A system for ubiquitous distributed acquisition of voice alteration samples through a mobile application

Dysphonia, caused by irregular vocal folds vibration, is one of the major symptoms of benign laryngeal diseases and other organic and functional pathologies. The paper presents a cloud-based system for remote analysis of vocal samples submitted by patient through his smartphone using a mobile application which acquires, preprocesses and adds metadata. The system provides a first-level information on possible voice alterations and, if necessary, suggests doing an accurate voice control by a specialist.
