Single-Microphone Speech Dereverberation: Modulation Domain Processing and Quality Assessment
… the past few years. Although multiple channel dereverberation methods provide some improvements in speech quality/ intelligibility, single-channel dereverberation remains an open challenge. Two types of advanced single-channel dereverberation methods, namely acoustic domain spectral subtraction …

Toward More Intelligible Simultaneous Multi-channel Speech Enhancement and Recognition
… into the multi-channel speech enhancement and dereverberation network further reduces the word error rate (WER) metric for the downstream ASR task.</p>

Multi-modal and deep learning for robust speech recognition
… we explored a speech feature denoising and dereverberation method via deep denoising autoencoders (DDA). The method was evaluated on the CHiME2-WSJ0 corpus and achieved a 16% to 25% absolute improvement in word error rate (WER) compared to the baseline. Third, we developed a method to …

On entropic and compositional sound and its sources
… time and is contrasted with results obtained via dereverberation (i.e. removing the effect of pressure build up due to acoustic reflections). Indirect noise transfer functions are calculated using the acoustic and compositional measurements, and issues pertaining to the methods applied are …

Statistical Model Based Multi-Microphone Speech Processing: Toward Overcoming Mismatch Problem
… purposes, we can have good demixing or dereverberation results. Finally, IBM estimation and ASR are jointly formulated under a GEM framework. Even with the optimal front-end pre-processing, there always exists a mismatched portion with the statistical speech process model which is going …

Example-based audio editing
Traditionally, audio recordings are edited through digital audio workstations (DAWs), which give users access to different tools and parameters through a graphical user interface (GUI) without prior knowledge in coding or signal processing. The complexity of working with DAWs and the undeniable …
