Live Iterative Ptychography with projection-based algorithms
Simon Welker, Tal Peer, Henry N. Chapman +1
In this work, we demonstrate that the ptychographic phase problem can be solved in a live fashion during scanning, while data is still being collected. We propose a generally appli…
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…
A Flexible Online Framework for Projection-Based STFT Phase Retrieval
Tal Peer, Simon Welker, Johannes Kolhoff +1
Several recent contributions in the field of iterative STFT phase retrieval have demonstrated that the performance of the classical Griffin-Lim method can be considerably improved…
Single and Few-step Diffusion for Generative Speech Enhancement
Bunlong Lay, Jean-Marie Lemercier, Julius Richter +1
Diffusion models have shown promising results in speech enhancement, using a task-adapted diffusion process for the conditional generation of clean speech given a noisy mixture. Ho…
EMOCONV-DIFF: Diffusion-based Speech Emotion Conversion for Non-parallel and In-the-wild Data
Navin Raj Prabhu, Bunlong Lay, Simon Welker +2
Speech emotion conversion is the task of converting the expressed emotion of a spoken utterance to a target emotion while preserving the lexical content and speaker identity. While…
Diffusion Posterior Sampling for Informed Single-Channel Dereverberation
Jean-Marie Lemercier, Simon Welker, Timo Gerkmann
We present in this paper an informed single-channel dereverberation method based on conditional generation with diffusion models. With knowledge of the room impulse response, the a…
