      abstract     = {A human respiratory system consists of phonation components
                      that are coupled in a complex manner in order to ensure
                      various vital functions, in particular voice generation.The
                      interdisciplinary nature of the processes controlling sound
                      generation complicates the analysis. Analytical studies are
                      limited and can only be used to characterize the main
                      acoustic sources in connection to various types of fluid
                      motion.Numerical investigations of sound generation require
                      an accurate simulation of the flow field with a proper
                      representation of the respiratory pathways and process
                      conditions in order to get the acoustic source terms.
                      Furthermore, voice formation is closelyrelated to the
                      resonance of acoustic modes in and around the mouth cavity;
                      in order to be able to model this properly, it is essential
                      to identify first the sound sources excited within the vocal
                      tract.To better elucidate this complex process, the
                      fundamental mechanisms in a biofluid flow mimicking such
                      configurations were investigated based on a simplified
                      stenotic pipe using high-resolution DNS and LES.},
