ありがとう pitch and intonation


NHK日本語発音アクセント辞典 seems to only list ありがとう{LHLLL}. And I think the polite form
is most commonly ありがとうございます{LHLLLLHHHL}?

But I think I also hear what sounds to me like ありがとう{LHHHH} or ありがとう{LHLHH}.
Is it an intonation issue?

Some examples:

  * Am I correct in thinking [this one](https://youtu.be/oRCsy25ER64?t=231) is 語尾上げ? 「君、今日も頑張ってくれてありがとう」
  * What about [this one](https://youtu.be/IBrUxfKQdEA?t=975)?
  * And [this one](https://youtu.be/zwW9qvs2M50?t=859)
  * [This](https://youtu.be/alM-g--UJt4?t=778)
  * [This](https://youtu.be/W__7mkTAYiI?t=363)
  * I'm not sure if [this one](https://youtu.be/YHzoGWjcLRg?t=530) is ありがとうございます{LHHHHHHHHL}




I think all of your clips can be explained by:

  1. Quoting と or とか can make the previous word 尾高 sometimes.
  2. You have some non-標準語 clips. For instance, it's ありがと＼う in Kansai-ben. <https://youtu.be/yqWcakJhaok?t=605>
  3. The last clip sounds like あり＼がとうございま＼す to me.

It's not a good idea to use TedX talks from different parts in Japan as a
reference for standard pitch.
