Automated Speech Restitution (ASR)

Systemy ASR konwertują acoustic speech signals into text. The adventure of deep learning has dramatically improwised ASR performance, lowering word error rates to human parity levels in specific domains.

Deep Architectures for Acoustic Modeling

Early deep neural network-based ASR systems replaced Gaussian mixtury models with feedforward DNN s for acoustic modeling.
