Flow-chart of data normalisation and analysis. Raw data of 6 distance parameters were measured in each acquired image sequence. For inter-individual comparison. The timeline has been rescaled: The start of phonation was set to 0% the end point to 100%. Additionally, the distance parameters were normalized to start and end point of phonation (left part) as well as to maximum inspiration and expiration (right part). VC stands for vital capacity.
