Using と to mark a question


I've been working on listening practice again. This time, I'm watching the
first episode of an anime series called スケッチブック 〜full color's〜.

In the first episode, a certain character asks three questions, and I think
all three end with `と`. I recorded them and [uploaded an
MP3](http://sandwich.quarplet.com/sora.mp3), and I attempted to transcribe
them:

>   1. あっ、空{そら}！ どこいくとー？
>
>   2. 空、何探しよーと？
>
>   3. 空、どうしたとー？
>
>

Here are my questions:

  * Is `と` a dialect equivalent of using `の` to mark a question?

  * Am I just hearing `と` wrong?

(I'm sorry if the whole transcription is wrong! I'm not very good at hearing
Japanese yet.)




The former. と can be used to mark questions in
[九州方言{きゅうしゅうほうげん}](https://ja.wikipedia.org/wiki/%E4%B9%9D%E5%B7%9E%E6%96%B9%E8%A8%80)
(in this case, she is speaking in
[博多弁{はかたべん}](https://ja.wikipedia.org/wiki/%E5%8D%9A%E5%A4%9A%E5%BC%81), a
subdialect). (More technically, it is a 準体助詞{じゅんたいじょし} like の, and shares the
nominalization property, which is probably why it can be used to mark
questions like that.)
