Dutch text-to-speech must master a set of guttural and diphthong sounds that have no close English equivalent: the hard "g" and "ch" fricatives, and the rolling diphthongs in "ui", "ij", and "eui". The same orthography is shared by two main standards — Netherlands Dutch and Belgian Flemish — which differ noticeably in rhythm and the realization of the "g", so a voice trained on one sounds foreign to the other. Dutch also forms long compound nouns and uses many spelling-rule vowel doublings (aa, ee, oo) that signal length, all of which the engine must parse for correct stress. The frequent assimilation and final-devoicing at word boundaries add a further layer the synthesizer has to model to avoid a clipped, list-like delivery.
