In Swiss German, "Da da da? Da da da. Da da da da!". A conversation between two women from Schleitheim on a train discussing whether a toddler is allowed to lick the windowpane: "He's allowed to do that?" "He can do that." "That you let him do that!". (In German: "Darf das [Kind] das [tun]?" "Das [Kind] darf das [tun]." "Dass das [Kind] das [tun] darf!")
The accent means you stress the letter. I really don't know how else to explain it, but if you speak/know any French or Spanish, then I'll explain it to you.
