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

    Master-uppsats, Linköpings universitet/Kommunikationssystem

    Författare :Amanda Gidlöf; [2023]
    Nyckelord :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;

    Sammanfattning : 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. Domain Adaptation for Attention Steering

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Johanna Wilroth; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : This paper deconstructs twelve contemporary political speeches from leaders of the Swedish parliament, using Julia Kristeva’s interpretation of the abject. Focusing mainly on Annie Lööf (C) and Jimmie Åkesson (SD), it examines speeches made at Almedalsveckan, spanning the years 2014–2019. LÄS MER

  5. 4. Beamforming and Blind Signal Separation for Far-field Voice Capture using a Microphone Array

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Luke Postema; Johan Davidsson; [2019]
    Nyckelord :Beamforming; Microphone array; Minimum variance distortionless response; delay-and-sum; direction of arrival; blind signal separation; Technology and Engineering;

    Sammanfattning : With the evolving technology of mobile electronics and other forms of communication methods, an increasing demand of speech intelligibility is introduced. In a conference room for example, multiple microphones are placed directly in front of the speaker in order to pick up clean speech. However, several challenges still exist. LÄS MER

  7. 5. Support Vector Machines for Optimizing Speaker Recognition Problems.

    Kandidat-uppsats, KTH/Optimeringslära och systemteori

    Författare :Jennie Falk; Gabriella Hultström; [2012]
    Nyckelord :;

    Sammanfattning : Classi cation of data has many applications, amongst others within the eld of speaker recognition. Speaker recognition is the part of speech processing concerned with the task of automatically identifying or verifying speakers using dierent characteristics of their voices. LÄS MER
