Phonetics Vs. Phonology Whereas syntax is about sentence formation, and semantics about sentence interpretation, phonetics and phonology cover the field of sentence utterance. Phonetics is concerned with how sounds are produced, transmitted and perceived (we will only look at the production of sounds). Phonology is concerned with how sounds function in relation to each other in a language. In other words, phonetics is about sounds of language, phonology about sound systems of language. Phonetics is a descriptive tool necessary to the study of the phonological aspects of a language.

The Three Main Branches of Phonetics Articulatory Phonetics : articulatory phonetics is interested in the movement of various parts of the vocal tract during speech. The vocal tract is the passages above the larynx where air passes in the production of speech. In simpler terms which bit of the mouth moves when we make a sound. Acoustic Phonetics: This is the study of the sound waves made by the human vocal organs for communication and how the sounds are transmitted. The sound travels through from the speaker's mouth through the air to the hearer's ear, through the form of vibrations in the air. Phoneticians can use equipment like Oscillographs and Spectographs in order to analyse things like the frequency and duration of the sound waves produced. Acoustic phonetics also looks at how articulatory and auditory phonetics link to the acoustic properties. Auditory Phonetics : This is how we perceive and hear sounds and how the ear, : brain and auditory nerve perceives the sounds. This branch deals with the physiological processes involved in the reception of speech.

Goals of any Phonetic Theory Any phonetic theory should account for: 1 - Any kind of noise that the human vocal apparatus is capable of producing (e. g. grunts, groans, and laughter). 2 - Linguistically significant sounds in language in general. 3 - Linguistically significant sounds in a particular language (e. g. English).

1 - Place of Articulation

2 - Manner of Articulation Manner of articulation concerns the types of obstruction that can take place in the vocal tract. There are two main places where such obstruction takes place. One is the glottis and the other is the oral cavity. The two operate independently from one another and may act simultaneously.

Obstruction in the Glottis 1 - Voicing and the glottis : in the production of speech, the main importance of the larynx lies in the fact that it contains the vocal bands (vocal cords). The vocal bands consist of two horizontal folds of elastic tissue, one on each side of the passage.

In normal breathing, the vocal bands are open, but it is possible to close them partially or completely during the production of a sound. The bands may be brought together so they vibrate as air passes through them. This vibration accounts for the feature of voicing (e. g. [z], [v], and [b] are classified as voiced sounds). If the vocal bands are open and not vibrating during the production of a sound, it will be a voiceless sound (e. g. [s], [f], and [t]). It is possible to completely close the vocal bands and release them in a rather abrupt manner. The resulting sound is referred to as glottal stop, symbolized as [ʔ].

Obstruction in the Oral Cavity Obstruction in the oral cavity has to do with the kind of obstruction the air meets on its way out, after it has passed the vocal folds.

Description of Vowels are described in terms of: 1 - Tongue Position 2 - Length 3 - Rounding 4 - Nasality 5 - Diphthong

1 - Tongue Position Tongue position is described using two criteria: the height (how high is the tongue) and the part of the tongue involved in the production of the sound. In English the tongue may either be high , i. e. when the speaker produces e. g. [i: , u: ] in [bi: t, bu: t] beat , boot , intermediate , e. g. [e, N: ] in [bet, b ᴐ: t] bet , bought , or low , e. g. [æ, a: ] in [b æt, ba: rt] bat , Bart. The part of the tongue involved in the production of a vowel can also be illustrated with the examples above. If you say [i: ] and then [u: ] just after it, you almost have the feeling that you are moving your tongue backwards. This is because [i: ] is a front vowel, and [u: ] is a back vowel, or in other words, the highest point in the pronunciation of [i: ] is the front of the tongue, whereas the highest point in [u: ] is the back of the tongue.

4 - Nasality 5 - Diphthongs

The basic Unit in Phonology : The Phoneme A phoneme is a basic unit of a language's phonology, which is combined with other phonemes to form meaningful units such as words or morphemes. The phoneme can be described as "The smallest contrastive linguistic unit which may bring about a change of meaning". In this way the difference in meaning between the English words kill and kiss is a result of the exchange of the phoneme /l/ for the phoneme /s/. Phonemes are abstract units of a set of speech sounds (i. e. phones)which are perceived as equivalent to each other in a given language. Notation: Phonemes are conventionally placed between slashes in transcription, whereas speech sounds (phones) are placed between square brackets. Thus /pʊʃ/ represents a sequence of three phonemes /p/, /ʊ/, /ʃ/ (the word push in standard English), while [pʰʊʃ] represents the phonetic sequence of sounds [pʰ] (aspirated "p"), [ʊ], [ʃ] (the usual pronunciation of push).

Phones and allophones Phones are the actual speech sounds. It is a speech segment that possesses distinct physical or perceptual properties, and serves as the basic unit of phonetic speech analysis. A phonetic transcription is enclosed within square brackets ([ ]), rather than the slashes (/ /) of a phonemic transcription. In phonology, an allophone is one of a set of multiple possible spoken sounds (or phones) used to pronounce a single phoneme. For example, [pʰ] (as in pin) and [p] (as in spin) are allophones for the phoneme /p/ in the English language. Changing the allophone used by native speakers for a given phoneme in a specific context usually will not change the meaning of a word but the result may sound non-native or unintelligible.

Minimal pairs and near minimal pairs to discover phonemes Minimal pairs and near minimal pairs are the simplest procedures to discover which sounds of a language are contrastive (i. e. different phonemes not allophones). Minimal pairs : a set of two or more words that have the same sounds except for one sound are different in meaning (e. g. sin , pin, bin, and chin). Near minimal pairs: words that have the same sounds except for 2 sounds and have different meanings (e. g. /f. Iʃin/ (fishin’)and /v. Ižin/ (vision)).

Complementary distribution to discover allophones Complementary distribution is the relationship between two different elements, where one element is found in a particular environment and the other element is found in the opposite environment. It often indicates that two superficially different elements are in fact the same linguistic unit at a deeper level. For instance, in English, [p] and [pʰ] are allophones of the phoneme /p/ because they occur in complementary distribution. [pʰ] always occurs when it is the syllable onset and followed by a stressed vowel (as in the word pin). [p] occurs in all other situations (as in the word spin).

Free Variation There are instances where phonetic variants are both non-contrastive and not in complementary distribution. It is the phenomenon of two (or more) sounds or forms appearing in the same environment without a change in meaning and without being considered incorrect by native speakers. In these cases, a speaker may use two or more of the allophones in the same environment. For example, the word stop may be pronounced with a plain unaspirated [p], [stɑp], or with a glottalized [pˀ], [stɑpˀ]. Phonemic Fluctuation: It is the situation when two different phonemes alternate without causing a difference in meaning. For example; ‘either’ is pronounced as [i: ðər] and [ayðər].

Phonological Processes Assimilation Deletion Epenthesis Metathesis

Assimilation Definition: is a linguistic process by which a sound becomes similar to an adjacent sound. Degree of assimilation: Partial or complete. In Partial assimilation, a sound takes on some of the characteristics of a neighboring sound (e. g. the plural /s/ in cats and cabs takes the voicing feature of the preceding sound, [kæts] Vs. [kæbz]). In complete assimilation, a sound takes on all the characteristics of a neighboring sound resulting in a process called geminatation (e. g. [g. Immi ‘give me’], [lɛmmi ‘let me’], and [gubba. I ‘good bye’]. Direction of assimilation: Assimilation is either progressive (i. e. the assimilated sound follows the conditioning sound), or regressive (i. e. the assimilated sound precedes the conditioning item). Conditioning Sound →Assimilated Sound = Progressive assimilation Assimilated Sound ← Conditioning Sound = Regressive assimilation

Deletion Definition: Sounds that occur in some contexts are lost in others. Deletion changes the syllable structure of a word. Subtypes of Deletion: A. Haplology: An entire syllable is lost when it is identical to another syllable (e. g. adjectives ending in – ly, such as lively and friendly). When these are used as adverbs, the addition of the adverbial suffix –ly results in two identical syllables (i. e. livelyly and friendlyly). Haplology resolves such cases by deleting one of the identical syllables resulting in friendly and lively.

B. Aphesis: refers to the loss of an unstressed initial vowel or syllable (e. g. about →bout / around → round/ because →cause). C. Syncope: is the loss of a medial vowel or syllable (e. g. evening →ev’ning/ every→ev’ry). D. Apocope is the loss of a final vowel or syllable (e. g. singan →sing / finde →find).

Epenthesis Definition: epenthesis is inserting a sound segment. Both vowels and consonants may be inserted (e. g. the vowel in the plural /Iz/ in buses [bʌs. Iz], the vowel in the past tense /Id/ in waited [wet. Id], the consonant [p] in attempt →[ətɛmpt]/ comfort → [cʌmp]fort/ non standard pronunciation of chimney → chimbly and family→fambly).

Metathesis Definition: it is changing the linear order of the segments by permutations of one type or another. That is, two segments reverse positions (e. g. ask →aks ‘ask’ / pr. Islraᴵb→p. Irskraᴵb ‘prescribe’/ hʌndr. Id→hʌnd. Ird ‘hundred’).
