Modelling the uncertainty in recovering articulation from acoustics

Modelling the uncertainty in recovering articulation from acoustics

This paper presents an experimental comparison of the performance of the multilayer perceptron (MLP) with that of the mixture density network (MDN) for an acoustic-to-articulatory mapping task. A corpus of acoustic-articulatory data recorded by electromagnetic articulography (EMA) for a single speaker was used as training and test data for this purpose. In theory, the MDN is able to provide a r...

From Acoustics to Articulation

The focus of this thesis is the relationship between the articulation of speech and the acoustics of produced speech. There are several problems that are encountered in understanding this relationship, given the non-linearity, variance and non-uniqueness in the mapping, as well as the differences that exist in the size and shape of the articulators, and consequently the acoustics, for different...

Acoustics and Articulation of Spanish /d/ Spirantization

Recent acoustic research has challenged the traditional understanding of the spirantization of Spanish /b d g/. We compare acoustic and EPG results on the realization of /d/ in different contexts. Whereas we largely confirm recent observations regarding the postfricative context, we also show that after nasals and laterals the intensity curve associated with the voiced obstruent /d/ does not of...

Variability and Constancy in the Articulation and Acoustics of

Variability in English vowels is comparable in articulation and acoustics.

The nature of the links between speech production and perception has been the subject of longstanding debate. The present study investigated the articulatory parameter of tongue height and the acoustic F1-F0 difference for the phonological distinction of vowel height in American English front vowels. Multiple repetitions of /i, ɪ, e, ε, æ/ in [(h)Vd] sequences were recorded in seven adult speak...
