Third International Workshop on Models and Analysis of Vocal Emissions for Biomedical Applications (MAVEBA 2003)
Endotracheal intubation is a method commonly applied nowadays in medicine, particularly in surgical procedures carried out under general anaesthetic. It is however an invasive method which may result in many complications, including mechanical injuries of the larynx. The problem is not of purely medical nature. However from the research point of view the detailed analysis of vocal folds damages is necessary. In the present work the attention is mainly focused on the prospects of application of a dedicated acoustical analysis of the speech signal, based on professional methods of signal processing. In the field considered in the present work the objectives of the signal processing and classification are different from the usual ones (revealing the origins of the deformation and evaluation of the signal deformation level in relation to the standard. The acoustic and phonetic properties of the signal itself are essentially different from the widely known parameters of correct speech.
