Apparently, the BBC has a BBC Pronunciation Unit dedicated to telling people how to pronounce things. Here's everyone's favorite Iranian president:
Today's pronunciation is Iranian President Mahmoud AHMADINEJAD (sometimes also spelt AHMADINEZHAD). Our recommendation is mah-MOOD ah-mad-in-uh-ZHAAD (-h is pronounced in 'Mahmoud' and in 'Ahmadinejad') based on the advice of the BBC Persian Monitoring team.
It seems I've been saying "Siniora" all wrong.
