Finnish is in the Finno-Ugric family, not an Altaic language (at least according to the wiki, there are no mentions of Altaic for the Finnish entry, or vice versa).
In any case, it's completely different than anything most people ever heard (I've been living in Finland for close to 5 years, and it just hasn't clicked for me yet, despite being very fluent in 3 languages and dabbling in 3 others).
