Owner authentication for mobile devices using motion gestures based on multi-owner template update

2015

This paper proposes a template updating method for improving authentication accuracy in behavioral biometric authentication with hand/arm motion gestures for mobile devices. We introduce an extended version of the standard K-Medoids based clustering algorithm called …

ESPnet-ST: All-in-One Speech Translation Toolkit

2020 · arXiv (Cornell University)

We present ESPnet-ST, which is designed for the quick development of speech-to-speech translation systems in a single framework. ESPnet-ST is a new project inside end-to-end speech processing toolkit, ESPnet, which integrates or newly implements automatic …

ESPnet: End-to-End Speech Processing Toolkit

2018 · arXiv (Cornell University)

This paper introduces a new open source platform for end-to-end speech processing named ESPnet. ESPnet mainly focuses on end-to-end automatic speech recognition (ASR), and adopts widely-used dynamic neural network toolkits, Chainer and PyTorch, as a …

A Comparative Study on Transformer vs RNN in Speech Applications

2019 · 2019 IEEE Automatic Speech Recognition and Understanding Workshop (ASRU)

Sequence-to-sequence models have been widely used in end-to-end speech processing, for example, automatic speech recognition (ASR), speech translation (ST), and text-to-speech (TTS). This paper focuses on an emergent sequence-to-sequence model called Transformer, which achieves state-of-the-art …
