Voice is the basic interpersonal communication modality and is of particular importance in such professions as teacher, journalist or conference center employee. Early diagnosis of occupational voice disorders is becoming one of the health priorities. Current international standards emphasize the need for comprehensive voice assessment in phoniatric examinations. In recent years, techniques for recording laryngoscopic images have been developed, including the sequence of images of vocal folds vibrations. Effective methods of computer analysis of such images are being developed. These techniques contribute to the objectification of phoniatric diagnostics.
