An obvious difference between speech and writing is the fact that speaking is listened to and talked, whereas writing is read and hand-written or typed. These are not, however, the only distinctions when it comes to speech and writing; in fact there are many differences.
Age is one the main differences. Speech has been around for millions of years; quite possibly since life as we know it began on earth. Writing, on the other hand, is thought to have been invented far more recently than that, although still a long time ago in relation to today's fast-paced world, in approximately 3200 BC.
Without getting too embroiled in the whole nature/nurture debate; speech is arguably almost an innate function of human beings, in that we are born with the ability to do so. Most humans will learn to talk within the first two years of their life; learning almost an entire language by the age of five. Writing on the other hand, is said to be an acquired skill which develops after learning to talk. It is believed that globally, all humans can communicate in some kind of spoken form, whereas there are still tribal groups today who do not have the ability to write.
Until fairly recently (when recording devices were invented) speech could not be kept in its original form and heard back once it had been spoken. Writing, on the other hand, has enabled humans to record changes for many thousands of years. Even though we now have the capability to record sound bites to take through into the future, it is highly likely that text and writing will still outlast the recorded snippets which we may leave behind.
