Frequency warping for VTLN and speaker adaptation by linear transformation of standard MFCC

TLDR
The performance of the new LT was comparable to that of regular VTLN implemented by warping the Mel filterbank, when the MLS criterion was used for FW estimation, and it is shown that the approximations involved do not lead to any performance degradation.

Acoustic Analysis for Automatic Speech Recognition

TL;DR: While the main focus in ASR is to obtain spectral envelope measures, human speech communication efficiently exploits the manipulation of one's vocal-cord vibration rate, and so F0 extraction and its integration into ASR are also reviewed.

Addressing pitch Mismatch for Children's Automatic Speech Recognition

Shweta Ghai
TL;DR: In this paper, the effect of variations in each of these acoustic correlates across speech signals is studied on Mel frequency cepstral coefficient (MFCC) features and ASR models.

Golden speaker builder – An interactive tool for pronunciation training

TL;DR: Golden Speaker Builder is presented, a tool that allows learners to generate a personalized “golden-speaker” voice: one that mirrors their own voice but with a native accent.

A study of acoustic-to-articulatory inversion of speech by analysis-by-synthesis using chain matrices and the Maeda articulatory model

TL;DR: A quantitative study of acoustic-to-articulatory inversion for vowel speech sounds by analysis-by-synthesis using the Maeda articulatory model is performed and good agreement between estimated midsagittal VT outlines and measured XRMB tongue pellet positions was achieved.
Journal ArticleDOI

Vocal Tract Length Normalization for Statistical Parametric Speech Synthesis

TL;DR: This paper presents an efficient implementation of VTLN using expectation maximization and addresses the key challenges faced in implementing V TLN for synthesis.

Comparison of parametric representations for monosyllabic word recognition in continuously spoken sentences

TL;DR: In this article, several parametric representations of the acoustic signal were compared with regard to word recognition performance in a syllable-oriented continuous speech recognition system, and the emphasis was on the ability to retain phonetically significant acoustic information in the face of syntactic and duration variations.

Maximum likelihood linear regression for speaker adaptation of continuous density hidden Markov models

TL;DR: An important feature of the method is that arbitrary adaptation data can be used—no special enrolment sentences are needed and that as more data is used the adaptation performance improves.

Maximum likelihood linear transformations for HMM-based speech recognition

TL;DR: The paper compares the two possible forms of model-based transforms: unconstrained, where any combination of mean and variance transform may be used, and constrained, which requires the variance transform to have the same form as the mean transform.

Minimum classification error rate methods for speech recognition

TL;DR: The issue of speech recognizer training from a broad perspective with root in the classical Bayes decision theory is discussed, and the superiority of the minimum classification error (MCE) method over the distribution estimation method is shown by providing the results of several key speech recognition experiments.
