Quais as diferenças perceptíveis? Algo além das escritas abaixo?Sometimes written English may use a more stilted (pompous) speech, which if you would use in spoken English you would be deemed as a snob or many people would think that you had taken leave of your senses.Or that you are a pedantic guy that want to show too much erudition all the time (a show-off guy).
1) Obviamente, existem fonemas, os quais distinguem a maneira de escrever e a de ler.As per wikipedia defintion:
A phoneme is a basic unit of a language's phonology, which is combined with other phonemes to form meaningful units such as words or morphemes. The phoneme can be described as "The smallest contrastive linguistic unit which may bring about a change of meaning". In this way the difference in meaning between the English words kill and kiss is a result of the exchange of the phoneme /l/ for the phoneme /s/. Two words that differ in meaning through a contrast of a single phoneme form a minimal pair.So, to me, phonemes is on the field of phonetics. (Phonetics is a branch of linguistics that comprises the study of the sounds of human speech, or—in the case of sign languages—the equivalent aspects of sign. -again - from Wikipedia.)
Thus, not in the the writing field, my thought here. Others may disagree.
2) Os relatives pronouns são normalmente emitidos em alguns casos na fala.I will leave that on others´court.
3) Connected Speech Ditto.
4) Contrações comuns na fala e incomuns na escritaThere are plenty on that subject on the Web. I´ll leave it to others.
Gostaria de conhecer mais algumas diferenças (General American English).Regional accents, personal dictions, the repertoire of a given individual, differences between ''Journalese" (news-speak) and normal speaking. Jargons from some professions, say, pilots, the computer guys, artist/singers, sport guys, etc"
And so on and so forth. You asked some, so I am not trying to bring ''all of them" to the table.
Others want to participate, I am certain of that.
