linguistics
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

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.

Bear in mind...

English

…that English is an outlier among languages...

almost all of the volume

of a hypersphere becomes

arbitrarily close

to the skin, as the

dimensionality increases – so to speak)

Language

slide5
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.

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.

some false statements about speech
Some false statements about speech
  • The speech stream can be divided into words on the basis of short pauses between words.
  • Words can be analyzed as a sequence of phones of roughly equal length.
  • Words can be analyzed as a sequence of syllables of roughly equal length.
  • Words (syllables) have the same duration regardless of their context.
  • Words of two syllables are longer than words of one syllable.

language is fast
Language is 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?

but what is language
But what 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 phonetics1
1. Phonetics
  • 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).
vowels
Vowels
  • 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
Vowels, crudely…
  • 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
Consonants
  • 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
Spectral character of sounds
  • 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
3 aspects of the signal

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
Fundamental Frequency
  • Intonation languages
  • Tone languages -- we’ll get to them
cues to oral gestures formants formant changes and spread out noise
Cues to oral gestures: 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

We recognize as many as 10 consecutive “objects” per second!

rhythm and timing
Rhythm and timing
  • Japanese: based on moras (‘haku’ in Japanese )
  • A mora is:
  • a CV: ka zo ku ‘family’ wa ta shi ‘I’
  • the V in CVV: ko-o-ko-o ‘high school’
  • ŋ 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!

main points
Main points
  • Phonology of a language imposes highly and 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
Sounds and sound inventories

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
1. The phonemic principle
  • 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
Example
  • Difference between /b/ and /p/ is voicing, realized phonetically as Voice-Onset Time

  • English distinguishes /b/ from /v/
  • Spanish does not
3 sonority hierarchy
3. Sonority hierarchy
  • Vowels a > i, u
  • Liquids: l, r
  • Nasals: n, m , ŋ (angma)
  • Fricatives: s, f, v, z, θ, …h
  • Affricates: č [US], ʤ [IPA]
  • Stops: b,d,g…p,t,k

SONORANTS

OBSTRUENTS

slide34
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
Syllables
  • Words are sequences of permissible syllables, and in general,
  • Syllables are waves of sonority:

decreasing sonority

increasing

sonority

peak: the vowel

slide36

Syllables

  • The most basic syllable structure: CV
  • Most languages put very heavy restrictions on what consonants can appear after the vowel, in the coda:

s = syllable

rhyme

onset

competition for sonority
Competition for sonority...

All phonemes must be organized into syllables;

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

limitations on the syllable
Limitations on the syllable

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

Consonant + Vowel + 1 thing

  • C V
  • C V V
  • C V C
fundamental domains of phonology
Fundamental domains of phonology
  • Theory of gestures (actions)
  • Theory of rhythm
  • Theory of information (contrasts, redundancies)
  • Theory of audition: not much here
prime effect synchronization
Prime effect: synchronization
  • 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
Orchestral score
  • 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
“pin” [pIn]
  • 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 through the nose.
let s focus on tone
Let’s focus on tone
  • 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
Question versus statement
  • Did you go to the store?

I went to the store yesterday.

I went to the store yesterday.

but wh questions are different
But wh-questions are different:
  • When did you go to the store?

When did you go to the store?

hence
Hence:
  • 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.
flap d in american english
Flap (D) in American English

We find the flap of water (wa[D]er) under these conditions strictly inside a word:

but across words
But across words:
  • Word initial t never flaps, regardless of stresses before or after*; eat my tomato, see Topeka...
  • Word-final t followed by a vowel-initial wordnormally does flap, regardless of stresses before or after. at all, sit on it...

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

generalization
Generalization
  • 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"):
this also applies across words in english and in many languages but not e g in german
This also applies across words --in English, and in many languages, but not (e.g.) in German

classic distinctions in morphology
Classic distinctions in morphology:

Analytic (isolating) languages:

  • no morphology of derivational or inflectional sort.

Synthetic (inflecting) languages:

  • Agglutinative: 1 function per morpheme, clear divisions between morphemes
  • Fusional: more than 1 function per morpheme, and/or segmentation into morphemes is uncertain

Morphology

The internal structure of words:

  • phonological characteristics
  • interaction with syntax
most words in most languages are composed of several morphemes
Most words in most languages are composed of several morphemes
  • A verb from Tonga (Bantu):

tu - la - ba - bon – a

english
English
  • 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
Inflectional and derivational morphology

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).

Derivational morphology:

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

derivational morphology: creates new lexemes.

slide66
That's one functional 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.
slide67

Two layers of morphology in English

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

Layer 2: little change in the base.
