SPECIALIZATION OF THE HUMAN SPEECH APPARATUS CHAPTER I INTRODUCTION Language, as defined in Oxford Advanced Learner’s Dictionary, is system of sounds, words, patterns, etc. used by humans to communicate thoughts and feelings in a particular group or nation. System in this definition, according to Dardjowidjojo (2003), refers to the existence of elements related to one another which at last form a hierarchy constituent. In phonology, for example, those elements are the sounds existing in a language. Those sounds, then, form a system. Referring to the above definition, especially sounds, we may not realize that using a language is a completely difficult skill. The speech acts which are produced in the form of sounds through the air are actually very complex. We, then, will feel the difficulty if we hear someone talking in a foreign language and we do not know or understand the language well. In fact we have to try to analyze the speech acts produced in order that we can understand the meaning. One difficulty is that when someone talks, he will produce many words. It is estimated that in using English, a speaker will produce about 125-180 words per minute (Gleason and Ratner in Dardjowidjojo), while an Indonesian speaker will produce around 80-110 words per minute (Dardjowidjojo, 2003). Viewed from the the amounts of sounds speeched, it is found that when someone speaks he will speech out between 1500-1800 sounds per minute. The problem is how we can catch, and then analyze the sounds speeched out in the so called speedy. Another difficulty is that sounds in a speech act are not speeched one by one or separately, but they seem speeched out unitedly with other sounds. We, the listeners, are hoped to be able to separate which one follows which one. When the sentence Ed had edited it is pronounced normally, it will sound strange and funny, /ƐdhædƐditidit/, but the native speakers still can interprete it well. Specialization of The Human Speech Apparatus 1 The voice of a woman, a man, and a child is also different. A man’s voice will be ‘hard’, while a woman’s will be ‘high’. The differences, of course, will arise different voices, eventhough they pronounce the same word. The word sleep, which is pronounced by a man, a woman, and a child, will sound differently. However, we as the listeners still can interprete it as the same word. How can we do it? To answer the question, we, then, need to know how the speech acts are produced. CHAPTER II DISCUSSION Specialization of The Human Speech Apparatus 2 A. Human and Animal Language All creatures have a communication system that may make them live in a group, in a subgroup, and make them cooperate among others (Nababan, 1992). Not only humans, the animals also have the communication system, called language. It is, then, questioned whether the languages used by the humans and animals are the same or not. Dardjowidjojo (2003) states that there are some special characteristics which differentiate the humans language from the animals one, namely: 1. Human language has structure-dependence. One cluster of words in a sentence is not forming an unordered sequence, but one is dependent on the others. 2. Both the language and the users are creative. The users of the language are creative because they have ability to understand and produce new speech. While, the language is creative because its structure allows the users to manipulate the language in accordance with the existing rules. 3. The language can be used to express past phenomenon, future phenomenon, even imaginary phenomenon. 4. Language has double structure, namely: deep structure and surface structure. 5. The language is acquired continually, passing on from one generation to the others. 6. The relationship between the words and the thing, action, or situation they refer to is arbitrary. 7. Language has double pattern. It means the speeches mean nothing unless they are linked together. 8. The language has semantic concept. When a name is given, the name will always refers to the concept of the thing. B. Human of Speech Apparatus Specialization of The Human Speech Apparatus 3 The source of the sound is from the lungs. The air, pumped by the lungs through the larynx, goes out through the mouth or the nose. During the process, the air sometimes is blocked by one of the mouth parts until it is released out. The blocked air, then, produces sound. The air pumped out by the lungs passes through a place called glottis. This air, then, goes through a tube called pharynx. There are two ways in the pharynx: first, through the nasal cavity and second, through the oral cavity. The sound produced through the nose termed nasal, while the sound produced through the mouth termed oral. For the detail, it is shown in the following pictures. If the human head were cut in half down the midline, the organs of speech would appear like this: Specialization of The Human Speech Apparatus 4 Specialization of The Human Speech Apparatus 5 There are two parts in oral cavity: the upper part and lower part. Those parts are described as the followings. 1. Lips: upper lip and lower lip. These lips can be joined to produce sound called labial, for example [p], [b], [m]. 2. Teeth: the upper teeth can touch the lower lip to produce labiodentals sound, like [f], [v]. The upper teeth can also touch the tip of the tongue to produce dental sound, like [t], [d] in Indonesian. 3. Alveolar: this part is at the back of upper teeth ridge. The tip of the tongue can be put on the alveolar to produce alveolar sound, like [t], [d] in English. 4. Hard palate: a part in the upper mouth cavity, in backside of the alveolar. The front tongue can be put on this part to produce alveopalatal sound, like [c], [j] in Indonesian. 5. Soft palate or velum: this part is at the back side of the upper mouth cavity. The back part of the tongue can be put on this part to produce velar sound, like [k], [g] in Indonesian. 6. Uvula: a soft bone existing on the tip of the upper jaw. Uvula can move to block or open the tract to the nose. When uvula does not touch the upper part of the larynx, the air expelled through the nose and it produces nasal sound. On the other hand, when uvula touches the larynx, the air expelled through the mouth and it produces oral sound. 7. Tongue: a part which is located in the lower jaw, next to the lips and the teeth. There are some parts of tongue, namely: tip of the tongue, front tongue, and back tongue. These parts can be moved forward, backward, upward, or downward to produce certain sounds. 8. Vocal cords: a couple of membranes on the larynx. These membranes can be joined, spaced, or widely opened. 9. Pharynx: an air tract to the mouth cavity or the nose cavity. Specialization of The Human Speech Apparatus 6 10. Nose cavity: a cavity for nasal sounds. 11. Mouth cavity: a cavity for oral sounds. Figure : The upper part of the larynx C. How Speech Sounds are Produced As stated above that the sounds produced are grouped into nasal and oral sounds. As an addition, the sounds can also be grouped into consonant and vocal sounds. The differences are on the way of producing them. 1. Consonant sounds The sounds are produced by using the mouth parts like tongue, lips, and teeth. These parts are called articulators. There three things should be considered in producing consonant sounds. First, places of articulation, places on which the Specialization of The Human Speech Apparatus 7 articulators are located, joined, or put. When the upper lip and lower lip are joined, they will produce bilabial sounds. Sounds [p], [b], and [m] are the examples. The difference between the two first sounds and the last sound is on the sound tract they pass through: [p] and [b] pass through the mouth and they are called oral sounds, while [m] passes through the nose and it is called nasal sound. Below are the diagrams showing the processes. Specialization of The Human Speech Apparatus 8 Second factor is the way of articulation, how the air is expelled from the lungs. When the air is blocked in the mouth tightly, then it is expelled wholly, the sound will result plosive sound or stop sound. Sounds [p], [b], [t], and [d] are the examples. The third factor is the vocal cords status. As stated above that the vocal cords can be joined, spaced, or widely opened. When we are not speaking, the vocal cords will be widely open. When we produce sounds [p], [t], and [k], the vocal cords are quite open, but they are not voiced. Because the vocal cords are voiceless, the socalled sounds belong to voiceless sounds. However, when the vocal cords are quite closed and the air pushes them to get open, then there will be voice on the vocal cords. Therefore, the sounds produced with the vibrating vocal cords are called voiced sounds. Specialization of The Human Speech Apparatus 9 Figure : Places of articulation 2. Vocal sounds It is different from consonant sounds, the vocal sounds are produced based on the following criterion: (1) low or high tongue, (2) the tongue position, (3) the tongue tension, (4) the lips form. The upward and downward moves of the tongue will change the size of mouth cavity. When the tongue is high, the space through which the air passes will be narrow. The sound produced will also be high. When the tongue Specialization of The Human Speech Apparatus 10 is low, the mouth cavity will be wider, the lower the tongue, the wider the mouth cavity will be. The diagram below shows sounds /i/, /e/, and /Ɛ/. The tongue can also be folded forward or backward. The front and back positions of the tongue will also play an important role in producing vocal sounds. When it is combined with the high and the low tongue, the positions will produce certain vocals. The following diagram will show the production of sounds /u/, /o/, /ɔ/. Specialization of The Human Speech Apparatus 11 As an addition of the two criterion mentioned above, the tension of nerve when sound is produced will also affect the vocal sounds production. When we pronounce /i/ in beat, we can feel the tension of the nerve on our neck, but we will not feel the same tension if we pronounce bit. The fourth criterion is the form of the tongue. Certain vocals are produced by making the lips rounded or spread. Generally, the front vocal sounds like /i/ in tiba and /e/ in kare are pronounced with rounded lips, while the back vocal sounds like /u/ in buku and /o/ in ruko are pronounced with rounded lips. Figure : Vocal sounds Specialization of The Human Speech Apparatus 12 CHAPTER III CONCLUSION Based on the explanation in the previous discussion part, the writers put forwards several conclusions, namely: 1. The human language is different from the animal language. 2. The human speech apparatus are: lips, teeth, alveolar, hard palate, soft palate or velum, uvula, tongue, vocal cords, pharynx, mouth cavity, nose cavity. 3. The kinds of apparatus and the position of apparatus when sounds are produced will determine the kinds of the sounds themselves. 4. Nasal sounds, oral sounds, consonant sounds, and vocal sounds are the result of sounds production due to the kinds and position of the apparatus when they are produced.
