1. Deep Learning for Speech Enhancement : A Study on WaveNet, GANs and General CNN-RNN ArchitecturesMaster-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
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. New Variants of Nonnegative Matrix Factorization with Application to Speech Coding and Speech EnhancementMaster-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
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
- Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)
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
- Master-uppsats, Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling
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
- Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik
Sammanfattning : This master thesis was completed at Limes Audio in Umeå. Limes Audio are specialized in speech enhancement software which is mostly used in conference phones. Their software is used to reduce noise, echo cancellation as well as reduction of distortion. LÄS MER
