Synthetic vocal tracts are gadgets powered by a computer system capable of translating the brain activity into synthesized speech, by decoding the movements of muscles involved in vocalization, using advanced computer programming. New standardized method for the development of synthetic vocal tract is the 3D vocal tract model with the binary conversion. Few of the typical features considered while creating the synthetic vocal tract are fundamental frequency, perturbation measure, jitter and change in pitch. The tissue engineered larynx is the promising development in synthetic vocal tract treatment in case of patients with vocal fold repair and regeneration. The future of this interesting technology lies in using high speed video endoscopy based synthetic vocal cords. The review was done based on the articles obtained from various platforms. This review article elaborates about the principle of synthetic vocal tract. Quality of the article used was assessed using a quality assessment tool and graded as strong, moderate and weak. The aim of this study is to understand the concept of synthetic vocal tract and its significance. Synthetic vocal tract is a recently established biomedical tool that has come as a boon in treating patients with severe disabilities. Speech synthesis is evolving as a viable solution as more research is being carried out on this. To understand the full significance of this crucial technique, more research has to be carried out on this field of biomedical engineering and viable solutions need to be developed, so that this novel technique is fully utilized.
The relation between climatic changes and health is the major concern in the healthcare system; cardiovascular diseases are the leading causes of death worldwide. Both extreme hot and cold temperature can cause deaths associated with cardiovascular diseases. The aim of this study is to analyse the awareness and knowledge on the effect of extreme or high temperature in increased heart-related death rate. A survey with a set of 10 questions was prepared. The questions were administered to 100 participants through google docs by sharing the link. The questionnaire consists of questions related to temperature and heart-related death rate. The study populations were dental students. Majority of the population (i.e.) 91% of the students are aware, and 18% of them aren't aware about the effect of temperature on heart-related deaths. When gender was compared with awareness on extreme or high temperatures in CVD mortality rate, and it was not statistically significant. Hence females were more aware that extreme temperature increases CVD mortality rate than male. Extreme heat and cold temperature have been associated with a higher mortality rate in cardiovascular diseases and conditions like strokes and dysrhythmia. Cardiovascular disease is already the deadliest medical condition and mortality rate related to cardiovascular disorders may triple in extreme heat environments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
