I usually refer to Cambridge Dictionary for pronunciation. For [*mental*](https://dictionary.cambridge.org/dictionary/english/mental?a=british#dataset-british) they have the IPA of:

> 
> mental
> ======
> 
> 
> *adjective* · UK /ˈmen.tᵊl/ US /-t̬ᵊl/
> 
> 
> 

When I click on the US pronunciation, I hear them saying /ˈmen.dəl/ with a D. You can see *mental* on Cambridge at [this](https://dictionary.cambridge.org/dictionary/english/mental) link.

But when I check the Longman Pronunciation Dictionary for the US pronunciation, I hear /ˈmen.təl/ same UK? You can see the pronunciation at [this](https://www.ldoceonline.com/dictionary/mental) link.

My question is, which one of those is right and which one of those wrong?
