DHASP: Differentiable Hearing Aid Speech Processing

no code implementations15 Mar 2021 Zehai Tu, Ning Ma, Jon Barker

In this paper, we explore an alternative approach to finding the optimal fitting by introducing a hearing aid speech processing framework, in which the fitting is optimised in an automated way using an intelligibility objective function based on the HASPI physiological auditory model.
