Speech-dependent data augmentation for own voice reconstruction with hearable microphones in noisy environments

Eurasip Journal on Audio, Speech, and Music Processing
Hearable devices, equipped with one or more microphones, can be used to capture the user’s own voice in noisy environments. In such environments, an own voice reconstruction (OVR) system is needed to enhance the quality and intelligibility of the ...
