Variational Bayesian estimation and clustering for speech recognition

S Watanabe, Y Minami, A Nakamura… - IEEE Transactions on …, 2004‏ - ieeexplore.ieee.org
In this paper, we propose variational Bayesian estimation and clustering for speech
recognition (VBEC), which is based on the variational Bayesian (VB) approach. VBEC is a …

A parsimonious tour of bayesian model uncertainty

PA Mattei - arxiv preprint arxiv:1902.05539, 2019‏ - arxiv.org
Modern statistical software and machine learning libraries are enabling semi-automated

Simultaneous feature and model selection for continuous hidden Markov models

H Zhu, Z He, H Leung - IEEE Signal Processing Letters, 2012‏ - ieeexplore.ieee.org
In this letter, we propose a novel approach of simultaneous feature and model selection for
continuous hidden Markov model (CHMM). In our method, a set of real valued quantities …

Bayesian adaptive inference and adaptive training

K Yu, MJF Gales - IEEE transactions on audio, speech, and …, 2007‏ - ieeexplore.ieee.org
Large-vocabulary speech recognition systems are often built using found data, such as
broadcast news. In contrast to carefully collected data, found data normally contains multiple …

[PDF][PDF] Variational Bayesian speaker clustering

F Valente, C Wellekens - ODYSSEY04-The Speaker and Language …, 2004‏ - Citeseer
In this paper we explore the use of Variational Bayesian (VB) learning in unsupervised
speaker clustering. VB learning is a relatively new learning technique that has the capacity …

Joint speech enhancement and speaker identification using approximate Bayesian inference

C wa Maina, JML Walsh - IEEE transactions on audio, speech …, 2010‏ - ieeexplore.ieee.org
We present a variational Bayesian algorithm for joint speech enhancement and speaker
identification that makes use of speaker dependent speech priors. Our work is built on the …

[PDF][PDF] Variational Bayesian GMM for speech recognition.

F Valente, C Wellekens - INTERSPEECH, 2003‏ - isca-archive.org
In this paper, we explore the potentialities of Variational Bayesian (VB) learning for speech
recognition problems. VB methods deal in a more rigorous way with model selection and are …

A new variational Bayesian algorithm with application to human mobility pattern modeling

B Wu, CA McGrory, AN Pettitt - Statistics and Computing, 2012‏ - Springer
A new variational Bayesian (VB) algorithm, split and eliminate VB (SEVB), for modeling data
via a Gaussian mixture model (GMM) is developed. This new algorithm makes use of …

Structural Bayesian linear regression for hidden Markov models

S Watanabe, A Nakamura, BH Juang - Journal of Signal Processing …, 2014‏ - Springer
Abstract Linear regression for Hidden Markov Model (HMM) parameters is widely used for
the adaptive training of time series pattern analysis especially for speech processing. The …

[PDF][PDF] Kernel methods for text-independent speaker verification

C Longworth - 2010‏ - mi.eng.cam.ac.uk
In recent years, systems based on support vector machines (SVMs) have become standard
for speaker verification (SV) tasks. An important aspect of these systems is the dynamic …
