Week 3 & 4 Flashcards
What is speech?
the motor production of speech sounds using the respiratory and vocal production systems in conjunction with the articulators in order to form words and sentences
What does speech account for?
most communication challenges
By what age do most people master complex coordination activity?
8 to 10 y.o.
The largest percentage of children with speech challenges are…
boys aged 3 - 8 years old
What integrity is required for speech development?
structural and functional integrity (hearing, oral structures, etc.)
How do you master articulation re rules?
establish and learn rules regarding distinctive features or phonological rules
What else do you require to master articulation?
time for maturation and learning and an accepting environment and a model to imitate
What is a phoneme?
a mental representation of a speech sound
e.g., /p/, /i/, etc.
What is a phone?
an actual production of speech sounds in various linguistic environments
What are allophones?
sounds which are perceived by the speakers of a given language to represent the same phoneme
What is phonology?
a system and rules by which the speech sounds are organized in any given language
e.g., ngot is not English, therefore different phonology
At what age are infants sensitive to distinctions in languages?
8 to 9 months
At what age do infants lose the ability to perceive distinctive features not meaningful in language of exposure?
at about 10 months of age
What precludes perceptual development of phonemes?
developing prototypes or boundaries for each phoneme in our language
What precludes perceptual development of phonemes? re rules
develop ruels governing the acceptable phonemic combinations within own language

What are the types of speech production challenges?
Functional articulation difficulties Phonological difficulties Dyspraxias Dysarthrias Structural damage e.g., cleft palate, other trauma to articulators
What is the f type of speech production challenges?
functional articulation difficulties
e.g., lisp can be associated with brain and tongue trust (infantile swallow)
What is the p type of speech production challenges?
continue to hear all sounds and not be able to discriminate them past 10 months (Wernicke’s area)
What is the d1 type of speech production challenges?
cranial/nerve damage
What is oral dyspraxia?
NERVE damage in fibres associated with coordination problems of tongue mouth
- associated with eating problems
Apraxia of speech/verbal dyspraxia -
cranial nerve damage
Dysarthrias
muscle damages and problems with drooling if in muscles themselves, weakness or rigidity of muscles
What is the s tyep ope of speech production challenges?
structural damage
e.g., clef palate, other trauma to articulators (lost teeth, tied frenulum)
WITHOUT NERVE DAMAGE
What are phonological challenges?
difficulty with a mental reprsentation of the sound system, associated with misunderstanding of sounds
What are challenges with motor planning of speech movements?
verbal/apraxia of speech - Broca’s area damage (cortical damage)
What are examples of lower-level execution of speech production/articulation speech production problems?
dysarthrias - cranial nerve damage
strutural problems e.g. cleft palate
What connects Broca’s area with Wernicke’s area?
the arcuate fasciculus
Where is the Sylvian fissure?
divides the frontal cortex from the temporal lobe, close to Broca’s area
Where is the Rolandic fissure?
separates the frontal and parietal cortices, close to sense and motor use
What is Broca’s area associated with?
convolution (speech, expressive language, frontal lobe)
What is Wernicke’s area associated with?
hearing, auditory processing (temporal lobe)
What is the Perisylvian area?
the area in the parietal lobe associated with reading, writing, word retrieval and general integration
What area is associated with oral/verbal dyspraxias?
higher level subcortical areas, like Broca’s area
What is the most typical speech production problem?
oral/verbal dyspraxia (Broca’s area damage)
What area is associated with dysarthria?
subcortical areas like the basal ganglia and cerebellum, motor neurons to tongue, lips, soft palate and possibly subcortical areas damaged
What area is associated with phonological disorders?
Perisylvian area of the cortex
What speech production disorder is associated with trouble with articulators for eating, speaking &
dysarthrias
motor neurons from SUBCORTICAL areas
What defines the model of phonological development?
input (adult models)
phonemic representation, and
output (trying out speech)
What are underlying causes of phonological challenges?
- mid-ear problems
- inaccurate phoneme representations
ineffective organization of phonemes in larger phonological system
What is a symptom of difficulty developing expressive phonology?
intelligibility and/or speech production challenges
What is a symptom of difficulty developing phonological/phonemic awareness skills?
impacted sound-symbol relationships and reading
What is a symptom of phonological processing challenges?
difficulty recalling and repeating a sequence of phonemes/nonsense syllables or words
What is a symptom of difficulty with word learning and retrieval?
difficulty in recalling and formulating words in conversation
dysnomia - uses circumlocution due to items being on the ‘tip-of-the-tongue’, but not available
What are phonological processes of speech?
a set of rules used by people to simplify the sound system as they progress through speech development culminating in typical adult speech production (associated with speech issues if difficulties occur)
What is syllable simplification?
- final consonant deletions ca-t
- unstressed syllable deletions (ban-ana)
- cluster reduction (s-top)
What is assimilation?
repeating sounds in a word instead of saying the whole world, occurring regressively/backward (water = wa-wa) or progressively/forward (water=ta-ta)
What is substsitution?
stopping
fronting
gliding
glottalization
What is stopping?
creating a stop in a vowel that doesn’t have one
e.g., fish = pish
What is fronting?
using a consonant that is further in front of the mouth instead of the typical one
e.g., car = tar
What is gliding?
substituting a consonant for a more sonorant one
e.g., rabbit = wabbit
What is glottalization?
removing the hard t
e.g., water = wa?
What is reduced phonetic inventory?
not being able to produce a wide variety of sounds
What is phoneme collapse?
substituting phrases like “na na na” instead of actual words
What is a target-substitute relationship (“order to the disorder”)?
e.g., substitution
