Frame-Level Specaugment for Deep Convolutional Neural Networks in Hybrid ASR Systems

2021

Inspired by SpecAugment - a data augmentation method for end-to-end ASR systems, we propose a frame-level SpecAugment method (f-SpecAugment) to improve the performance of deep convolutional neural networks (CNN) for hybrid HMM based ASR systems. …
