Speech is phonemic and made up of sounds, whereas writing is graphemic and appears to be just marks on a surface. Take the words FLOOD, BOOK and SOON for instance. In each word the “oo” has different sounds, but when looked at upon a piece of paper they appear to look the same. Also, with some words, the sound may actually be the same but when written down the words look dissimilar to one another. For example, NO, THOUGH, SEW, TOE and SHOW.
There are many paralinguistic and prosodic features which are not available in writing but which are in speech. Volume, gesture, eye contact, stress, rhythm and intonation are all useful and important features in speech, which are difficult to replicate in writing. Punctuation can be used to some extent to convey stress and intonation. Intonation can enable the communicative function of an utterance to differ from its grammatical form. Eg:
He saw you today - form: statement
- function: statement
He saw you today - form: statement
-function: question
Differences in intonation can also convey differences in meaning. This can occur in two ways: (1)the position of the stressed syllable within the intonation unit: or (2)the occurrence of intonation boundaries. Eg:
(1) You could call him at the office
You could call him at the office
You could call him at the office
(2) He washed / and brushed his hair
He washed and brushed his hair
Intonation can also convey the attitude of the speaker. However, in writing, the intonation can only be conveyed by the choice of vocabulary.
This isn’t to say that writing doesn’t have its advantages. There are some features of writing that have no counterpart in speech.
There is the problem of having to identify the word boundaries in speech whereas this is not usually the case in written form. For example, a grey day could be assumed in speech as “a grade A”. Similar to this, uses of punctuation like apostrophes can aid in understanding in writing which in speech may seem unclear. Eg:
He saw the ship’s sail.
He saw the ship sail.
In writing clever visual puns can be used to enhance a phrase and attract the reader, such as “John’s Plaice” for a fish and chip shop or “Grate Cheese” for a cheese making company. In speech this can only be done if the pun is explained.
There is also the case of accent and dialect. With most people, when they talk, you can tell where they come from by their dialect. It gives you an insight into what class they are, where they are from and gives you an idea of their character. However with writing it is not usual to write in dialect unless the writer is purposely trying to portray a certain type of character. Childrens’ early attempts at writing often appear more like transcribed speech because they have not fully grasped the differences between writing and speech and have not gained mastery of the more formal aspects of writing.
Speech and writing are both forms of communicating but both have differing qualities. There are major differences that have been outlined above which require different approaches by the person communicating. To be a successful and competent writer requires mastery of Standard English. Only when this has been achieved can a writer break the usual rules for stylistic reasons.
