Envelope Based Time-Frequency Mask for Noise Reduction in Cochlear Implants

EasyChair Preprint 9063

6 pagesDate: October 24, 2022

Abstract

This work presents a time-frequency mask for noise reduction  in cochlear implants. The attenuation function proposal is thought from the minimization of the mean square error between the speech envelopes average and your estimative, consideration computational complexity restrictions. The performance of the proposed method was evaluated through two intelligibility criteria, assuming speech aditived contamination by the babble noise in different SNRs. The results indicate that a proposed mask offers greater intelligibility to the user, compared to the Wiener and Wiener masks, both used in the literature.

Keyphrases: Implante coclear, máscara tempo-frequência, processamento da fala, redução de ruído
