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

Interspeech 20212021End-to-end automatic speech recognition systems map a sequence of acoustic features to text. In modern systems, text is encoded to grapheme subwords which are generated by methods designed for text processing tasks and therefore don’t model or take advantage of the statistics of the acoustic features. Here, we present a novel method for generating grapheme subwords that are derived from phoneme sequences

Interspeech 20212021Fine-tuning transformer-based models have shown to outperform other methods for many Natural Language Understanding (NLU) tasks. Recent studies to reduce the size of transformer models have achieved reductions of > 80%, making on-device inference on powerful devices possible. However, other resource-constrained devices, like those enabling voice assistants (VAs), require much further reductions. In this
