Challenges and Opportunities in Multi-device Speech Processing

no code implementations27 Jun 2022 Gregory Ciccarelli, Jarred Barber, Arun Nair, Israel Cohen, Tao Zhang

We review current solutions and technical challenges for automatic speech recognition, keyword spotting, device arbitration, speech enhancement, and source localization in multidevice home environments to provide context for the INTERSPEECH 2022 special session, "Challenges and opportunities for signal processing and machine learning for multiple smart devices".

Convolutional Sparse Coding Fast Approximation with Application to Seismic Reflectivity Estimation

no code implementations29 Jun 2021 Deborah Pereg, Israel Cohen, Anthony A. Vassiliou

In sparse coding, we attempt to extract features of input vectors, assuming that the data is inherently structured as a sparse superposition of basic building blocks.

Deep Residual Echo Suppression with A Tunable Tradeoff Between Signal Distortion and Echo Suppression

no code implementations25 Jun 2021 Amir Ivry, Israel Cohen, Baruch Berdugo

In this paper, we propose a residual echo suppression method using a UNet neural network that directly maps the outputs of a linear acoustic echo canceler to the desired signal in the spectral domain.

Voice Activity Detection for Transient Noisy Environment Based on Diffusion Nets

no code implementations25 Jun 2021 Amir Ivry, Baruch Berdugo, Israel Cohen

A deep neural network, which is trained to separate speech from non-speech frames, is obtained by concatenating the decoder to the encoder, resembling the known Diffusion nets architecture.

Nonlinear Acoustic Echo Cancellation with Deep Learning

no code implementations25 Jun 2021 Amir Ivry, Israel Cohen, Baruch Berdugo

Second, the network is succeeded by a standard adaptive linear filter that constantly tracks the echo path between the loudspeaker output and the microphone.

Evaluation of Deep-Learning-Based Voice Activity Detectors and Room Impulse Response Models in Reverberant Environments

no code implementations25 Jun 2021 Amir Ivry, Israel Cohen, Baruch Berdugo

To mitigate this mismatch between training data and real data, we simulate an augmented training set that contains nearly five million utterances.

Data-Driven Tree Transforms and Metrics

1 code implementation18 Aug 2017 Gal Mishne, Ronen Talmon, Israel Cohen, Ronald R. Coifman, Yuval Kluger

Often the data is such that the observations do not reside on a regular grid, and the given order of the features is arbitrary and does not convey a notion of locality.

Kernel-based Sensor Fusion with Application to Audio-Visual Voice Activity Detection

no code implementations11 Apr 2016 David Dov, Ronen Talmon, Israel Cohen

In this paper, we address the problem of multiple view data fusion in the presence of noise and interferences.

Diffusion Nets

no code implementations25 Jun 2015 Gal Mishne, Uri Shaham, Alexander Cloninger, Israel Cohen

In this paper, we propose a manifold learning algorithm based on deep learning to create an encoder, which maps a high-dimensional dataset and its low-dimensional embedding, and a decoder, which takes the embedded data back to the high-dimensional space.
