BACKGROUND phonological disorder. AIM to verify the association between the phonological performance in picture naming and imitation tasks, assessing the occurrence of phonological processes and using the severity indexes of Percentage of Correct Consonants and Phonological Density Index. METHOD participants of this research were 50 phonologically disordered children, with no history of pri...

This paper presents a constraint model for the interpretation of multilinear representations of speech utterances which can provide important fine-grained information for speech recognition applications. The model uses explicit structural constraints specifying overlap and precedence relations between features in both the phonological and the phonetic domains in order to recognise well-formed s...

Objectives: The purpose of this study was to examine the phonological processing skills between children with delay and disorder compared those typically developing children. This aimed explore whether show general or specific weakness on if can differentiate from disorder. Methods: participants were 27 speech sound disorders (SSDs) 20 Children SSDs consisted 10 17 tasks for involved awareness ...

Cognitive skills are the emergent property of distributed neural networks. The distributed nature of these networks does not necessarily imply a lack of specialization of the individual brain structures involved. However, it remains questionable whether discrete aspects of high-level behavior might be the result of localized brain activity of individual nodes within such networks. The phonologi...

the spreading activation models of mental lexicon's structure have presented the lexicon in multiple layers (semantic- syntactic- phonological). each layer is a network of nodes which are associated by links. the nature of these links is different from layer to layer. the literature for english speakers has shown that in the phonological layer, phonological forms of words have been linked based...

We present a model of unsupervised phonological lexicon discovery—the problem of simultaneously learning phoneme-like and word-like units from acoustic input. Our model builds on earlier models of unsupervised phone-like unit discovery from acoustic data (Lee and Glass, 2012), and unsupervised symbolic lexicon discovery using the Adaptor Grammar framework (Johnson et al., 2006), integrating the...

This paper introduces a formal account of p-structure via a new conception, the p-diagram. It is based on the phonological unit of the syllable, which constitutes the phonological string. On top of this basic entity, prosodic layers are added ‘as needed’ and tied to the respective syllables via vectors. The result is a theory-independent and compact description of the speech signal itself, whic...

Recent years have revealed that certain global attributes of speech rhythm can be quite successfully captured with respect to consonantal and vocalic intervals in spoken texts. One of the problems of this approach lies in complex syllabic structures. Unless we make an a-priori phonological decision, sonorous consonants may contribute to either vocalic or consonantal part of the speech signal in...

The ProSynth speech synthesis project aims to reimplement and extend the YorkTalk all-prosodic synthesis system in an open manner preserving its most appealing theoretical aspects. A significant novel aspect of the architecture of ProSynth is the use of the extensible mark-up language (XML) as a computational formalism for the representation of hierarchical linguistic structures. The facilities...

A recognition system must include structures which accoupt f?r ~he di~feren~ aspects of. possible phonological vanab1hty m the mcommg speech s1gnal. To aid in dealing with variability at the phonological level, a grapheme-toseveral-phoneme strings module, V ARIONO, has been developed at LIMSI. Tests of this system showed the necess1ty of creating a hierarchical structure to order phon<?lo~ica~ ...
