  1. 1. Deep Learning for Speech Enhancement : A Study on WaveNet, GANs and General CNN-RNN Architectures

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Oscar Xing Luo; [2019]
    Nyckelord :;

    Sammanfattning : Clarity and intelligiblity are important aspects of speech, especially in a time of misinformation and mistrust. The breakthrough in generative models for audio files has brought massive improvements for speech enhancement. LÄS MER

  2. 2. New Variants of Nonnegative Matrix Factorization with Application to Speech Coding and Speech Enhancement

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Pedro Jafeth Villasana Tinajero; [2019]
    Nyckelord :;

    Sammanfattning : In this thesis, new variants of nonnegative matrix factorization (NMF) based ona convolutional data model, -divergence and sparsication are developed andanalyzed. These NMF variants are collectively referred to as -CNMF. Commonsparsication techniques such as L1-norm minimization and elastic net arediscussed and a new regularizer is proposed. LÄS MER

  3. 3. Single Channel Spectrum-based Speech Enhancement Using Neural Networks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Filip Wen-Fwu Tsai; [2019]
    Nyckelord :;

    Sammanfattning : The ability to communicate is fundamental to form a relationship, and it is anecessity for a well-functioning society. Since a major part of our daily communicationtakes place orally, the ability to perceive speech is important. LÄS MER

  4. 4. Low Complexity Beamformer structures for application in Hearing Aids

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Författare :Eleni Koutrouli; [2018]
    Nyckelord :hearing aids; beamformers; MVDR algorithm; microphone arrays;

    Sammanfattning : Background noise is particularly damaging to speech intelligibility for people with hearing loss. The problem of reducing noise in hearing aids is one of great importance and great difficulty. Over the years, many solutions and different algorithms have been implemented in order to provide the optimal solution to the problem. LÄS MER
