The evaluation of voice quality and the perception of its degradation through various acoustic clues are major concerns for voice professionals involved in the process of vocal rehabilitation. In this context, it is necessary to pay particular attention to the set of indices capable of delivering relevant information to help diagnose and assess the effects of vocal re-education proposed. Therefore, the contribution of experimental phonetics in clinical practice is a proven fact. If the study we propose is part of the evaluation of voice quality, our problem is to develop a system dedicated to the objective characterization of chronic dysphonia of tumor or inflammatory origin. The aim of the telemedicine device that we develop is threefold: diagnosis, treatment and monitoring of disease. For this we proceed initially to the remote recording and archiving of an acoustic speech signal voiced in this case “a” sustained for three seconds. We then apply at the ENT department of the University Hospital of Tlemcen, different algorithms of objective assessment of three parameters in this case the fundamental frequency, jitter and DFT-RD that allow experts to assess the development of chronic dysphonia of tumor or inflammatory origin (larynx cancer, inflammatory polyp of the vocal cords, chronic laryngitis).
