Week 4 - The Phoneme Flashcards
Phone definition
Describing a sound in phonetic terms
Phonetic description of a language:
identifies all the phones that occur
in speaking the words of the language
Lexicon definition
lexicon here is a technical conception of dictionary, vocabulary …
Words of the lexicon can communicate diff. meanings in speech by virtue of their distinct phonetic forms:
eg [tʃɔklət] [vənɪlə] [stɹoːbɹiː]
eg [kənfjʉːʒən] confusion vs [kənfjʉːʃən] Confucian
Phonetic differences
Understand SOUND SYSTEM of a lang:
major focus = how different phones are used to distinguish different words in the lexicon of that language.
i.e. WHICH phonetic differences are sufficient to distinguish different words.
eg in [kənfjʉːʒən] confusion vs [kənfjʉːʃən] Confucian
- it is the phonetic difference between [ʃ] and [ʒ] which distinguishes
these two words of the lexicon, and their meanings.
The difference between [ʃ] and [ʒ] = significant in English.
- Not all the diffs between phones in a language are used to distinguish words of that language.
Phonetic differences in a language I
allophones
In English, the vowel in words like ‘hit’ may vary in its exact articulation
- place, duration …
- even by a single speaker
Diff vowel phones occur in diff tokens (instances) of the word.
- use IPA to transcribe them differently (to some extent)
[hɪ̘t], [hɪ̙t], [hɪt]
PHONETIC DIFFS DONT MAKE A DIFF FOR ALLOPHONES
Do these phonetic differences distinguish words in the language?
[hɪ̘t], [hɪ̙t], [hɪt]
The diff between [ɪ̘], [ɪ̙], [ɪ] does not differentiate words in English:
English doesn’t have distinct words [hɪ̘t] vs [hɪ̙t] with different
meanings.
These phonetic diffs not CONTRASTIVE in English
(contrastive is a technical term, not just another way of saying that they are different sounds.)
Phoneme definition
- a set/group of phones in a particular language, in which the differences between them are not used to distinguish words in that language
- In English, the phones [ɪ̘] [ɪ̙] etc are members of the same phoneme.
Allophone
In English, the phones [ɪ̘] [ɪ̙] etc are ALLOPHONES of the same phoneme.
(non-contrastive)
A useful comparison: phone vs allophone is parallel to female vs daughter
- female and daughter may refer to the same entity, but daughter additionally expresses its relationship to other entities
Phoneme Symbols
The phoneme can be assigned an IPA symbol which suggests GENERAL RANGE of PHONETIC PROPERTIES of its allophone
- [ɪ̘], [ɪ̙] etc. are allophones of the /ɪ/ phoneme
BRACKETS:
SQUARE brackets indicate PHONES: [ɪ̘]
SLASH brackets indicate PHONEMES: /ɪ/
phoneme corresponds reasonably well with native speakers’ sense that there is the ‘same sound’ BUT FUNDAMENTALLY NOT A MATTER OF SPEAKERS IMPRESSIONS
Phonetic differences in a language II
contrastive phones
Other phonetic differences in a language do distinguish different words.
- MINIMAL PAIRS
It’s just the difference between [b] and [p] that encodes the differences between two different words and their meanings (pat + bat)
Since the two phones signal a difference in word-meaning in the language – ie they distinguish diff words - the phones CONTRAST in this language, or they are CONTRASTIVE
hence, [p], [b] NOT ALLOPHONES OF THE SAME PHONEME IN ENG
distinct phonemes
Not allophones of the SAME phoneme.
In english:
/b/ phoneme & /p/ phoneme
This is how phoneme concept expresses the phenomenon of contrast.
Individual phones in a language are always allophones of a phoneme
[b] and [p] are allophones of different phonemes in English.
We can say that there is in English,
- a /b/ phoneme with the allophone [b] and others
- a /p/ phoneme with the allophone [p] and others.
Minimal pair
clearest evidence that the difference between two phones signals a
difference in word-meaning in a language is:
A pair/triple/set of words that:
- differ in one phone only
- differ in word-meaning
eg [bæt] and [pæt]
SIMPLEST CASE:
Pair of distinct words w distinct meanings that are minimally-different in phonetic terms
LANGUAGES DIFFER:
[b] and [p] in Arrente
p] and [b] in Arrernte
BUT diff between them not used to encode differences in meaning
- roughly-speaking interchangeable
eg ‘firestick’ [ɐləpɐ] ~ [ɐləbɐ]
There is no pair of words where the only difference is [p] vs [b].
Arrente has phoneme /p/ - range of allophones, mostly minor variants of voiceless [p] and [b]
Identifying phonemes expresses the distinction between:
Phonetic differences which ARE used to distinguish different words in a language,
and
Phonetic differences which ARE NOT used to distinguish different words in that language.
