Articulatory process

  1. 1. Some others theories inPhonetic and PhonologyArticulatory Process
  2. 2. Assimilation a phonological process in which a speech sound changes and becomes more like or identical to another sound that precedes or follows it. For example, in English the negative PREFIX appears as im- before words beginning with a bilabial stop (e.g. possible:impossible) but as in- before words beginning with an alveolar stop (e.g. tolerant:intolerant).
  3. 3. Kinds of assimilation Regressive assimilation Assimilation in which a following sound brings about a change in a preceding one For example, the rounding of the lips during /s/ in swim is due to the anticipation of the lip action required for /w/. Progressive assimilation Assimilation in which a preceding sound brings about a change in a following one For example, the difference between the /s/ in words like cats and the /z/ in dogs and the difference between the final /t/ in dropped and the final /d/ in praised are examples of progressive assimilation because the final sound (/s/ or /z/, /t/ or /d/) depends on whether the preceding consonant is voiced or not.
  4. 4. Dissimilation The opposite of assimilation, result in two sounds becoming less alike in articulatory or acoustic terms. The resulting sequence of sounds is easier to articulate and distinguish. For example: fifth /fifθs/ – (fts) sixth - sixt surprise - supprise
  5. 5. Deletion A process that removes a segment from certain phonetic contexts. deletion occurs in everyday rapid speech in many languages. in English, a schwa (ə) is often deleted when the next vowel in the word is stressed. e.g. deletion of (ə) in English Slow Speech Rapid Speech [pəréɪd] [pŗéɪd] parade [səpəˊʊz] [spəˊʊz] suppose
  6. 6. Epenthesis  A process that inserts a syllabic or non-syllabic segment within an existing string of segment. for example:word Non-Epenthesis Pr Epenthesis PronSomething [sʌmθɪŋ] [sʌmpθɪŋ]Warmth [wɔ:mθ] [wɔ:mpθ]Tenth [tenθ] [tentθ]
  7. 7. Metathesis A process that recorders a sequence of segment. Metathesis often results in a sequence of phones that is easier to articulate. for example: prescribe – perscribe. spaghetti – pesghetti.
