we view as major milestone studies in the recent history of developing the deep learning based ASR techniques and systems. We describe the motivations of these studies, the innovations they have engendered, the improvements they have provided, and the impacts they have generated. In this road map, we will rst cover the historical context in which the DNN technology made inroad into ASR around 2009 resulting from academic and industry collaborations. Then we select seven main themes in which innovations ourished across-the-board in ASR industry and academic research after the early debut of DNNs. Finally, our belief is provided on the current state of the art of speech recognition systems, and we also discuss our thoughts and analysis on the future research directions
