Linguistics l.jpg
Linguistics

  • The study of language may treat a language as a self-contained system; or it may treat it as an object that varies over space, time, and social class.

  • We will consider only the first (and ignore diachronic linguistics and sociolinguistics).


Another distinction to bear in mind l.jpg
Another distinction to bear in mind

Language

  • We can study the way in which language organizes thought and expresses statements about (perceived) reality; or,

  • We can study the internal structure of language systems.

    I'll focus on the second. We will aim to determine the distribution of items in particular languages; and to establish any universal principles that can be extracted from those to simplify the entire process.

Perceived

reality


Slide4 l.jpg

Bear in mind...

English

…that English is an outlier among languages...

(This is really because

almost all of the volume

of a hypersphere becomes

arbitrarily close

to the skin, as the

dimensionality increases)

Language


Slide5 l.jpg

  • We humans manage to analyze an extremely complex acoustic signal and translate it into an internal representation linked to meaning with little conscious awareness of the intermediate steps or the complexity of the operation.


Slide6 l.jpg

Linguistics

Phonetics: sound, described as an acoustic and articulatory event

Phonology: the study of systems of discrete sounds

Morphology: ... the internal structure of words

Syntax: ...the principles governing combinations of words.

Semantics:...the relationship between syntactic structures and meaning.


A list of false statements about speech l.jpg
A list of false statements about speech

  • The speech stream can be divided into words on the basis of short pauses between words.

  • The speech stream can be divided into words on the basis of something acoustic.

  • Words can be divided into individual sounds on the basis of their acoustic properties.

Language is fast l.jpg
Language is equal length.fast!

  • Individual sounds can go by extremely fast (40 to 200 msec) and yet be easily grasped by the native speaker. There’s nothing else that I know of that we can do anywhere near that fast that appears to be under conscious control.

  • Native speakers reconstruct sounds from extremely degraded sensory input:

    • Jeetjet? Nah, juw?

Language is a brain function l.jpg
Language is a brain function equal length.

Since 19th century, we’ve known about

  • Broca’s area (posterior inferior frontal lob) (damage leads to nonfluent speech, lack of grammatical markers)

  • Wernicke’s area (left temporal lobe, auditory association area). Damage leads to aphasia with fluent speech lacking in content.



But what is language l.jpg
But what equal length.is language?

  • A system of great complexity

  • Much of the complexity is learned (we know that, because it is “language-specifïc”)

  • It still eludes our attempts to accurately model it on computers (witness continuous speech recognition products).


1 phonetics l.jpg

1. Phonetics equal length.


1 phonetics16 l.jpg
1. Phonetics equal length.

  • We know more about how sound is produced than how it is perceived, generally speaking.

  • Source-filter model: Upon exhilation, the vocal cords vibrate freely if there is little blockage or obstruction through the mouth and nose. The frequency of that vibration is the fundamental frequency (50-200hz in males, double that in females).


Articulatory apparatus l.jpg

Vowels l.jpg
Vowels equal length.

  • For vowels, the mouth/nose acts as an echo chamber, enhancing those harmonics that resonate there.

  • These resonances are called formants. The first 2 formants are especially important in characterizing particular vowels.

Vowels crudely l.jpg
Vowels, crudely… equal length.

  • To identify a vowel is to identify its location in a 2-dimensional F1-F2 space.

    Improvements:

  • … in 3-dimensional F1-F2-F3 space

  • …normalized by

See e.g. Harvey Sussman, The Neurogenesis of Phonology

Phonological processes and brain mechanisms 1988


Consonants l.jpg
Consonants equal length.

  • Stops: p, t, k, b, d, g

  • Fricatives, affricates: ch, j, sh, th...

  • Nasals: m, n, ng (as in sing)

  • Stops and fricatives create their own turbulence, and the oral shape determines what spectrum is enhanced.


Spectral character of sounds l.jpg
Spectral character of sounds equal length.

  • Stops show rapid change of formant frequency from their position to that of the neighboring vowel;

  • Fricatives should wide band of noise

  • Vowels show 3 (major) bands of formants whose energy is an enhancement of harmonics of the fundamental frequency (1st, 2nd, 3rd formant)


3 aspects of the signal l.jpg
3 aspects of the signal equal length.

The linguistic signal can be divided into three parts:

  • The fundamental frequency (intonation in many languages, tone in others)

  • The cues to the oral gestures: energy and formant structure: vowel and consonants

  • Temporal (rhythmic) structure

Big point:

Simultaneous and co-organized

analysis of these aspects


Fundamental frequency l.jpg
Fundamental Frequency equal length.

  • Intonation languages

  • Tone languages -- we’ll get to them


Cues to oral gestures formants formant changes and spread out noise l.jpg
Cues to oral gestures: equal length.formants, formant changes, and spread-out noise

  • Formants for vowels;

  • Long pauses inside of stops, followed by rapid formant transitions to the following vowel

  • Spread out regions of noise for fricatives

    How do we do this? -- recognizing as many as 10 consecutive “objects” per second!


Rhythm and timing l.jpg
Rhythm and timing equal length.

  • Japanese: based on moras. A mora is:

  • a CV: ka zo ku ‘family’ wa ta shi ‘I’

  • the V in CVV: ko-o-ko-o ‘high school’

  • N at end of syllable: o-ba-a-sa-n ‘grandmother’

  • C at end of syllable: cho - t - to ‘a little’

    The length of individual moras varies greatly in duration. BUT -- the length of an entire word varies linearly with the number of moras!


Slide28 l.jpg

English Syllables equal length.

Japanese Moras


Thinking about speech like vision l.jpg
Thinking about speech like vision… equal length.

  • Low-level feature detectors and their kin (edge detectors, orientation detectors, movement detectors: features, rhythm)

  • Identification of a signal as a piece of language X (this is a tall 3 dimensional object)

  • Identification of the object (John; the word “spinach”)


Laryngeal pitch versus oral gestures which is faster l.jpg
Laryngeal (pitch) versus oral gestures: which is “faster”?

Determining pitch could mean doing a Fourier transform and looking for peaks in the 50-300 range; or it could be done by sensitivity to resonances inside the cochlea (low level dedicated hardware!)

But the length of time over which a piece of tone is stretched tends to be longer than a single phoneme.


2 phonology l.jpg

2 Phonology “faster”?


Main points l.jpg
Main points “faster”?

  • Phonology of a language imposes highly, tightly structured organization.

  • Languages differ greatly from one another, but there are many deep generalizations relating them. (That is, the range of possible phonologies is large; but the range is also much smaller than it might be logically.)

  • The main principle to bear in mind is simultaneous signals and simultaneous constraints.


Sounds and sound inventories l.jpg
Sounds and sound inventories “faster”?

  • 1. The phonemic principle in languages

  • 2. Categorization into vowels and consonants

  • 3. More refined analysis along sonority hierarchy

  • 4. Strong universal (anthropophonic) tendencies in selection of vowel and consonant inventories

  • 5. Strong symmetry tendencies: which means that sounds are composed of parts...


1 the phonemic principle l.jpg
1. The phonemic principle “faster”?

  • Humans perceive sound chunks (“phonemes”) in discrete categories; hence ability to discriminate between exemplars is extremely good at the boundary between phonemes, and poor for within-category cases.


Example l.jpg
Example “faster”?

  • Difference between /b/ and /p/ is voicing, realized phonetically as Voice-Onset Time

“voiced”

“voiceless”

Voice Onset Time:

length of time between

opening the mouth and the

onset of vocal fold

vibrations

50 msec


Each language has its own inventory of phonemes l.jpg
Each language has its own inventory of phonemes “faster”?

  • English distinguishes /b/ from /v/

  • Spanish does not


3 sonority hierarchy l.jpg
3. Sonority hierarchy “faster”?

  • Vowels a > i, u

  • Liquids: l, r

  • Nasals: n, m , N (ng)

  • Fricatives: s, f, v, z, th, …h

  • Affricates: ch, j

  • Stops: b,d,g…p,t,k

SONORANTS

OBSTRUENTS


Slide38 l.jpg
Sonority plays a very important role in determining what sequences of sounds are permissible in a language

  • It’s not the case that a word is just a sequence of sounds permitted in a language.

  • The set of permissible sequences is much smaller than the set of imaginable sequences...


Syllables l.jpg
Syllables sequences of sounds are permissible in a language

  • Words are sequences of permissible syllables, and in general,

  • Syllables are waves of sonority:

decreasing sonority

increasing

sonority

peak: the vowel


Slide40 l.jpg

Syllables sequences of sounds are permissible in a language

  • The most basic syllable structure: CV

  • Most languages put very heavy restrictions on what consonants can appear after the vowel, in the coda:

S

rhyme

onset

coda

nucleus

h e l p


English syllable l.jpg
English syllable sequences of sounds are permissible in a language

b l a c k is OK, but

l b a c k:

l b a ck

Not a permissible sonority sequence


Slide42 l.jpg

b u m p is OK, sequences of sounds are permissible in a language

but

b u p m is not.

b u p m


Tashlhiyt berber l.jpg
Tashlhiyt Berber sequences of sounds are permissible in a language

…allows any sequence of phonemes, and divides the sequence up into waves of 2 and 3 letters based on inherent sonority

t r g l+ t >> t R . g L t ‘you locked’

t r g l + a s >> t R g . l A s ‘you locked him’

i + l d i >> i l . d i ‘he pulled’

t + l d i >> t L . d i ‘she pulled’

t l w a t >> t L . w a t


Competition for sonority l.jpg
Competition for sonority... sequences of sounds are permissible in a language

All phonemes must be organized into syllables;

an segment will ‘capture’ a less sonorous segment on its immediate left.


Limitations on the syllable l.jpg
Limitations on the syllable sequences of sounds are permissible in a language

Many languages permit no more than three items in a syllable:

Consonant + Vowel + 1 thing

  • C V

  • C V V

  • C V C


They will kill delete to achieve that restriction l.jpg
They will kill (delete) to achieve that restriction…. sequences of sounds are permissible in a language

Yokuts passive verb:

Future (nit) Aorist (it)

maxnit maxit (max)

tannit taanit (taan)

taan + nit >> tan.nit

panaanit panat (panaa)

panaa + it >> panat


4 functional orientation l.jpg
4. Functional orientation… sequences of sounds are permissible in a language

Bjorn Lindblom (for example):

  • suggests that the inventory of vowels selected is done to maximize discriminability (or a more complex objective measure, such as maximize discriminability but pay a tax on complexity [difficulty] of action).


Again l.jpg
Again... sequences of sounds are permissible in a language

  • Basic sounds (present in babble stage, perhaps): p t k m n i e a o u

  • Elaborated: add one complex gesture: clicks, ejectives, impoloseives, more vowel features like nasalization, aspiration, palatalizaiton, creaky voice

  • Complex systems: add two or more complexities to permissible combinations


Slide49 l.jpg

Strong symmetry tendencies... sequences of sounds are permissible in a language


5 symmetries l.jpg
5. Symmetries sequences of sounds are permissible in a language

Inventories of sounds in language are strong symmetric: which means we’re far more likely to find a system:

p t k

b d g

m n ng

than

p k

b d

m ng


Slide51 l.jpg
Why? sequences of sounds are permissible in a language

  • Because sound inventories are really made up of smaller gestural pieces, and inventories are statements of permissible combinatorics. Symmetry follows from that (is that clear?).


Fundamental domains of phonology l.jpg
Fundamental domains of phonology sequences of sounds are permissible in a language

  • Theory of gestures (actions)

  • Theory of rhythm

  • Theory of information (contrasts, redundancies)

  • Theory of audition: not much here


Prime effect synchronization l.jpg
Prime effect: sequences of sounds are permissible in a languagesynchronization

  • Speech is not the linear concatenation of atomic units (phonemes);

  • It is the organization over time of units on a large number (~15) of independent tiers

  • Just like the production of an orchestra: each instrument’s production is autonomous vis-à-vis the other instruments...


Orchestral score l.jpg
Orchestral score sequences of sounds are permissible in a language

  • One instrument may be silent for a while;

  • Another may play 2 notes over the same period that a third plays only 1 note;

  • But all the instruments are locked onto a over-all guidance metronome-- the conductor’s baton


Pin pin l.jpg
“pin” [pIn] sequences of sounds are permissible in a language

  • A labial gesture aligned with glottal widening;

  • A rise of the tongue body combined with a narrowing of the glottis, leading eventually to spontaneous vibration of the vocal folds

  • a raising of the tongue to the top of the mouth together with a drop of the velum to permit air to flow throught the nose.


Let s focus on tone l.jpg
Let’s focus on tone sequences of sounds are permissible in a language

  • First, a simple system like that of English!

  • English assigns a tonal melody such as HL or LH to certain specific syllables.

  • This melody is then stretched out or squeezed into the time available, given the syllables of the utterance...


Question versus statement l.jpg
Question versus statement sequences of sounds are permissible in a language

  • Did you go to the store?

I went to the store yesterday.

I went to the store yesterday.


But wh questions are different l.jpg
But wh-questions are different: sequences of sounds are permissible in a language

  • When did you go to the store?

When did you go to the store?


Hence l.jpg
Hence: sequences of sounds are permissible in a language

  • The High-Low melody is a “thing” in itself -- an intonational melody -- but to understand the sentence, you must know how it lines up with the words.

  • Tone and words: separate, autonomous, interbraided. Good word: symplectic structure.


Tone languages l.jpg
Tone languages sequences of sounds are permissible in a language

  • Q: Why look at something so exotic?

  • Answer: because it’s not exotic. More languages are tone languages than aren’t.

  • Tone languages provide us with intricate details of how the brain can organize parallel streams of linguistic information.

    *But in the words to, tonight, today, tomorrow, the toacts as if it were linked to the preceding word.


Generalization l.jpg
Generalization sequences of sounds are permissible in a language

  • English permits phonemes to belong simultaneously to two syllables ( = be ambisyllabic) under certain conditions.

  • Ambisyllabic t's convert to flaps.

    Generally speaking:

    Within a word:

  • C becomes part of syllable with a following onset ("maximize syllable onset"):

  • Has a morphology most similar to that of the other Germanic languages; and Germanic languages are similar to other Indo-European languages.

  • A small number of prefixes, quite a few suffixes.

Inflectional and derivational morphology morphemes

I sing, you sing, he sings, we sang; all different inflectional forms of the same lexemesing. Different forms are required in different contexts (syntactic contexts, we say).

  • I read; I am a reader. You out-wit me. You're a mind-reader.

    derivational morphology: creates new lexemes.


Slide88 l.jpg

  • That's one morphemesfunctional dimension along which morphemes differ; they also differ with regard to the effects they have on the stem to which they attach.

  • Some affixes leave the base unchanged, while in other cases, the base + affix is modified so as to better satisfy the phonotactics (=well-formedness conditions, high-frequency patterns) of monomorphemic lexemes.


Slide89 l.jpg

Two layers of morphology in English morphemes

Layer 1: causes change in stress pattern, vowel-shortening, vowel-deletion, c->s;

Layer 2: little change in the base.
