Universal Paralinguistic Speech Representations Using Self-Supervised Conformers

no code implementations9 Oct 2021 Joel Shor, Aren Jansen, Wei Han, Daniel Park, Yu Zhang

Many speech applications require understanding aspects beyond the words being spoken, such as recognizing emotion, detecting whether the speaker is wearing a mask, or distinguishing real from synthetic speech.

Attention Bottlenecks for Multimodal Fusion

no code implementations NeurIPS 2021 Arsha Nagrani, Shan Yang, Anurag Arnab, Aren Jansen, Cordelia Schmid, Chen Sun

Humans perceive the world by concurrently processing and fusing high-dimensional inputs from multiple modalities such as vision and audio.

Sparse, Efficient, and Semantic Mixture Invariant Training: Taming In-the-Wild Unsupervised Sound Separation

no code implementations1 Jun 2021 Scott Wisdom, Aren Jansen, Ron J. Weiss, Hakan Erdogan, John R. Hershey

The best performance is achieved using larger numbers of output sources, enabled by our efficient MixIT loss, combined with sparsity losses to prevent over-separation.

Self-Supervised Learning from Automatically Separated Sound Scenes

1 code implementation5 May 2021 Eduardo Fonseca, Aren Jansen, Daniel P. W. Ellis, Scott Wisdom, Marco Tagliasacchi, John R. Hershey, Manoj Plakal, Shawn Hershey, R. Channing Moore, Xavier Serra

Real-world sound scenes consist of time-varying collections of sound sources, each generating characteristic sound events that are mixed together in audio recordings.

Into the Wild with AudioScope: Unsupervised Audio-Visual Separation of On-Screen Sounds

no code implementations ICLR 2021 Efthymios Tzinis, Scott Wisdom, Aren Jansen, Shawn Hershey, Tal Remez, Daniel P. W. Ellis, John R. Hershey

For evaluation and semi-supervised experiments, we collected human labels for presence of on-screen and off-screen sounds on a small subset of clips.

Towards Learning a Universal Non-Semantic Representation of Speech

1 code implementation25 Feb 2020 Joel Shor, Aren Jansen, Ronnie Maor, Oran Lang, Omry Tuval, Felix de Chaumont Quitry, Marco Tagliasacchi, Ira Shavitt, Dotan Emanuel, Yinnon Haviv

The ultimate goal of transfer learning is to reduce labeled data requirements by exploiting a pre-existing embedding model trained for different datasets or tasks.

Improving Universal Sound Separation Using Sound Classification

no code implementations18 Nov 2019 Efthymios Tzinis, Scott Wisdom, John R. Hershey, Aren Jansen, Daniel P. W. Ellis

Deep learning approaches have recently achieved impressive performance on both audio source separation and sound classification.

Unsupervised Learning of Semantic Audio Representations

no code implementations6 Nov 2017 Aren Jansen, Manoj Plakal, Ratheet Pandya, Daniel P. W. Ellis, Shawn Hershey, Jiayang Liu, R. Channing Moore, Rif A. Saurous

Even in the absence of any explicit semantic annotation, vast collections of audio recordings provide valuable information for learning the categorical structure of sounds.

Evaluating Low-Level Speech Features Against Human Perceptual Data

no code implementations TACL 2017 Caitlin Richter, Naomi H. Feldman, Harini Salgado, Aren Jansen

We introduce a method for measuring the correspondence between low-level speech features and human perception, using a cognitive model of speech perception implemented directly on speech recordings.

Automatic Speech Recognition Representation Learning

A segmental framework for fully-unsupervised large-vocabulary speech recognition

5 code implementations22 Jun 2016 Herman Kamper, Aren Jansen, Sharon Goldwater

We also show that the discovered clusters can be made less speaker- and gender-specific by using an unsupervised autoencoder-like feature extractor to learn better frame-level features (prior to embedding).

Unsupervised word segmentation and lexicon discovery using acoustic word embeddings

no code implementations9 Mar 2016 Herman Kamper, Aren Jansen, Sharon Goldwater

In settings where only unlabelled speech data is available, speech technology needs to be developed without transcriptions, pronunciation dictionaries, or language modelling text.

Scalable Out-of-Sample Extension of Graph Embeddings Using Deep Neural Networks

no code implementations18 Aug 2015 Aren Jansen, Gregory Sell, Vince Lyzinski

Several popular graph embedding techniques for representation learning and dimensionality reduction rely on performing computationally expensive eigendecompositions to derive a nonlinear transformation of the input data space.

Bridging the gap between speech technology and natural language processing: an evaluation toolbox for term discovery systems

no code implementations LREC 2014 Bogdan Ludusan, Maarten Versteegh, Aren Jansen, Guillaume Gravier, Xuan-Nga Cao, Mark Johnson, Emmanuel Dupoux

The unsupervised discovery of linguistic terms from either continuous phoneme transcriptions or from raw speech has seen an increasing interest in the past years both from a theoretical and a practical standpoint.
