    %X This system aims at reproducing the behaviour of a musician’s lips in a stable and controlled way. Firstly, the study focuses on the characterisation of this determining element (i.e. artificial lips) in order to improve their performance. Secondly, artificial mouth settings are studied to identify their correlation with the tonal response of the system. A minimal configuration has been chosen for this study : a plexiglass mouth cavity connected to an air supply and water-filled lips. It is possible to control the lip stiffness and the cavity air pressure by adjusting the water volume in the lips, the air flow in the cavity, and the distance between the lips and the mouthpiece. The first study pointed out the complexity of the mechanical system composed with the two lips, their high sensibility to the settings, as well as the results dispersion due to initial state of stress and damage. This sensitivity to external factors was confirmed during the second step thanks to the use of an audio descriptor set applied to recordings carried ou during the experiments.
