Multi-Channel Transformer Transducer for Speech Recognition

no code implementations30 Aug 2021 Feng-Ju Chang, Martin Radfar, Athanasios Mouchtaris, Maurizio Omologo

In this paper, we present a novel speech recognition model, Multi-Channel Transformer Transducer (MCTT), which features end-to-end multi-channel training, low computation cost, and low latency so that it is suitable for streaming decoding in on-device speech recognition.

Sample Drop Detection for Distant-speech Recognition with Asynchronous Devices Distributed in Space

1 code implementation15 Nov 2019 Tina Raissi, Santiago Pascual, Maurizio Omologo

The candidate time windows are selected from a set of large time intervals, possibly including a sample drop, and by using a preprocessing step.

DiPCo -- Dinner Party Corpus

no code implementations30 Sep 2019 Maarten Van Segbroeck, Ahmed Zaid, Ksenia Kutsenko, Cirenia Huerta, Tinh Nguyen, Xuewen Luo, Björn Hoffmeister, Jan Trmal, Maurizio Omologo, Roland Maas

We present a speech data corpus that simulates a "dinner party" scenario taking place in an everyday home environment.


Automatic context window composition for distant speech recognition

no code implementations26 May 2018 Mirco Ravanelli, Maurizio Omologo

Distant speech recognition is being revolutionized by deep learning, that has contributed to significantly outperform previous HMM-GMM systems.

Improving speech recognition by revising gated recurrent units

1 code implementation29 Sep 2017 Mirco Ravanelli, Philemon Brakel, Maurizio Omologo, Yoshua Bengio

First, we suggest to remove the reset gate in the GRU design, resulting in a more efficient single-gate architecture.

A network of deep neural networks for distant speech recognition

no code implementations23 Mar 2017 Mirco Ravanelli, Philemon Brakel, Maurizio Omologo, Yoshua Bengio

Despite the remarkable progress recently made in distant speech recognition, state-of-the-art technology still suffers from a lack of robustness, especially when adverse acoustic conditions characterized by non-stationary noises and reverberation are met.
