Slovenian (also called "Slovene") is a Slavic language (no surprise there). Only 2.5 million people speak Slovenian; there are more than that many people living in Chicago, IL. Most Slovenian speakers live in Slovenia. It's the first language of about 1.9 million people; there are more than that many people living in Houston, TX.
That doesn't mean it's an unimportant language. To 2.5 million people, it obviously is. But it's not a widely spoken language. That said, Slovenian is one of the EU's 23 official languages.
If you're an American traveling to Slovenia, you may encounter some people who speak English as a second language. Some tips on communicating with them (can also help with English speakers in the USA!):
Clearly annunciate your ending consonants. Midwesterners in the USA tend not to do this.
Use short words. They are easier to understand.
Speak a bit more slowly than usual. Your Slovenian counterpart can probably understand your rapid speech, but the opposite may not be true. By speaking more slowly and deliberately, you help slow the other person down so you can understand.
If you don't quite understand, ask the other person to repeat. But don't shout. The problem isn't deafness, but a difference in articulation.
Use the correct date format. In the USA, many people use a date format that is unclear to the rest of the world. Rather than say "3-9-2014," say "09 MAR 2014" or "03 SEP 2014" depending on which date you actually mean.
