Phonemics The Study of Phonemes
Definition of Phoneme A minimal class of phones which possess shared features that clearly contrast to those of other phonemes and form the basis of distinguishing one utterance from another.
Most Languages have 50 or fewer phonemes. No language uses all possible phonemes The phones contained in corresponding phonenemes in different languages may vary significantly.
Phonemic Categories Differ from One Language to Another In English, trilled and untrilled rs are in the same phoneme. In English b and v are in different phonemes. berry vs. very In English r and l anre in different phonemes river vs. liver In Spanish, trilled and untrilled rs are in different phonemes. pero vs. perro In Spanish, b and v are in the same phoneme. In Chinese r and l are in the same phoneme
Allophones Definition: Phones that occupy the same phoneme are called allophones.
Goals of a Phonemic Analysis 1. To identify a minimal set of phonemes for the language 2.To identify which phones from the language are classified together in a given phoneme as allophones 3.To identify the contexts in which a given allophone will be used instead of others in the same phoneme
Kinds of Allophones Free variation allophones Complementary distribution allophones
Free Variation Allophones Where the use of a particular allophone overlaps with the use of others Two sounds are used indiscriminately in different phonetic contexts
Complementary Distribution Allophones Two allophones are in complementary distribution if the contexts in which they appear do not overlap. Two sounds are never used in the same phonetic context.
Kinds of Phonetic Context Some Examples Immediate context = the sounds which immediately precede and follow the allophone The stress of the sounds that follow or precede the allophone Whether the allophone begins or ends a word When the allophone begins a word, the sound with which the word preceding the allophone ends When the allophone ends a word, the sound with which the word following the allophone begins
Immediate Context Example She vs. Shoe The vowel following the sh sound changes the way the sound is made. The two sh sounds are allophones of the same phoneme, but are used in different contexts, one following the oo and one following the ee sound.
