关于此声音
This is a brief, high-pitched aduh spoken in the twins' childlike voices, stretched into a whiny little groan that lasts under two seconds. It feels funny and gently embarrassed rather than painful, like a soft comic wince after a clumsy slip. The sound comes from Upin and Ipin, the Malaysian animated series about twin brothers, where aduh is a familiar Malay word for ouch or oh dear.
