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

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Julia Önerud; [2023]
    Keywords : 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;

    Abstract : 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.

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

    University essay from Lunds universitet/Matematisk statistik

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

    Abstract : 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.

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

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE
