1. 1. Evaluation of Methods for Sound Source Separation in Audio Recordings Using Machine Learning

   University essay from Linköpings universitet/Kommunikationssystem

   Author : Amanda Gidlöf; [2023]
   Keywords : Sound source separation; signal processing; audio processing; speech enhancement; speaker identification; speech separation; speech processing; speaker separation; single channel; multi channel; cocktail party problem; machine learning; neural network; deep learning; deep neural network; convolutional network; dual-path network; filter-and-sum network; recurrent network; beamforming;

   Abstract : Sound source separation is a popular and active research area, especially with modern machine learning techniques. In this thesis, the focus is on single-channel separation of two speakers into individual streams, and specifically considering the case where two speakers are also accompanied by background noise.

3. 2. A Deep Learning Approach to Brain Tracking of Sound

   University essay from Linköpings universitet/Reglerteknik

   Author : Oscar Hermansson; [2022]
   Keywords : Cocktail party problem; AAD; GANs; CNN; FIR; Stimulus reconstruction; Locus of attention decoding; EEG;

   Abstract : Objectives: Development of accurate auditory attention decoding (AAD) algorithms, capable of identifying the attended sound source from the speech evoked electroencephalography (EEG) responses, could lead to new solutions for hearing impaired listeners: neuro-steered hearing aids. Many of the existing AAD algorithms are either inaccurate or very slow. READ MORE

4. 3. Mapping an Auditory Scene Using Eye Tracking Glasses

   University essay from Linköpings universitet/Reglerteknik

   Author : Alfred Fredriksson; Joakim Wallin; [2020]
   Keywords : Sensor Fusion;

   Abstract : The cocktail party problem introduced in 1953 describes the ability to focus auditory attention in a noisy environment epitomised by a cocktail party. An individual with normal hearing uses several cues to unmask talkers of interest, such cues often lacks for people with hearing loss. READ MORE

5. 4. Domain Adaptation for Attention Steering

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Johanna Wilroth; [2020]
   Keywords : Technology and Engineering;

   Abstract : A major problem in the development of intelligent hearing aids is often referred to as the cocktail party problem. It describes the remarkable ability of the human brain of filter out unwanted sounds in a noisy environment, while focusing on a single talker or conversation. READ MORE

6. 5. Improving Classification of Auditory Attention using Optimized Multitapers and Machine Learning

   University essay from Lunds universitet/Matematisk statistik

   Author : Ante Forsgren; [2020]
   Keywords : Mathematics and Statistics;

   Abstract : The cocktail-party problem relates to the challenge of separating a single sound source from a noisy and crowded background based on the listener’s attention. Earlier work has been done in order to use the relations between the sounds heard and the following brain response to develop a model that can accurately classify which sound an individual listener is listening to.
