Sounds Really matter

Yes sounds totally matter in an language but so is the way of saying it. I think it is so interesting that some words in a language like Korean can have so little variations and signify something completely different. Similarly in Chinese, that slight bit of difference is crucial when spoken. From personal experience, traveling back to Asia, geography influences how people pronounce a language. Take Cantonese and Mandarin for example, they are all chinese but spoken with very distinctly.
