Phonetics Chapter 1-2

IPA

International Phonetic Alphabet- used to represent the sounds of words (not the spelling)

code point

a unique alphanumeric code

through

7 printed letters(graphemes), 3 speech sounds (phonemes), (1 morpheme)

running

7 graphemes, 6 phonemes, 2 morphemes

phonetic alphabet

an alphabet that contains a separate letter for each individual sound in a language

How many letters are in the English alphabet?

26

how many speech sounds are there in the English language?

42

Allographs

different letter sequences or patterns that represent the same sound.

Digraphs

a pair of letters that represent one sound.

morpheme

the smallest unit of language capable of carrying meaning.

free morphemes

morephemes that can stand alone and still carry meaning.

bound morphemes

bound to other words and carry no meaning when they stand alone.

mean length of utterance (MLU)

the average # of morphemes per utterance is a useful tool emplyed by SLP's in examining language behavior in children.

Phoneme

specific speech sound that can signal a difference in meaning.

diacritical markings

specialized phonetic symbol used in transcriptions to represent allophone productions (variant productions of a phoneme) as well as suprasegmental features (stress, intonation, tempo)

minimal paris or minimal contrasts

words that vary by only one phomene

allophone

member of a phoneme family that is a variation in the pronunciation of that sound.

phonetic context

certain allophones must be produced a particular way due to constraints of the other sound in a word

complementary distribution

allophone production that is tied to a particular phonetic environment

free variation

some allophones are not linked to a phonetic context and are free to vary

syllable

a basic unit of speech production and perception generally consisting of a segment of greatest acoustic energy (usually a vowel) and segments of lesser energy (usually a consonant). a unit of speech consisting of an onset and/or a rhyme.

onset

all the consonants that precede a vowel

rhyme

is divided into the nucleus and coda

coda

single consonant or consonant clusters that follow the nucleus of a syllable.
in some instances the coda may have no elements at all

nucleus

typically a vowel

open syllables

syllables that end in a vowel phoneme

closed syllables

syllables with a coda/end with a consonant phoneme

word stress/Lexical stress

the production of a syllable with increased force or muscular energy, resulting in a syllable that is perceived as being louder (intensity), longer in duration, and higher in pitch; also known as word accent.

bisyllablic words

(two syllable words) will always have one particular syllable that receives primary stress (greatest emphasis).

Multisyllabic words

(more than two syllables) may have the primary stress on the second syllable.

word class

parts of speech such as noun, verb, adjective, etc.

systematic phonemic transcription

also referred to as broad transcription, or simply phoneic transcription. There is no attempt at transcribing allophonic variation.

Systematic narrow transcription or allophonic transcription

relies on diacritics to indicate allophonic variation.

impressionistic transcription

used when nothing is known about particular speech sound system prior to analysis or with children with severe speech sound disorder.
