INTRODUCTION PHONOLOGY According to Macmillan English Dictionary for Advanced Learners, phonology the study of the pattern of speech sounds used in a particular language. Also we can define phonology as the study of how sound is structured in languages -- for instance, which of all possible speech sounds a language uses to build its words, how syllables are built in a particular language, and other phenomena. Phonology is a branch of linguistics concerned with the systematic organization of sounds in languages. It has traditionally focused largely on study of the system of phonemes in a particular language. The mission of phonology is to understand how speech sounds and phonetic features are organized in a language so that they can be used to create contrast from phoneme. PHONEMES These are the different sounds within a language. Although there are slight differences in how individuals articulate sounds, we can still describe reasonably accurately how each sound is produced. One sound rather than another can change the meaning of the word. It is this principle which gives us the total number of phonemes in a particular language. (Fremkin, 2007) Features of phonology: Look beyond the individual segments at the sound system of a language Features to characterize speech sounds in the language of the world Some features are relevant only for consonants while others are only for vowels There is relationship between systematic organization of sounds in English and in Swahili language. Therefore following are the comparisons between these two languages VOWELS Sounds that you make when you speak without closing your mouth.( Macmillan English Dictionary, 2004) There are five vowel phonemes (distinctive sounds) in Swahili a, e, i, o and u .there are important differences between English and Swahili vowels. For example the Swahili vowels are short and not diphthongized as are the comparable of English ones. For instance Swahili “e” is comparable to the English vowel say without the lengthening or diphthong it also similar to the vowel in set but not quite as low with these differences in mind, note the following comparison. Swahili English Examples a ah! Baba Father e Say Wewe You i Be Kiti Chair o Ho Moto Fire U Too Tu Only Just Standard Swahili have five vowels phonemes: /a/, /∑/, /i/, /ↄ/,/u/. The pronunciation of the phoneme [u] and [o]. Vowels are never reduced, regardless of stress. The vowels are pronounced as follows: /a/ is pronounced like the ‘a’ in father /∑/ is pronounced like the ‘e’ in bed /i/ is pronounced like the ‘I’ in ski /ↄ/ is pronounced like the ‘o’ in cord /u/ is pronounced like the ‘u’ in rule Consonants Consonants in Swahili generally have English values but as in the case of vowels there are considerable differences note the following. 1. P, t, k. There are similar to English voiceless stops, but they can be aspirated or unaspirated. That is speaking the first two words below would release a burst of air that would rustle a sheet of paper held in front of the speaker’s mouth. For the second set of words, the sheet of paper would remain still. Generally initial p, t and k of class 9/10 nominal are aspirated in contrast to initial p, t and k of class 5 nominal. For example: Paa [p(h)aa] ‘gazelle’ Kaa [k(h)aa] ‘crab’ Versus: Paa (roof) passport Kaa (piece of charcoal) car 2. b, d, g. as English voiced stops but they are imploded that is in their pronunciation the air is sucked into the mouth as they are released. The ‘g’ is always hard as in English ‘goat’ versus the ‘g’ in gin. For example, Baba (father) Barber Dada (sister) diet Gumu (hard) goat 3. F, v, s, z. F as in English ‘far’ V as in English ‘very’ S as in English ‘sister’ Z as in English ‘zoo’ Fupi (short) fine Kavu (dry) calm Vizuri (well) virus Sasa (now) sun 4. M, n. As in English .in some cases where they occur before other consonants ‘m’ and ‘n’ are pronounced as full syllables but without inserting a vowel sound either before or after. The first two examples are syllabic but not the second two. Mtu (person) import Nta (wax) Versus Mboga ‘vegetable’ Ndege ‘bird, airplane’ 5. ny. As the segment ‘ni’ in English ‘onion’ Nyanya (grandmother) Ninyi ‘you’ (plural) 6. ng. As the ‘ng’ in English sing, single (not as finger). Example, ngo’mbe (cow) The same sound but spelled with ‘n’ is also heard before ‘g’ e.g. ngoma ‘drum’. Linguist represents this sound with the phonetic symbol for a velar nasal, thus ngo’mbe is [ (symbol) + ombe] and ngoma is [(symbol) + goma] 7. ch As the first sound in English ‘cheek’ not as in chemist Example,Chakula (food) Chache ‘few’ 8. j as in English ‘job’ but without the audible friction associated with the English consonant, some speakers of English hear this sound when pronounced by a native speakers as ‘y’ however a fairly accurate pronunciation can be achieved by pronouncing it as the sequence ‘dy’ Hujambo (hudyambo) ‘hello’ Jana (dyana) ‘yesterday’ 9. W, y, h. Some people are spell Swahili ‘h’ with ‘kh’ which symbolized (s) a sound similar to the ‘ch’ in Scottish ‘och’. This occurs frequently with Arabic borrowings but is not the practice followed in this manual. Watu (people) water Yeye (he or she) yesterday Huyu (this one or this person) whole 10. r Swahili (r) is quite different from the English one it is similar to the Spanish tapped ‘r’ as in ‘pero’ but or ‘daro’- of course. For example: Habari (news) rim Heri (good will, blessing, and good wishes) read 11. l As in English when in initial position e.g. ‘leak, loud, lesson’ second language learners tend not to distinguish r and l. Lala (sleep) Leo (today) 12. th As in English “thought, think” Thelathini (thirty) l 13. dh As in English though, thy, thee, then, e.g. Dhani (think) 14. gh This sound is pronounced by pronunciation ‘g’ as in a fricative it is similar to the in Scottish ‘loch’ but voiced E.g. Ghala ‘storehouse’ Ghali ‘expensive’ 15. sh As in English ‘push’. This sound plus kh, dh and gh are in words that have been borrowed into Swahili predominantly from Arabic e.g. of ‘sh’. Ishirini (twenty) Mshahara (salary) 16. mw A combination of m followed immediately by w Example, Mwalimu (teacher) Mwanafunzi (student) 17. bw A combination of b w and w Example, Bwana (sir or Mr.) Mbwa (dog) CONCLUCSION According to the observation which we have done, Kiswahili language seems to lack diphthong sounds and this may be the big difference from English language with eight(8) diphthong sounds as we have seen above. This may be even in other languages which we have not included in our study instead we have based only in these two languages, Kiswahili and English. REFERRENCES Fremkin, V.
