This paper presents the implementation of a dsp based acquisition and elaboration system for voice pathologies early identification. The proposed system performs real-time spectro-acoustic analysis of acquired voice samples and gives a visual feedback to alert about "potential" presence of anomalies in vocal robes. The prototype can also be used for rehabilitation purpose after medical treatment or surgery.
