چکیده

A new approach is described which estimates vocal tract shape sequences for speech consisting of voiceless speech and periods of silence as well as voiced speech. This method, based on the use of articulatory codebooks, has proved successful in identifying the place position of stops and fricatives. Secondly, we focus on voiced speech in particular. A fast analysisby-synthesis scheme, which gives continuously-valued area estimates, has been developed. Savings in computation of 50:1 have been achieved by using an MLP to perform the synthesis in this method. The technique also allows a more complex dynamic model to be used.

Deriving articulatory representations of speech

Compared with the usual acoustic representations, articulatory models ooer potential beneets in giving a compact, slowly changing representation, having a closer relationship with the phonetic domain and allowing a straightforward treatment of coarticulation and transitional eeects. A long-standing diiculty preventing the realisation of these beneets is the estimation of appropriate parameters ...

Pseudo-articulatory representations: promise, progress and problems

Pseudo-Articulatory Representations (PARs) have been proposed and discussed in relation to speech processing with results reported for both synthesis and recognition. PARs are derived from linguistic specifications of articulatory activity which are both abstract and idealized. The abstractions and idealizations permit the linguistic generality to be distinguished from the articulatory reality;...

Articulatory synthesis from x-rays and inversion for an adaptive speech robot

This paper describes a speech robotic approach to articulatory synthesis. An anthropomorphic speech robot has been built, based on a real reference subject’s data. This speech robot, called the Articulotron, has a set of relevant degrees of freedom for speech articulators, jaw, tongue, lips, and larynx. The associated articulatory model has been elaborated from cineradiographic midsagittal prof...

Parameterization of articulatory pattern in speakers with ALS

A combination of parallel factor analysis (PARAFAC) and principal component analysis (PCA) was used to parameterize the articulatory pattern of tongue, jaw and lip movements in 8 English vowels produced by 7 subjects with amyotrophic lateral sclerosis (ALS). A two-factor PARAFAC model derived an overall articulatory pattern represented by two basic modes dominated by tongue raising and advancem...

On the Nature of Data-driven Primitive Representations of Speech Articulation

A long standing view in speech production research posits that articulatory representations are low dimensional. Conceptual and computational models have been built based on this view. In this work we explore the nature of low dimensional representations derived directly from articulatory signals based on sparsity constraints. Specifically, we present a method to examine how well derived repres...
