bnik Knowledge of Sounds Phonology The study of

Phonology n n The study of the mental organization of a language’s sound system. Units of organization: – Biggest: syllables, syllables metrical feet, words – Middle: segments (phonemes and allophones) – Smallest: features

Segmental Phonology n n There are hundreds of possible speech sounds Each language only uses a few of these. What is of interest to phonologists is which sounds contrast Sounds contrast when their presence alone distinguishes forms with different meanings

The Minimal Pair Test n Two sounds contrast (or are distinctive) if you can find a pair of words that differ in only that sound, that mean different things. • [pæd] [bæd] minimal pair • Mean different things: /p/ and /b/ contrast • [pæt] [pæth] not minimal pair • Mean the same thing: [t] and [th] do not contrast

Crucial concept 1: Phoneme n When two sounds contrast they are part of different phonemes • /p/ and /b/ are different phonemes n n Phonemes are abstract mental units that represent sounds. Be careful! Phonemes are not sounds themselves, they are mental units representing sounds!!!

Crucial Concept 2: Allophones n Phonetic forms that don’t contrast (make a difference in meaning) are called allophones • [t] and [th] are allophones of the phoneme /t/ n Allophones are the various pronunciations of a phoneme.

Phonemes & Allophones n n Phonemes are written between / / brackets Allophones are written between [ ] brackets /t/ [t] phonemic (abstract/mental) category in your mind [th] allophonic (phonetic) realizations what you actually say

Language Specificity n n In English, [ph] and [p] are allophones of the same phoneme (/p/), meaning that a word doesn’t change its meaning if you substitute one sound for the other. For example: [phaj] vs. [paj] ‘pie’

Language Specificity n n But in Thai, [ph] and [p] are not allophones of a single phoneme; each is an allophone of a separate phoneme. For example: [p. AA] ‘aunt’ vs. [ph. AA] ‘cloth’ This is a minimal pair: two words that differ only in the pronunciation of a single sound. A minimal pair’s existence tells you that the sounds in question are separate phonemes in that language.

Language Specificity n The status as a phoneme is a language specific matter • English /p/ /ph/ [p] [ph] Thai

File 4. 4, Exercise 1. 1 Sindhi [pńu] leaf [b´d. Zu] run [bńu] forest [b´t. Su] be safe [phńu] snake hood There is a minimal pair (trio) between ‘leaf’, ‘forest’ and ‘snake hood’. Therefore /p/, /b/ and /ph/ are all different phonemes in Sindhi. There is a minimal pair between ‘run’ and ‘be safe’. Therefore /d. Z/, /t. S/ are different phonemes in Sindhi.

Sounds in context n n n The pronunciation of a phoneme is often determined by the other sounds around it. The nearby sounds around a phoneme are called the environment of that phoneme. E. g. in the word [pæt], [p__t] is the environment for the [æ].

Crucial concept 3: Complementary Distribution n When two phones are mutually exclusive, i. e. , they appear in different environments – [spæt] – [spul] n n [phæt] [phul] *[sphæt] *[sphul] *[pæt] *[pul] [ph] and [p] are in complementary distribution (which means they are allophones of the same phoneme). When sounds are in complementary distribution, you can predict where you get each sound.

Complementary Distribution n Another example: – [blu] – [glim] – [sl. Ip] – [fl. Ag] blue gleam sleep flog [pl 6 aw] [kl 6 Qp] [pl 6 ej] plow clap play

The mental concept of “supermanhood” (phoneme) In complementary distribution: never seen in the same place at the same time. Allophones!

NOT in complementary distribution: can both be present at the same time: allophones of different phonemes

Crucial Concept 4: Free Variation n When two sounds appear in the same environment, but don’t make a difference in meaning: [lip] leap [lip|] leap [sowp] soap [sowp|] soap Perceived as the same sound: another kind of allophony. This is called free variation.

How can I tell if two sounds are phonemes or allophones? Method 1 n Check for minimal pairs. If there is a pair then the sounds are separate phonemes n Check for complementary distribution. Are the sounds found in the same phonetic environment? If not, they are allophones of the same phoneme.

How can I tell if two sounds are phonemes or allophones? Method 1 n If two sounds are in complementary distribution then (a) figure out which one is predictable and which one is the “elsewhere” variant. The elsewhere variant is the symbol that we use for the phoneme /X/ [X] elsewhere Phoneme (in your mind) [Y] predictable same symbol Allophones (what you say)

How can I tell if two sounds are phonemes or allophones? Method 1 n and (b) write a rule that spells out where the predictable variant is found. • /X/ [Y] / environment ____ environment n A fairly rare situation: If the two sounds are in the same phonetic environment (and there were no minimal pairs!) Then they are possibly in free variation.

Method 2 data No List the environments of the sounds same environment? The sounds are in complementary distribution and are allophones of the same phoneme Yes The sounds are in free variation and are allophones of the same phoneme same meaning? No Minimal Pair: Pair The sounds are different phonemes

Sample problem: English long vowels Question: are long and short vowels in English allophones of single phonemes, or are they separate phonemes? (a vowel followed by the symbol [: ] is a long vowel) [phæ: d] ‘pad’ [phæt] ‘pat’ [hu: d] ‘who’d’ [hut] ‘hoot’ [mi: d] ‘mead’ [mit] ‘meet’ [row: m]‘roam’ [rowp] ‘rope’ [ti: D] [ti. T] ‘teeth’ teethe [flu] ‘flew’ V: _d _m _D V Is there any overlap between the columns? _ t _p _T _# Are there any minimal pairs? NO! (There are no examples that differ in ONLY one sound!) Do long and short vowels occur in the same phonological environment? NO! Therefore, these are in complementary distribution and each long/short vowel pair represent allophones of same phoneme.

English long and short vowels, continued. . . n n n What is the rule for vowel lengthening in English, based on the data we just saw? To answer this question, we must make a generalization about the environment in which we find long vowels. The generalization is… – English vowels are long before a voiced consonant.

Phonological Rules n When the distribution is predictable, we can write a rule that represents this distribution. n These rules are part of your knowledge of language.

Phonological Rules n The rules take the form: elsewhere predictable / environment n n English long vowels: /V/ [V�] / ___ Cvoiced This rule expresses a generalization about what the speaker of English knows about their language.

Sample Problem: Tojolabal n 1. kisim my beard 2. k'i. Sin warm 3. sak white 4. ? ak' read are [k] and [k'] allophones of the same phoneme? No, we have 2 near-minimal pairs here. (Same environment for sound)

Summary n Phonemes, abstract mental unit of sound • Distinctive/contrastive: minimal pairs n Allophones: variant forms of a phoneme • Complementary distribution: different environments • Free variation: same environment but no diff in meaning n Forms in complementary distribution are predictable by rules.
