1. 1. Instability of a bi-directional TiFGAN in unsupervised speech representation learning

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

   Author : Matthaios Stylianidis; [2021]
   Keywords : ;

   Abstract : A major challenge in the application of machine learning in the speech domain is the unavailability of annotated data. Supervised machine learning techniques are highly dependent on the amount of labelled data and the quality of the labels. READ MORE

3. 2. Automatic Speech Quality Assessment in Unified Communication : A Case Study

   University essay from Linköpings universitet/Programvara och system

   Author : Kevin Larsson Alm; [2019]
   Keywords : speech; voice; communication; qoe; quality of experience; unified communication; uc; speech quality assessment; speech quality; voice calls; gaussian mixture model; gmm; gaussian mixture regression; gmr; mel frequency cepstrum coefficients; mfcc; human feature cepstrum coefficients; hfcc; gammatone frequency cepstral coefficients; gfcc;

   Abstract : Speech as a medium for communication has always been important in its ability to convey our ideas, personality and emotions. It is therefore not strange that Quality of Experience (QoE) becomes central to any business relying on voice communication. READ MORE

4. 3. A performance measurement of a Speaker Verification system based on a variance in data collection for Gaussian Mixture Model and Universal Background Model

   University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

   Author : Zeid Bekli; William Ouda; [2018]
   Keywords : Speaker recognition; Speaker Verification; Speaker authentication; Speaker classification; Gaussian mixture model; Gaussian Mixture Model-Universal Background Model; Biometric System; Equal Error Rate; False Negative Rate; False Positive Rate; Mel Frequency Cepstrum Coefficients;

   Abstract : Voice recognition has become a more focused and researched field in the last century,and new techniques to identify speech has been introduced. A part of voice recognition isspeaker verification which is divided into Front-end and Back-end. READ MORE

5. 4. Musical Instrument Categorization using Spectral- and Cepstral Analysis

   University essay from Lunds universitet/Matematisk statistik

   Author : Jakob Florén; Joel Torby; [2016]
   Keywords : Mathematics and Statistics;

   Abstract : This thesis suggests and tests two methods for categorizing instruments in a musical signal. The first method involves spectral analysis and the magnitude spectrum, analysing the structure of pitches and overtones and how the amplitude of those changes over time. READ MORE

6. 5. Research and simulation on speech recognition by Matlab

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Linlin Pan; [2014]
   Keywords : speech recognition; algorithm; MFCC; GMM;

   Abstract : With the development of multimedia technology, speech recognition technology has increasingly become a hotspot of research in recent years. It has a wide range of applications, which deals with recognizing the identity of the speakers that can be classified into speech identification and speech verification according to decision modes.
