Densely Connected Networks with Multiple Features for Classifying Sound Signals with Reverberation
Sensors, 2023 In indoor environments, reverberation can distort the signalseceived by active noise cancelation devices, posing a challenge to sound classification. Therefore, we combined three speech spectral features based on different frequency scales into a densely

Noise-robust blind reverberation time estimation using noise-aware time-frequency masking [PDF]
arXiv, 2021 The reverberation time is one of the most important parameters used to characterize the acoustic property of an enclosure. In real-world scenarios, it is much more convenient to estimate the reverberation time blindly from recorded speech compared to the traditional acoustic measurement techniques using professional measurement instruments.

An Evaluation of Three-Stage Voice Conversion Framework for Noisy and Reverberant Conditions [PDF]
arXiv, 2022 This paper presents a new voice conversion (VC) framework capable of dealing with both additive noise and reverberation, and its performance evaluation. There have been studied some VC researches focusing on real-world circumstances where speech data are interfered with background noise and reverberation. To deal with more practical conditions where no
