LANGUAGE WRITTEN AND SPOKEN,
WHICH ONE IS MORE IMPORTANT?

INTRODUCTION
As we already know for humans since childhood becomes easily to learn spoken language before written language. However, after learn how to speak, written language becomes more stable than spoken language, it is because human rely on their eyes more than ears. Since spoken language and it written form represent the same meaning, it is necessary to find out which is determinate and which is secondary. In this report will be explained which characteristic of the language is more important.

GENERAL ASPECTS
First of all, we must separate speech and writing. We know that speech and writing are two forms of human language. Speech and writing both represent meaning. They both possess language's property. To work around the concept 'language' that is a term for both speech and writing, we do not regard them as language, but as visual and auditory info. Apparently, the fundamental distinction between speech and writing is: speech is auditory (acoustic), while writing is visual.
Since we are born we are capable to learn real life sounds, so that we are also able to reproduce this sounds whereby spoken language may be more effective than written language on the other hand sometimes speech and writing are the same. Some people like writing more than speaking. Speaking is more important in public gathering, while writing more important for making notes. In terms of usage, neither of speech and writing has absolute advantage over the other. There is no mystery in speech and writing as we hear, see and use them. We choose writing or speech, whichever is more practical.

Written language requires one to give more attention to conventions of language. For example, in writing, we clearly mark when one sentence ends and a new one begins by using a period, also called a full stop, at the end of a sentence and by capitalizing the first letter of the next sentence. When a new sentence begins in spoken language might not always be apparent, though this is not to say that it is not ever apparent in spoken language. Speakers mark new thoughts and ideas by stressing or not stressing words, or we could say increases and decreases in volume rising and falling intonation.
Some spoken language is prepared, such as announcements, formal speeches, and formal presentations. In spoken language that is prepared, or partially prepared, speakers often rehearse what they say. Though they may or may not read directly from a prepared text, or partially prepared text allows speakers to piece together their thoughts and ideas in a way that is more representative of written language. By contrast, we observe that the sponteneity of conversational language does not always permit speakers to produce sentences that conform to what we would recognize as more organized forms of expression, such as that which we observe in written language.
There's more flexibility in spoken language. Listeners do not consider that a speaker may or may not have started a new paragraph. They do, however, recognize when a speaker has moved on to a new set of relevant thoughts and ideas. When people are face to face, they presumably communicate by talking but not writing. So that’s why we do not need an specific grammatical structure because as it was mention people can rely on our body and face expressions making it intuitive the process of the message transmitted.
Oral communication is emotional, filled with participants' laughers, excitement, sorrow etc. People observe each other's facial expressions and the surrounding situations. During writing and reading we only focus on the texts. As a result, speech appears more human and real, while writing is external symbols.
In written language is necessary to have a correct grammatical structure on the message that’s is going to be transmitted in order to give to the readers a clear idea about it also writing is recognize as a formal way of communication more than spoken language. However it does not happen always so. In addition to this in writing knowledge is more represent because it represent a status of the vocabulary and the alphabet that we commonly used, which makes a great difference between the spoken languages.
With terms of literacy, more and more knowledge is represented in writing. To date, most knowledge we got is from reading. Literacy contributed to the progress of society. Speech is mostly employed in presentation and interaction among people, in some occasions, important knowledge is obtained by listening. But usually this knowledge is of smaller amount. Although audio recording can spread as far and fast as text through internet, audio is mostly unattended. It is reading that builds solid knowledge of a person. It seems that writing is advanced whilst speech is primitive.
Spoken language is less structured and more relaxed, or casual, than written language, but we may only understand this to be the case because most spoken language is conversational, and conversational language does not require the same structure and organization as written language. Even so, depending on the circumstance in which one speaks and one's purpose in speaking, there are degrees to which our spoken language may be well structured and organized, and there are degrees to which it may or may not be relaxed or casual.
Often there are some clear distinctions between written language and spoken language, those distinctions are not present one hundred percent of the time. So what's the difference between spoken language and written language? We could comment more in an attempt to break it down in order to clearly define the difference. But maybe it's better to simply accept the ambiguity: spoken language and written language are different, but not all the time.
In fact, many researchers have pointed out the significant role of writing in thought. So literacy contributes to conceptual structure rather than only reporting it. However, speech is still considered primary that written language provides a model for. We hold that both the structure and content of thought are in writing itself. Meanwhile language is able to stand as unambiguous and autonomous representation of meaning. The development of this explicit formal system accounts for the predominant features and for our distinctive ways of using language and our distinctive modes of thought.
Knowledge transmitted via writing has by far surpassed that transmitted via speech. Speech's primary status seems to be challenged by the growing volumes of text. The writing as record of speech notion is agreed by many. It is intuitive instead of proven. However, the growing role of writing doesn't change its identity as artifact. Speech is associated with nature of mankind. It is integrated in people's thought. People hear voices in their brain when they are thinking. It seems that we think in the language we speak. To clarify the nature of speech and writing, it is essential to study language in thought. The relation between speech and writing is not preexisting, which is set up in human mind.

CONCLUSION
Knowing the relationship between spoken language and written language, written language determines spoken language, can help leaning knowledge and learning language. One sentence you must remember is: language is just a way for representing and exchanging knowledge or meaning.
Next thing is to read more texts possessing knowledge of personal interest and make correspondences to the writing. Today, many prevalent methods play much attention to listening and speaking, while ignoring the connections between writing and knowledge, it is not surprising they make little effect. Although writing determines the meaning, knowing its pronunciation and being fluent in speaking can make you read more quickly, and increase oral communication ability.
In a word, the main relationship between modern human spoken language and written language is simple human uses writing to represent the real world, when they speak out the writing, it becomes spoken language.
