Voice Parameter Analysis for the disease detection
نویسندگان
چکیده
The analysis of the human voice has arisen as an important area of study for its various applications in medical as well as engineering sciences. Voice analysis basically deals with extraction of some parameters from voice signal for processing of voice in desirable applicability by using suitable techniques. This paper states the certain common medical conditions which affect voice patterns of patients in evidence to leading research studies that had verified the voice alterations as diagnosis symptom in respective medical conditions. As well as, a comparative study of voice analysis techniques will be presented and special emphasis is given to certain prominent biomedical tools that are commercially available and are fundamentally based on voice analysis technology. Recent advancements in the field of voice analysis systems are also given.

متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...

متن کاملEtiologies of Dysphonia in Patients Referred to ENT Clinics Based on videolaryngoscopy
Introduction: Laryngeal dysfunction may be divided into three categories; organic, neurologic and functional disorders. Dysphonia and hoarseness are the most common symptoms and, in some cases, the only signs of laryngeal dysfunction. In differential diagnosis of any type of chronic hoarseness, a neoplastic process must be considered and, thus continuous light video laryngoscopy can provide imp...
