  1. 1. EEG-Based Speech Decoding Using a Machine Learning Pipeline

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Julia Önerud; [2023]
    Nyckelord :EEG; EEG-Decoding; Speech-like; Neuro; Neurotech; Machine-learning; SVM; Feature Extraction; Feature Selection; Mentalab; Inner Speech; OVR; Baseline-Correction; State-of-the-art; State-of-the-art Accuracy; Directions; Emotions;

    Sammanfattning : his project aims to find a method that will help fill the information gaps in electroencephalography (EEG) brain-computer interfaces (BCI) research, by creating a pipeline method that allows for quicker research iterations than current state-of-the-art methods. The pipeline method is a multi-step processstarting from the recording EEG data from a subject performing a thought paradigm action, continuing with processing and decoding of the data, and ending with visualization and analysis the decoded results.

  3. 2. CLASSIFYING ANXIETY BASED ON A VOICERECORDING USING LEARNING ALGORITHMS

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Oscar Sherlock; Olle Rönnbäck; [2022]
    Nyckelord :ANN; CNN; Machine learning; Deep learning; ML; DL; Voice recognition; Anxiety;

    Sammanfattning : Anxiety is becoming more and more common, seeking help to evaluate your anxiety canfirst of all take a long time, secondly, many of the tests are self-report assessments that could cause incorrect results. It has been shown there are several voice characteristics that are affected in people with anxiety. LÄS MER

  4. 3. Voice Feature Extraction Using Siamese Neural Networks for Detecting Impersonators

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Marlon Almström; Thi Thu Hòa Trân; [2022]
    Nyckelord :deep learning; voice impersonation; audio feature extraction; siamese neural networks; Mathematics and Statistics;

    Sammanfattning : Voice impersonation is a technique that has often been used by criminals whose goal is to avoid being identified while committing a crime. There are, however, other interesting cases where the police confronts a suspect with an incriminating recording, and the suspect would deny being the true speaker in that recording, and claim that it belonged to an expert impersonator.

  5. 4. Voice Biometrics Exploring The Boundaries Of Speaker Verification

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Oscar Johansson; [2022]
    Nyckelord :;

    Sammanfattning : Recent advancements in computational power, datasets and models have resulted in significant performanceincreases across various speech and speaker recognition models. This work investigates the capabilities ofusing voice as a biometric tool, namely what is referred to as speaker verification. LÄS MER

  7. 5. Speaker Recognition using Biology-Inspired Feature Extraction

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

    Författare :Edvin Andersson; [2021]
    Nyckelord :Artificial Intelligence; AI; Machine Learning; Speaker Recognition; Technology and Engineering;

    Sammanfattning : Distinguishing between people's voices is something the human brain does naturally, using only frequencies picked up by the inner ear. The field of speaker recognition is concerned with making machines do the same thing using digitally sampled speech and data processing. LÄS MER
