Perceptual Quality Loss or Loss of Perceptual Quality?

Danilo de Oliveira, Tal Peer, Maurício do V. M. da Costa +1

Contemporary deep speech enhancement (SE) models are often trained with specific auxiliary terms in the loss function as a way to improve their performance in terms of perceptual m…

Livin' on a Prior: Likelihood Score Approximation for Inverse Problems

Rostislav Makarov, Tal Peer, Danilo de Oliveira +1

Generative models have found great success as data-driven methods of solving inverse problems. Two popular approaches work either by combining a pretrained generative prior with a…

Too Good to Be True: A Study on Modern Automatic Speech Recognition for the Evaluation of Speech Enhancement

Danilo de Oliveira, Tal Peer, Timo Gerkmann

Speech enhancement (SE) systems are typically evaluated using a variety of instrumental metrics. The use of automatic speech recognition (ASR) systems to evaluate SE performance is…

Are These Even Words? Quantifying the Gibberishness of Generative Speech Models

Danilo de Oliveira, Tal Peer, Jonas Rochdi +1

Significant research efforts are currently being dedicated to non-intrusive quality and intelligibility assessment, especially given how it enables curation of large scale datasets…

Enhancing In-the-Wild Speech Emotion Conversion with Resynthesis-based Duration Modeling

Navin Raj Prabhu, Danilo de Oliveira, Nale Lehmann-Willenbrock +1

Speech Emotion Conversion aims to modify the emotion expressed in input speech while preserving lexical content and speaker identity. Recently, generative modeling approaches have…

LipDiffuser: Lip-to-Speech Generation with Conditional Diffusion Models

Julius Richter, Danilo de Oliveira, Tal Peer +1

We present LipDiffuser, a conditional diffusion model for lip-to-speech generation synthesizing natural and intelligible speech directly from silent video recordings. Our approach…

Do We Need EMA for Diffusion-Based Speech Enhancement? Toward a Magnitude-Preserving Network Architecture

Julius Richter, Danilo de Oliveira, Timo Gerkmann

We study diffusion-based speech enhancement using a Schrodinger bridge formulation and extend the EDM2 framework to this setting. We employ time-dependent preconditioning of networ…

Non-intrusive Speech Quality Assessment with Diffusion Models Trained on Clean Speech

Danilo de Oliveira, Julius Richter, Jean-Marie Lemercier +2

Diffusion models have found great success in generating high quality, natural samples of speech, but their potential for density estimation for speech has so far remained largely u…

Investigating Training Objectives for Generative Speech Enhancement

Julius Richter, Danilo de Oliveira, Timo Gerkmann

Generative speech enhancement has recently shown promising advancements in improving speech quality in noisy environments. Multiple diffusion-based frameworks exist, each employing…

The PESQetarian: On the Relevance of Goodhart's Law for Speech Enhancement

Danilo de Oliveira, Simon Welker, Julius Richter +1

To obtain improved speech enhancement models, researchers often focus on increasing performance according to specific instrumental metrics. However, when the same metric is used in…

Distilling HuBERT with LSTMs via Decoupled Knowledge Distillation

Danilo de Oliveira, Timo Gerkmann

Much research effort is being applied to the task of compressing the knowledge of self-supervised models, which are powerful, yet large and memory consuming. In this work, we show…

On the Behavior of Intrusive and Non-intrusive Speech Enhancement Metrics in Predictive and Generative Settings

Danilo de Oliveira, Julius Richter, Jean-Marie Lemercier +2

Since its inception, the field of deep speech enhancement has been dominated by predictive (discriminative) approaches, such as spectral mapping or masking. Recently, however, nove…
