		<dl>The vocal tract length (VTL) is calculated as: VTL = 100 · 352.95 / (4 · φ) cm. Note that a different formant tracking algorithm is used in Pseudonymize Speech than was used in [2] and the estimated φ values here are used only as scale factors. They should not be interpreted as corresponding to "real" VTL values.</dl>
