WHAT IS A SPEECH SOUND DISODER?
Umbrella term: problems in correctly producing speech sounds
Speech sound disorder: Phonological disorder and Articulation disorder
Back in the old days….
Our field used the terms phonological disorder and articulation disorder
What is a Articulation Disorder?
-Purely physical- just cant produce the sound.
Ex:having a lateral lisp
-Only a few sounds affected
-No patterns- we don’t know why it happens
-Child is fairly intelligible
What is a Phonological Disorder?
- Multiple sound errors
- Highly unintelligible
- Patterns of errors
- Due to underlying problem with phonological knowledge
What is the IMPORTANCE OF INTELLIGIBILITY?
- Caseloads- many children with speech sound disorders (SSDs) about 90%
- Cases more complex these days-more oral motor involvement
- Reduced intelligibility causes many academic and social problems
Even a mild disorder can have an impact….
- adults with a mild lisp judged less intelligent
- kids afraid to raise hand and talk in class
What do SSDs and language disorders do?
- they coexist
Macrae, T., & Tyler, A.A. (2014). Speech abilities in preschool children with speech sound disorder with and without co-occurring language impairment. Language, Speech, and Hearing Services in Schools, 45, 302-313.
- Compared preschool children with co-occurring SSD and language impairment (LI) to children with SSD only
- Looked at numbers and types of errors in both groups
What did Macrae and Tyler 2014 find?
-They found that children with both had more omissions (on test)
-Children with SSD and LI had more omissios of sounds than children with just SSD-they leave sounds out
Ex:cup-up
SLPs need to be most concerned about ch with …
-omissions of sounds; omissions more predictive of language/reading problems than sounds distortions
What is Phonetics?
Study of physical, physiological, and acoustic variables associated with speech sound production
What is clinical/applied phonetics?
Branch dedicated to practical application of knowledge
What is a phoneme?
Family of sounds that the listener perceives as belonging to the same category
EX: /t/
What is a allophone?
Not a distinct phoneme; allophone is a member of a particular phoneme family
EX: Tea buTTer leT characTer
What are morphemes?
Minimal units of meaning
What is a bound morpheme?
suffix or prefix that attaches to a word to alter the words meaning
What is a free morpheme?
whole word that cannot be linguistically broken down into smaller units
What are minimal pairs?
Morphemes that are similar except for one phoneme
What is Morphophonemics?
- sound alterations that result from the modification of free morphemes
- Morphophonemic rules specify how sounds are combined to form morphemes
Examples of morphophonemic rules:
If a noun ends in a voiced sound, use plural allomorph /z/ (tails, bags, pins)
If a noun ends in a voiceless sound, use plural allomorph /s/ (tarts, cops, lakes)
If a word ends in a voiceless sound, the past tense is pronounced /t/; if a word ends in a voiced sound, the past tense is pronounced /d/
With adult accent clients
What are the Suprasegmental Aspects of Speech?
- Juncture
- Rate of speech
- Intonation
What is juncture?
-Brief pauses that make up grammatical or semantic distinctions
EX: “Get the money bag!” vs. “Get the money, bag”
What is rate of speech?
- In rapid speech, decrease vowel duration
- Usually, the faster the rate, the less intelligible a person is
- Very important to address in therapy
What is intonation?
Changes in pitch contours
What is MOOSE?
- Move your lips
- Open your mouth
- Overexagerate
- Slow down
- Enunciate every sound
What are consonants?
-Produced by some narrowing or closing of the vocal tract-complete or partial closure (sh vs.p)
-Prevocalic(before vowel) - Intervocalic
Banana baNana
-Postvocalic (after vowel)
bananaS
-Initial-medial-final
What are Syllabics?
-form the nucleus of a syllable
/r,l,m,n/ ex: butter, bottle; special diacritic
What are vowels?
- Produced with an open vocal tract
1. Pure vowels (e.g., /a/, /i/, /ɪ/)- also known as monophthongs
2. Diphthongs (e.g., /oʊ/, /aɪ/, /aʊ/)- made by the quick gliding of two simple vowels so that they cannot be perceptually separated
What are Phonemic diphthongs?
-if you reduce them to pure vowels, the meaning changes ( e.g., /aɪ/, /ɔɪ/)
Pipe Pop Boil Bowl
What are Nonphonemic diphthongs?
-if you reduce them to pure vowels, the meaning doesn’t change ( e.g., /eɪ/, /oʊ/ )
What are Place-Voice-Manner?
Voicing—voiced or voiceless
Manner—how sound is produced
Place—where sound is produced
What are the tongue positions?
- Tongue height
2. Tongue advancement
What are the lip roundings?
- Rounded
2. Unrounded
tongue positions and roundings are crucial to who?
These are crucial with adult accents
