Abstract:
During voiced speech, the larynx provides quasi-periodic acoustic excitation of the vocal tract. In most electrolarynxes, mechanical vibrations are produced by a linear electromechanical actuator, the armature of which percusses against a metal or plastic plate at a frequency within the range of glottal excitation. In this paper, a phonological analysis of a section of results from an online perceptual intelligibility test was performed which compared speech produced using a novel hands-free electrolarynx and a commercially available electrolarynx. A portion of the test consisted of a closed-set format containing a selection of four sets of four random CVC audio samples (recorded by two speakers - 1 male, 1 female - using the Servox™ and the hands-free pager motor design). Each survey participant was requested to listen to every recording and then choose the word they thought most closely resembled the recording in which they heard. The phenomenon referred to as Irish-English, as do...

Abstract:
<p>Cardiovascular Disease is the number one cause of death in the world, with a mortality rate, globally of 35.1% representing 17.6 million lives lost annually. The majority of these deaths are related to vascular diseases, such as atherosclerotic plaques, which can obstruct blood flow perfusion of organs and tissue causing serious injuries or even death. In the heart, in order to prevent heart failure, blood flow to the tissue must be restored as quickly as possible, ideally via minimally invasive interventions such as stenting or other types of angioplasty as the gold standard. However, this is not always suitable, thus, blood vessel bypass grafts may be required. Tissue-engineered vascular grafts has being aimed as a product that has the capacity to be repopulated with the patient’s own cells to reduce immunogenicity and increase graft patency. A particular importance of tissue-engineered vascular grafts using degradable biopolymers is for clinical paediatric cardiothoracic...
