Significant ASR Error Detection for Conversational Voice Assistants

ICASSP 2024accepted

Modern Automatic Speech Recognition (ASR) systems are evaluated with respect to Word Error Rate (WER). While WER is a useful metric for training and evaluation of speech models, it does not fully reflect the difference in semantics between predicted and ground truth transcriptions. In conversational…

Federated Self-Learning with Weak Supervision for Speech Recognition

ICASSP 2023accepted

Automatic speech recognition (ASR) models with low-footprint are increasingly being deployed on edge devices for conversational agents, which enhances privacy. We study the problem of federated continual incremental learning for recurrent neural network-transducer (RNN-T) ASR models in the privacy-e…

Combating Label Noise in Deep Learning using Abstention

ICML 2019oral

We introduce a novel method to combat label noise when training deep neural networks for classification. We propose a loss function that permits abstention during training thereby allowing the DNN to abstain on confusing samples while continuing to learn and improve classification performance on the…

On Mixup Training: Improved Calibration and Predictive Uncertainty for Deep Neural Networks

NeurIPS 2019poster

Mixup~\cite{zhang2017mixup} is a recently proposed method for training deep neural networks where additional samples are generated during training by convexly combining random pairs of images and their associated labels. While simple to implement, it has shown to be a surprisingly effective meth…
