Linguists do have a way of explicitly notating language, called IPA. However, just reading straight IPA can be exhausing. (dʒʌst ɹidɪŋ ai pi ɛi kæn bi ɛɡzɐstɪŋ). Not to mention, one's own accent comes through in the transcription. I remember in school i was confused by the utterance kœkəkœwlɐ which turned out to be "Coca-Cola" transcribed in a British accent (I'm from the US).
