Well, thats a difficult question, because are you specific to just humans or animals? Plus the right answer is based on what you believe. Like if you believe God created everything, then animals were the first to speak, and then humans, well it did not specify in the Bible what they spoke. If you believe in evolution, animals were also the first to speak in their own language, probably through noises and body language

Baltic-Slavic languages include Latvian and Lithuanian, which are spoken (of course) in Latvia and Lithuania. Those countries are located on the Baltic Sea in northern Europe, sort of smashed between Scandinavia, Russia, and Poland.
