| Popis: | cote interne IRCAM: Lopes13a; None / None; National audience; This paper deals with a robotized arti?cial mouth adapted to brass instruments. A technical description of the robotic platform is drawn, including calibrations, initialization processes, and modes of control. An experimental protocol is proposed and the repeatability is checked. Then, experiments are conducted on a trombone for several types of quasi-static controls. Sound descriptors (fundamental frequency, roughness, energy) of measured acoustic signals are estimated and used to build cartographies indexed by the control inputs. An analysis reveals that several stable notes can easily be reached using a basic mapping with respect to these control inputs. However, the histogram of fundamental frequencies shows that input impedance peaks in the high range of the instrument do not correspond to notes that can be played by the arti?cial mouth, contrarily to musicians. It also reveals that some notes are dif?cult to play in the middle range. This exploration suggests some possible improvements of the machine that are ?nally discussed. |
