Relative Acoustic Features for Distance Estimation in Smart-Homes
Francesco Nespoli, Daniel Barreda, Patrick A. Naylor
Any audio recording encapsulates the unique fingerprint of the associated acoustic environment, namely the background noise and reverberation. Considering the scenario of a room eq…
Binaural Speech Enhancement Using STOI-Optimal Masks
Vikas Tokala, Mike Brookes, Patrick A. Naylor
STOI-optimal masking has been previously proposed and developed for single-channel speech enhancement. In this paper, we consider the extension to the task of binaural speech enhan…
Spatial Processing Front-End For Distant ASR Exploiting Self-Attention Channel Combinator
Dushyant Sharma, Rong Gong, James Fosburgh +3
We present a novel multi-channel front-end based on channel shortening with theWeighted Prediction Error (WPE) method followed by a fixed MVDR beamformer used in combination with a…
Time-Frequency Analysis and Parameterisation of Knee Sounds for Non-invasive Detection of Osteoarthritis
Costas Yiallourides, Patrick A. Naylor
Objective: In this work the potential of non-invasive detection of knee osteoarthritis is investigated using the sounds generated by the knee joint during walking. Methods: The inf…
Detection of Glottal Closure Instants from Speech Signals: a Quantitative Review
Thomas Drugman, Mark Thomas, Jon Gudnason +2
The pseudo-periodicity of voiced speech can be exploited in several speech processing applications. This requires however that the precise locations of the Glottal Closure Instants…
The LOCATA Challenge: Acoustic Source Localization and Tracking
Christine Evers, Heinrich Loellmann, Heinrich Mellmann +4
The ability to localize and track acoustic events is a fundamental prerequisite for equipping machines with the ability to be aware of and engage with humans in their surrounding e…
