Cerebral Dominancy Towards Various Sounds in Stutterers

For Stutterers

Morphological brain differences between adult stutterers and non-stutterers

BACKGROUND The neurophysiological and neuroanatomical foundations of persistent developmental stuttering (PDS) are still a matter of dispute. A main argument is that stutterers show atypical anatomical asymmetries of speech-relevant brain areas, which possibly affect speech fluency. The major aim of this study was to determine whether adults with PDS have anomalous anatomy in cortical speech-la...

The production of real and non-words in adult stutterers and non-stutterers: an acoustic study

Dual-route models of speech production suggest that highfrequency forms are encoded in different ways from lowfrequency and novel forms [7, 15, 16]. There is some evidence to suggest that lexical status may have some influence on stuttering behaviour, with higher incidences of stuttering being observed for low frequency words [4, 9]. This paper reports on a study, which investigated the product...

Eye movements of stutterers.

As a consequence of recent inquiries into the brainstem activity of stutterers, saccades and pursuit were evaluated in stutterers and their matched normals while silent and talking. No ocular motor instabilities or aberrations caused by speech were found. Saccadic latencies and gains for the stutterers were normal, but peak velocities were higher and durations were shorter. This finding is cons...

Towards Timbre Recognition of Percussive Sounds

The development of computer algorithms for music instrument identification and parameter extraction in digital audio signals is an active research field. A musician can listen to music and instantly identify different instruments and the timbres produced by various playing techniques. Creating software to allow computers to do the same is much more challenging. This project will use digital sig...
