The grammar of sounds

Phonology

How we use our articulators:Phonemes and allophones

• tuck• stuck• put• kitten• pitted• truck

Phonemes and allophones

• tuck [tʰʌʔk] aspirated• stuck [stʌʔk] released• put [pʊʔt] unreleased• kitten [kʰɪʔn� ] glottal stop• pitted [pʰɪɾed] flap• truck[tjɹʌʔk] palatalized

Phoneme

• A class of sounds with a unique grammatical (typically, distinctive) function

• k/kh are allophones in English; they are different phonemes in Hindi

[ki:l] ‘parched grain’ [khi:l] ‘nail’• s/z are different phonemes in English, they

are allophones in Italian

Phonology: the grammar of the sounds of languages

Sounds of the languages of the world are produced in a largely uniform way through a few choices in the phonatory apparatus (which, however, generate a large domain of possible units)

Towards a grammar of the sounds of language

• Different languages:

- select an inventory

- choose how to treat the sounds in their

inventory (e.g. as variants of the same unit

or as forming distinct units)• Grammar here means:

A calculus of how sounds patterns are created and decoded

Phonemes as class of sounds/phones(material/physical characterization)

• English voiceless dental stop:/t/ = { t, th, t, ʔt, ʔ , tj}

• Italian alveolar fricative:/s/ = { s, z}

• Japanese liquid:/r/ = { r, l}

Grammar takes over:Phonemes as feature structures

(‘mental’ characterization)• Given that sounds are produced in a

predictable way, we can imagine classifying them in terms of a set of articulatory/acoustic properties (‘features’ or ‘traits’)

• These arrays of properties are the building blocks of the instructions that grammar provides to the sensory/motor system

In other words,…

Grammar imposes structure on the auditory/articulatory system, and thanks to that structure it encodes meanings into sounds (or, in the case of sign languages, gestures).In so doing, it of course exploits/relies on the natural properties of our auditory/articulatory system.

Grammaticalization: Gender

• A man walked in. He was wearing a hat• A woman walked in. She was wearing a hat• I bought a table. It was expensive• Io ho comprato un tavolo. Lo ho pagato moltoI have bought a-m table-m. He-m (I) have payed-m a lot• Io ho comprato una tavola. La ho pagata moltoI have bought a table-f. She-f (I) have payed-f a lot

Grammaticalization: Number

• A dog is barking outside• Some dogs are barking outside• * Dog is barking outside• Waimian gou zai jiao• Outside dog PROG bark• A/some/the dog/dogs is/are barking

Grammar manipulates formal features

Semantic concepts (gender/number) maybe turned into ‘formal features’ that the grammar of the language keeps track of/manipulates

Formal here doesn’t mean ‘meaningless’. It means something that a computational device can and must manipulate

The same happens to sounds: phonetic/articulatory properties of sounds became formal features of a computational device

Feature matrices

1. Major class features

1.1. Syllabic: sounds that form a peak (nucleus) of a syllable. [+syll]: Vowels (but never glides) Consonants are normally [-syll] but syllabic Cs are possible.

1.2. Sonorant: resonant sounds. [+son]: vowels, nasals, liquids (laterals are sometimes excluded), glides (y, w), approximants. [-son]: all obstruents: stops, fricatives, affricates.

1.3. Consonantal: complete or very narrow constriction in the vocal tract [+cons]: stops, fricatives, affricates, nasals and liquids. [-cons]: vowels, glides, glottal stop, h.

2. Major place features

2.1. Labial: sounds, produced with a constriction of one or both lips. [+lab]: bilabials, labiodentals, rounded vowels, labialized consonants b, v, etc.[-lab]: t, k, etc.

2.2. Coronal: sounds produced with the tip or the blade of the tongue. [+cor]: dental, alveolar, retroflex, palato-alveolar [-cor]: labial, palatal, velar

3. Minor place features

3.1. Anterior: constriction is at or in front of the alveolar ridge. [+ant] : dentals, alveolars: t, n[-ant]: all others

3.2. Distributed: coronal sounds, produced with the tongue blade [+dist]: so called laminal sounds, e.g. ʒ, ʃ [-dist]: sounds produced with the tongue tip

4. Tongue Body Features

4.1. High: tongue body is raised[+hi]: All high vowels, glides, palatal and velar consonants.

4.2. Low: tongue body is lowered. [+lo] : low vowels, pharyngeal Cs

4.3. Back: Tongue body is retracted. [+back]: All central and back vowels, velar, and uvular consonants.

4.4. ATR: drawing the root of the tongue forward. Applies mainly to vowels. Sometimes this feature is also called [tense]. [-ATR]: are the lax vowels found in /bit, put, bet / etc. [+ATR]: are the tense vowels found in /who, leave/ etc.

5. Manner of Articulation Features

5.1. Nasal: sounds produced when the velum is lowered are nasal. All others are nonnasal.

5.2. Continuant: Sounds without complete obstruction are continuant. [-cont]: Stops, nasal stops, affricates, glottal stop.[+cont] Vowels, glides, liquids and fricatives.

5.3. Delayed release: used to distinguish affricates from other obstruents. 5.4. Strident: acoustic property of fricatives (‘high frequency turbulence’).

[+strid]: Labiodental fricatives, alveolar fricatives, palato-alveolar fricatives, uvular fricatives. f,v,s,z, ʒ, ʃ [-strid]: Bilabial fricatives, interdental fricatives, alveo-palatal fricatives, velar fricatives. All non-fricatives. β, θ, ð, x

5.5. Lateral: sounds produced with air flow over the sides of the tongue (used to distinguish l-sounds from r-sounds).

6. Laryngeal features (glottal state)

6.1.Voice: vocal folds vibrating. [+voiced]: Voiced consonants, sonorants, vowels

6.2. Constricted glottis: vocal folds are adducted [+constr]: glottalized, ejective and implosive consonants, glottal stop.

6.3. Spread glottis: aspirated and murmured consonants, h, voiceless vowels/glides

A consequence

Creative application of feature based rules:If you simply memorize forms, then one should use the default (-d) with novel phonemes (in, e.g., borrowings).If you apply a rule, -t or –d should surface depending on whether the new phoneme is voiced or not.

• He outbached even Bach himself

Sounds have a grammar

• With specific rules and representationsthat speakers’ communities may choose from

• Grammar is a way of describing the languages of the world

• And a model of the subconscious knowledge speakers have of their languages
