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. Perceptually meaningful time and frequency resolution in applying dialogue enhancement in noisy environments : Dialogue Enhancement research

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : SUSHANTH PATIL; [2023]
   Keywords : Dialogue enhancement; audio signal processing; Fourier transform; time constants; environmental noise analysis; noise compensation; subjective listening test; speech intelligibility; quality of experience; listening effort.; Dialogförbättring; ljudsignalbehandling; Fouriertransform; tid konstanter; miljöbrusanalys; bruskompensation; subjektivt lyssnande test; taluppfattbarhet; upplevelsekvalitet; lyssnaransträngning;

   Abstract : Dialogue Enhancement (DE) is a process used in audio delivery systems to improve the clarity, intelligibility, and overall quality of the spoken dialogue in audio content. It is primarily used when dialogue is masked by music, surrounding noise, or other audio sources. READ MORE

4. 3. Speech Intelligibility in Radio Broadcasts : A Case Study Using Dynamic Range Control and Blind Source Separation

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Martin Linder Nilsson; [2022]
   Keywords : Speech enhancement; speech intelligibility; audibility; dynamic range control; blind source separation; object-based audio; public service.;

   Abstract : Creating the optimal balance between dialogue level and ambient sound is extremely important in media productions. This process is however inherently difficult due to that people’s requirements and preferences are not uniform. READ MORE

5. 4. Episodic memory placebo: first try

   University essay from Lunds universitet/Institutionen för psykologi

   Author : Pietro Rizzo; [2021]
   Keywords : classical conditioning; cognitive placebo; episodic memory; placebo effects; subliminal speech priming; Social Sciences;

   Abstract : Literature shows that it is possible to induce placebo effects through classical conditioning. Literature also offers first evidence of a semantic memory retrieval enhancement effect elicited through a manipulation of expectancy, which may or may not fit the name of semantic memory retrieval placebo.

6. 5. Detection of Human Emotion from Noise Speech

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
   Keywords : Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

   Abstract : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. READ MORE
