DIPHTHONGS AND TRIPHTHONGS

This unit is about diphthongs and triphthongs. Diphthong is combination of two vowels that make a sound. The numbers of diphthongs are eight that are / Iə, eə, ʊə, eI, aI, ɔI, əʊ, aʊ/. Also, these diphthongs are form with tree vowel sounds that are /ə/  this sound is centring position. For example Iə, eə, ʊə, and /I,ɔ/  these sounds  are closing. For example, eI, aI, ɔI, əʊ, aʊ   .Triphthongs are combination one vowel to another and then to a third, producing one sound. For example eI+ ə= eIə, layer, aI+ə= aIə liar, ɔI+ə =ɔIə loyal ,əʊ+ ə=əʊə lower, aʊ+ə= aʊə.

LONG VOWELS

 This unit is about long vowels. English language has five long vowels sounds such as: iː,aː,uː,ɔː,ɜ ː. The main characteristic is that long vowels sounds are followed by the voiced consonants sounds. For example /b,v,g,z/ sounds. Also, in this unit studies the position that have each one such as:” iː it is closer and more front, aːthis is an open vowel, and the lips position is neutral, uːit is much less back and less close,ɔːthe tongue height for this vowel, closer to the latter and ,ɜ ːit is a mid central vowel which is used in most English accents”.

THE PRODUCTION OF SPEECH SOUND

This unit is about articulator above the larynx. This unit studies the parts of the body and organs that help us to make sounds. The organs along with the breath that comes from the lungs work together to produce sounds such as: pharynx, soft palate, hard palate, alveolar ridge, tongue, teeth and lips. Beside in this unit we find a little introduction about short vowels and consonants sounds. Vowels sounds are sound in which there is not obstruction to the flow of air it passes  from the larynx to the lips, and consonants sounds depend when each one are produce.

INTRODUCTION

  

This unit is about the introduction of English phonetics and phonology. This unit refers how English is pronouncing, and its principal’s elements that help that this process develops such as: the production of speech sound. It represents all organs that produce different sounds that we make when we speak. For example /b/sound is produce for lips Besides, Phonemes and phonetics, these elements are different. For example, phonemes use slashes //, and phonetic use [ ]. Another is the place of articulation that has all consonants and vowels as /f/ sound is labiodental and voiceless. Finally, Accents and dialects. This about different accents that produced by people from different geographical place. For example American English and British English.
