Newly Designed Audio-Visual Environment for Laryngeal Examination with Real-Time Voice and Acoustic Analysis Displayed on Multiple Monitors under Various Platforms

Abstract

Simultaneous recording of laryngeal image, sound and voice analysis in one movie file has offered a convenient environment for medical examiners. However, it is not always gentle to the examinee or surrounding participants, including medical staff, due to limited audio-visual circumstances. We have developed a newly designed audio-visual environment for laryngeal examination with real-time voice and acoustic analysis displayed on multiple monitors under various platforms using the latest internet technologies: WebRTC and H.264, and Wi-Fi. In this new environment, anyone can watch the laryngeal image simultaneously using iOS (iPod touch, iPhone, iPad) or Android mobile devices at any place in the examination room.
