phonemes
abstract mental entities
phones
physical events
phonological rules allows
one to “translate” phonemes into actual speech sounds; knowledge of these rules forms part of the speaker’s linguistic competence
underlying form
phonemic form –> rules —> phonetic form
phonological rule has three parts:
- the sound(s) affected by the rule
- the environment where the rule applies
- the result of the rule
conditioning environment
x –> y / c__d
CE: c__d (the environment in which the rule applies)
C comes before the sound affected by the rule and D comes after it; the blank represents where the sound that is affected by the rule appears
x –> y / c__d
x becomes y when it comes after c and before d
natural class
a group of sounds in a language that share one or more articulatory or auditory property, to the exclusion of all other sounds in that language
e.g., /t, d/alveolar (oral) stop
Natural classes can be used to describe both the sounds affected by a rule and the environments where a rule applies
sibilant
segments that have a high-pitched, hissing sound quality
[s, ʃ, ʧ, z, ʒ, ʤ]
properties of natural classes
sibilant
labial
obstruents
sonorants
obstruents
produced with an obstruction of the airflow. The sounds in this category are stops, fricatives, and affricates
sonorants
segments produced with a relatively open passage for the airflow. Sonorant segments include nasals, liquids, glides, and vowels
7 types of phonological rules
assimilation
dissimilation
insertion
deletion
metathesis
strengthening
weakening
assimilation
cause a sound to become more like a neighboring sound
with respect to some phonetic property
Nasal Place Assimilation
an alveolar nasal assimilates to the place of articulation of a following consonant /n/
Palatalization (assimilation)
a special type of assimilation in which a consonant becomes like a neighboring palatal
vowel harmony (long-distance assimilation)
This typically causes all the vowels in a word to “harmonize” or agree in some property such as rounding or backness
dissimilation
two close or adjacent sounds to become less similar with respect to some property, by means of a change in one or both sounds
insertion
cause a segment not present at the phonemic level to be added to the phonetic form of a word
inserting a sound that is not supposed to be there
deletion
eliminate a sound that was present at the phonemic level. Such rules apply more frequently to unstressed syllables and in casual speech
e.g., /h/ in english
metathesis
Rules of metathesis change the order of sounds. In many instances, sounds metathesize in order to make words easier to pronounce or easier to understand
strengthening
Rules of strengthening (also called fortition) make sounds stronger.
The rule of English aspiration, as stated below, provides an example
weakening
Rules of weakening (also called lenition) cause sounds to become weaker.
The “flapping” rule of English, discussed in 3.3.1, is an example of weakening
obligatory rules
aspiration, vowel nasalization, vowel lengthening, and liquid and glide devoicing
