Kinds of phonetics

Kinds of phonetics

  • Transcribing: descriptive phonetics? transcriptional phonetics? No standard name.

  • Articulatory phonetics

  • Acoustic phonetics

  • Perceptual phonetics (Psychology)

  • Computational phonetics (CS)

Some not so happy assumptions generally made to do transcriptions

Some (not so happy) assumptions generally made to do transcriptions

  • There is a (1-dimensional) sequence of units that define or characterize the utterance – rather than 2 or more parallel streams. We think of the articulators as being a single instrument rather than as an orchestra.

  • We can slice the utterances into pieces vertically, in time, and ignore most differences in duration.

  • Sounds follow one another, and that’s it: there is no packing of them into groups.


Sounds of english

Sounds of English

Consonants: first, the stops:

  • b as in bat, sob, cubby

  • d as in date, hid, ado

  • g as in gas, lag, ragged

  • p as in pet, tap, repeat

  • t as in tap, pet, attack

  • k as in king, pick, picking

When we need to emphasize

that we are using a phonetic

transcription, we put square

brackets [b] around the symbols.

Review where we ve been

Review where we’ve been

  • We’ve listened to the sounds of “our” English, and assigned a set of symbols to them.

  • We abstracted away from pitch, loudness, and duration.

  • We hope to better understanding our language’s sounds by analyzing them as being composed of a sequence of identifiable sounds, each of which occurs frequently in words of the language.


Consonants and vowels

  • Frequently? If a sound occurs in just 2 or 3 words, we don’t take it seriously (glottal stop, velar fricative)

  • We do this against the background knowledge that the inventory of sounds in English is not necessary as human languages go: they are what they are against a much wider backdrop of possible linguistic sounds.


Consonants and vowels

  • We also attempt to physically characterize these sounds: acoustically and articulatorily. Consonants are easier to characterize articulatorily, vowels acoustically.

  • We are particularly interested in those ways in which the English of Speaker 1 is different from the English of Speaker 2: again, working against the background knowledge of variation.


Consonants and vowels

  • We also characterize differences of sounds across sound contexts: we say, notice the different sound that occurs in front of a voiceless consonant in height.

  • Looking ahead to phonology, we will attempt to get a handle on variation in sounds in two ways:

    • Two sounds are similar if (roughly) we can characterize one of them as a variant of the other used in a particular context (“under the influence of that context,” so to speak)

    • Two sounds are distinct (hence, different) if two distinct words differ only with regard to these two sounds, in otherwise identical positions


Consonants and vowels

  • We try to characterize the inventory of sounds in a language, knowing that that language chose one set of sounds when a vast range of other possibilities might have been chosen.


Symbols

Symbols

  • We assign symbols to these sounds; in addition, we want to characterize them as best we can articulatorily and acoustically.

    Sounds can be divided into two major groups, consonants and vowels; or set along a continuum known as the sonority hierarchy:


Sonority hierarchy

Sonority hierarchy

  • Vowels

  • Glides

  • Liquids

  • Nasals

  • Obstruents:

    • Fricatives

    • Affricates

    • Stops


Consonants

Consonants

  • Consonants = obstruents + sonorants

    • Obstruents: (oral) stops, affricates, and fricatives

    • Sonorants: nasals and liquids (l,r)


Consonants have a point of articulation

Consonants have a point of articulation

The crucial points of articulation for English consonants are:

  • Labial

  • Labio-dental

  • Dental

  • Alveolar: at the alveolar ridge, behind the teeth

  • Post-alveolar/palato-alveolar/alveopalatal: multiple names for the same thing

  • Retroflex (r only)

  • Palatal (y, ñ)

  • Velar

  • Laryngeal


Consonants and vowels

Obstruents:

  • 6 stops

  • 9 fricatives

  • 2 affricates

  • Nasals (4)

  • 2 other sonorants (what are they?)

  • 2 glides


Vowels

Vowels

  • Vowels are harder to characterize articulatorily, but we try!

  • The fact that it’s harder is reflected in the fact that there is more than one way in which it’s done. IPA is one way; American is another.
