Different languages According to Professor Vyacheslav Ivanov of UCLA, there are at least 224 identified languages spoken in Los Angeles County. This does not include differing dialects. Professor Ivanov estimated that publications are locally produced in about 180 of these languages. He further believed that the linguistic landscape of Los Angeles may even be important for the study of the world's languages. He explained that, although there were about 6,000 known languages in the world in 2000, 90% of these would vanish within a generation. That would leave only about 600 languages in the world, a third of which continue to be spoken in Los Angeles.
