Abstract
Voice analysis is done as part of phoniatric examination, which provides a scheme of the voice field, the so called phonetogram. The application RealVoiceLab developed by the Musical Acoustics Research Centre at HAMU (Academy of Performing Arts in Prague) in Matlab environment makes it possible to create a phonetogram in real time, and to perform subsequent analyses such as the voice field area, position of most frequent representations, and voice manifestation statistics after the recording is completed.
