Here you have the benefit of hearing Alexander Graham Bell pronounce not only his own name, but his middle and last name as well. It is interesting that he pronounces his given name in the American manner — Al-ex-zan-der. Bell was born and raised in Scotland. In the UK and Australia, you may often hear the name pronounced Al-ex-zahn-der.
The Spanish version is Alejandro (al-e-han-dro). In France, the e and r reverse positions and then when you say it, you just ignore the r and the e altogether, like so: al-ex-zahnd!
