SS-BRPE: Self-Supervised Blind Room Parameter Estimation Using Attention Mechanisms

ICASSP 2025accepted

In recent years, dynamic parameterization of acoustic environments has garnered attention in audio processing. This focus includes room volume and reverberation time (RT<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">60</inf>), which defines local acous…

Attention Is All You Need For Blind Room Volume Estimation

ICASSP 2024accepted

In recent years, dynamic parameterization of acoustic environments has raised increasing attention in the field of audio processing. One of the key parameters that characterize the local room acoustics in isolation from orientation and directivity of sources and receivers is the geometric room volum…

Target Speaker Extraction by Directly Exploiting Contextual Information in the Time-Frequency Domain

ICASSP 2024accepted

In target speaker extraction, many studies rely on the speaker embedding which is obtained from an enrollment of the target speaker and employed as the guidance. However, solely using speaker embedding may not fully utilize the contextual information contained in the enrollment. In this paper, we di…

Autoregressive Parameter Estimation with Dnn-Based Pre-Processing

ICASSP 2020accepted

In this paper, a method for estimating the autoregressive parameters from a signal segment is proposed. The method is based on a deep neural network (DNN) in combination with the classical Levinson-Durbin recursion (LDR). The DNN acts as a pre-processor for the LDR and can be trained on different me…

Sparse HMM-based speech enhancement method for stationary and non-stationary noise environments

ICASSP 2015accepted

We propose a sparse hidden Markov model (HMM)-based single-channel speech enhancement method that models the speech and noise gains accurately in both stationary and nonstationary environments. The objective function is augmented with an lp regularization term resulting in a sparse autoregressive HM…
