I couldn't play the video either...

When I speak fast, I think I may sound 'かいたありますよ' or even 'かいたりますよ'.

・・・Or maybe it's Kansai accent? We say '～たあります' instead of '～てあります' in Kansai area.

PS. But we never write that way.

PS2. I've just heard the video. It's NOT Kansai accent.

PS3. We often pronounce 'せんたっきsentakki' but write 'せんたくきsentakuki' (洗濯機) and never write 'せんたっき'.
