to think a Nintendo DS should recognise a Scottish accent?

[AvadaKedavra]

Bought my DH a Nintendo DS for Christmas but having trouble with it as he is Scottish and the darned thing doesn't register his voice

AIBU to throw it through the window?

YABU. This human struggles to understand a broad accent of any type (and sometimes has mistaken a Scottish one for an Irish one and vice versa ), so what chance does a machine have
