What is the correct pitch accent for ううん?


For ううん to express negation,
[Weblio](https://www.weblio.jp/content/%E3%81%86%E3%81%86%E3%82%93) gives the
pitch accent as 【2】, i.e.

ううん 【LHL】

However, (to me) this doesn't sound like how people actually pronounce the
word. I've always thought that it sounded like this:

ううん 【HLH】  
(Listen [here](https://forvo.com/search/%E3%81%86%E3%81%86%E3%82%93/))

... but I know that is not a proper pitch accent pattern for Japanese. So I'd
be interested to hear what a native speaker feels the correct pitch accent
pattern for this word is.




The forvo.com resource you linked has samples provided by native speakers of
Japanese, and this is indeed the most common way to pronounce ううん in the
context of a negation (I can't say I'm aware of any dialect that pronounces it
differently, either). So yes, something like ううん{HLH} is correct.
