Phonetics vs Phonology

Phonetics vs Phonology

1. Phonetics is thus concerned with sound production while phonology studies sound behaviour in realisation

   • PHONETICS
     • Phonetics is a scientific description of what speech sounds exist in a language
       • It represents
         • how they are produced and perceived and what acoustic properties they have.
           • Phonetics
             • essentially seeks to trace the processes physiologically involved in sound production
               • The major division in speech sounds is that between vowels and consonants.
                 • a vowel
                   • is a sound that is produced without any major constrictions in the vocal tract, so that there is a relatively free passage for the air
                     • consonants
                       • the airstream through the vocal tract is obstructed in some way. Consonants can be classified according to the place and manner of this obstruction
   • PHONOLOGY
     • Phonology is concerned with the regularities that govern the phonetic realisations of sounds in words of a language
       • It looks
         • at and tries to establish a system of sound distinctions relevant to a particular language
           • Phonology
             • actually delineates the functioning of sounds in particular contexts
               • we see the phoneme /t/ realised phonologically as
                 • /th/ in tape /tL/ in kettle /tN/ in kitten /to/ in other positions as in Kate
