Sensorimotor integration, the translation between acoustic signals and motoric programs, may constitute a crucial mechanism for speech. During speech perception, the acoustic-motoric translations include the recruitment of cortical areas for the representation of speech articulatory features, such as place of articulation. Selective attention can shape the processing and performance of speech p...

BACKGROUND Articulation disorders in young children are due to defects occurring at a certain stage in sensory and motor development. Some children with functional articulation disorders may also have sensory integration dysfunction (SID). We hypothesized that speech therapy would be less efficacious in children with SID than in those without SID. Hence, the purpose of this study was to compare...

This paper provides our approach to co-articulation for a text-to-audiovisual speech synthesizer (TTAVS), a system for converting the input text to video realistic audio-visual sequence. It is an image-based system modeling the face using a set of images of a human subject. A concatenation of visemes –the corresponding lip shapes for phonemes— can be used for modeling visual speech. However, in...

We present a methodology for articulating and posing meshes, in particular facial meshes, using sketching as input. Our method focuses on the use of two sketched curves, a reference and target curve. Our articulation system uses these curves to deform selected regions of a mesh in order to specify articulation. Likewise, our posing system uses reference and target curves to find an optimal pose...

This paper describes initial experiments with synthesis of visual speech articulation for different emotions, using a newly developed MPEG-4 compatible talking head. The basic problem with combining speech and emotion in a talking head is to handle the interaction between emotional expression and articulation in the orofacial region. Rather than trying to model speech and emotion as two separat...

This paper presents results from a project on phonetic convergence in German spontaneous speech. We used linear mixed models to examine 22 unimodal and 24 multimodal dialogs for articulation rate. We show that speakers’ local articulation rates are influenced by the preceding rates of their interlocutors, and that the direction of this influence (i.e., divergence or convergence) depends on soci...

We investigated effects of legato, staccato and pizzicato articulation styles on the perception of modulated tempos. Seventy-two music majors served as participants. Two solo violin excerpts were chosen with contrasting rhythmic rates and were recorded in all three articulation styles. Examples were presented to listeners in three conditions of tempo modulation: gradual increase, gradual decrea...

This paper examines the effects of elliptical speech (Miller & Nicely, 1955) on the speech perception performance of an adult hearing-impaired listener with a cochlear implant. A group of 20 normal-hearing adult listeners were used for comparison. Two experiments were carried out using sets of normal and anomalous English sentences. Two versions of each set of sentences were constructed. One ve...

Background and Objectives: Investigating the prevalence of speech and language disorders and the contributing factors can help determine the best treatment options suited to the needs of these patients. So far, no comprehensive study has been conducted on screening speech and reading disorders and problems in the structure and function of articulation organs (PSFAOs) in children in Mashhad City...
