Interspeech 20212021Comprehending the overall intent of an utterance helps a listener recognize the individual words spoken. Inspired by this fact, we perform a novel study of the impact of explicitly incorporating intent representations as additional information to improve a recurrent neural network-transducer (RNN-T) based automatic speech recognition (ASR) system. An audio-to-intent (A2I) model encodes the intent of the

Interspeech 20212021We introduce Amortized Neural Networks (AmNets), a compute cost- and latency-aware network architecture particularly well-suited for sequence modeling tasks. We apply AmNets to the Recurrent Neural Network Transducer (RNN-T) to reduce compute cost and latency for an automatic speech recognition (ASR) task. The AmNets RNN-T architecture enables the network to dynamically switch between encoder branches on

Interspeech 20212021By implicitly recognizing a user based on his/her speech input, speaker identification enables many downstream applications, such as personalized system behavior and expedited shopping checkouts. Based on whether the speech content is constrained or not, both text-dependent (TD) and text-independent (TI) speaker recognition models may be used. We wish to combine the advantages of both types of models through

Interspeech 20212021The success of modern deep learning systems is built on two cornerstones, massive amount of annotated training data and advanced computational infrastructure to support large-scale computation. In recent years, the model size of state-of-the-art deep learning systems has rapidly increased and sometimes reached to billions of parameters. Herein we take a close look into this phenomenon and present an empirical

SIGIR 2021 International Workshop on Causality in Search and Recommendation2021We propose a novel method to estimate metrics for a ranking policy, based on behavioral signal data (e.g. clicks or viewing of video contents) generated by a second different policy. Building on [1], we prove the counterfactual estimator is unbiased, and discuss its low-variance property. The estimator can be used to evaluate ranking model performance offline, to validate and selection positional bias models
