We can study the sounds of language from the perspective of:

  • production (articulatory phonetics
  • the physical result (acoustic phonetics)
  • reception and interpretation (auditory phonetics)
slide-6
SLIDE 6

Today: [KɑnsəӚnəӚntsn̩vælz]

  • Basic articulatory phonetics

– How does the vocal tract work? – What kinds of sounds do languages use and how are they made?

  • The use of phonetic symbols

– What can you do with a phonetic alphabet? – How do you do phonetic transcription?

Speech sounds are distinguished by: voicing place of articulation manner of articulation

Noise and resonance

Air allowed to pass through an unobstructed space will resonate. Air passing through a constricted area will create turbulence. Air blocked behind a full obstruction and then released will create an explosion.

Resonants

  • Vowels [i], [u], [æ], [ʌ] …
  • Nasals [m], [n], [ƞ] …
  • Liquids [ɺ], [l], [ʎ] …
  • Glides [w], [j] …

[vælz]

  • Vowels are produced with no
  • bstruction in the vocal tract.
  • Vowel quality is determined by the

resonating cavities created above all by the configuration of the tongue and lips

slide-19
SLIDE 19

[væwəlz]

  • Vowels are categorized according to:

– Height – Frontness/backness – Lip rounding

slide-20
SLIDE 20

The vowel ‘triangle’

low high front back

Where symbols are in pairs, the one on the right is rounded

naming convention: height + front-back + rounding

e.g. [y] is a high front rounded vowel mid mid
