This paper describes a modified vocoder-based frequency-lowering system similar to one reported by Posen et al. (1993), with the goal of improving place-of-articulation perception by enhancing the spectral differences of fricative consonants.
Furthermore, articulation and speech perception were found separate but correlated abilities.
The first part of the course focuses on the main areas of phonetics: articulation, acoustics, and perception.
A detailed analysis of the transmission of phonetic features indicates that "voicing" is best preserved whereas "manner of articulation" yields most perception errors.
Metabolic imaging showed, and it is generally agreed, that language elements, for example, meaningful words and sounds distinguishing between them, are cortically stored as distributed neuronal ensembles binding perception, articulation, and semantic information (Barsalou 1999; Pulvermüller 1999, 2005; Fuster 2003; Rizzolatti and Craighero 2004; Feldman 2006; Kiefer et al. 2007).
Other studies could show that speech listening automatically induces changes in articulatory movements, thus providing further arguments for causal functional links between the perception and articulation of speech sounds in the absence of classification tasks (Yuen et al. 2010; D'Ausilio et al. 2014).
Gathered in the cerebellum are the cells that govern voluntary movements and muscular coordination, including those involved in fine manual skills, posture perception, and speech articulation.
Thus, building on previous knowledge on phoneme representation in the brain, we tried to provide a finer characterization of the fronto-temporal language cortex: in fact, we compared modalities of perception, production and articulation imagery within the same pipeline and testing them with a complex vowel model, where all items carry equal complexity.
While enhancing speech perception through visible articulation has been the main focus of SynFace, recent work has been aimed at improving the overall communicative experience through nonarticulatory facial movements.
This means that many studies are exposed to infer the workings of the independent components and subcomponents of sensation, perception, reading, and articulation, each representing independent cognitive functions.
The present study probes perception of place of articulation distinctions among Polish sibilants using an AX discrimination task, and compares results from 13 Polish-speaking and 10 English-speaking subjects.
