Final Exam Flashcards
Speech Sound Disorders
umbrella term to refer to disorders that may be found in
clients who have difficulty producing speech sounds
Speech sound disorders can be used interchangeably with
articulation disorders, phonological disorders
Speech sound disorders can range from
mild to profound
Mild: lisp
Profound: unintelligible speech
Speech disorders in children
idiopathic, functional
Articulation Disorders
motor based disorder, production disorder, secondary to a child’s ability to produce a sound
Phonological Disorders
rule based disorders
• reflects that the child has a lack of knowledge regarding where to use sounds that they know how to use.
• can produce the sound
• omission
• collapse in phonemic contrast, neutralization
What percent of school age children have a speech sound disorder?
5%
What percent of preschoolers have a speech sound disorder?
10-15%
will frequently co-exist with with a language disorder
Speech
consists of organized set or system of sounds that are used to convey meaning
Suprasegmentals also play a part in understanding meaning: stress, prosody
Phonemes
minimal sound elements that represent and distinguish language units
• do not have meaning themselves
Allophone
Individual variant of a phoneme
Allophonic Variation
different placements of phonemes
Morphemes
smallest • unit of meaning and made up of a combo of phonemes
• free can stand alone cannot be broken down and have the same meaning
• bound prefixes and suffixes that you add that change the meaning
Phonemic Transcription
used with slashes
• abstract description of a sound
• /s/
Phonetic Transcription
use brackets
• narrow phonetic transcription use markings
What are the four sub-systems of speech?
Respiration
Resonance
Phonation
Articulation
Respiration
Lungs, Airway, Diaphragm
Vocal folds, lungs driving force, airway
respiratory disorders: ALS, CP,
Resonance
modification of the voice as it travels through the pharynx and oral cavity and nasal cavity.
based on the modification of the size and shape of the resonating cavities
Resonatory disorder: cleft palate
Phonation
voice production that occurs when the vocal folds adduct
hyperadduction: strained strangled vocal quality
hypoadduction: breathy
Articulation
how the resonating sound is shaped and the specific speech sounds are shaped, mouth teeth, tongue, palate

Phonological Processes
syllable structure processes that modify the syllabic structure of the adult model
PP: Unstressed Syllable Deletion
or Weak syllable deletion, child omits one or more syllables in a multi-syllabic word
PP: Reduplication
totally or partially repeats a syllable in a multi-syllabic word, total or partial

add an /i/ at the end of an word, cuppy
PP: Epenthesis
insert the schwa in between two phonemes in a cluster supoon
PP: FCD
deletes the final consonant or cluster of a word bo for books
PP: Initial Consonant Deletion
omit the initial consonant or cluster of a word, ap for cop, very rare for normal developing developing children
PP: Cluster Reduction
reducing one or more sounds or phonemes of a cluster, partial or total, Partial: top for stop, total: ap for
stop. Cluster simplification: substitution of one or all of the phonemes of a cluster: det for street, wo for blue, stop liquid is reduced to a stop, liquid
with nasal or stop they will delete the liquid, s wth stop or nasal they will delete the s
PP: Stopping
stopping fricatives or affricates pat for fat
PP: Deaffrication
producing a stop or a fricative for an affricate tear for chair, dob for job
PP: Velar Fronting
replace a more front sound for a back sound. t/k, d/g, n/ng top for cop

substitution of an alveolar fricative for a palatal fricative. sell for shell
PP: Backing
very rare in normal developing children, replacing back sounds for more anterior sounds. g/d, k/t, ng/n
PP: Liquid gliding
substituting a glide for a liquid, /w/ or /j/ for a /l/ or /r/ wabbit for rabbit
PP: Vocalization
vowelzation, substitution of a vowel for a syllabic liquid or syllabic nasal
PP: Labial assimilation
a non labial consonant changes because of the influence of a labial sound in the word. bamana for
banana: b effects the n to change to a m to make it a labial-would be partial assimilation
PP: Velar Assimilation
non velar sound is changed to a velar sound because of the influence of another velar sound in the word.
krain krack for train track.
PP: Nasal Assimilation
non nasal sound changed to a nasal sound because of the influence of another nasal sound in the word.
non for nose
PP: Alveolar Assimilation
non alveolar sound is changed to an alveolar sound because of the influence of another alveolar sound
in the word. dod for dog
PP: Prevocalic Voicing
voiceless sound preceding a vowel becomes voiced. botato for potato, stops are most commonly affected
PP: Postvocalic Devoicing
voiced obstruent following a vowel becomes devoiced. pick for pig

Suprasegmentals
Stress, intonation, loudness, rate, juncture, or prosodic features
-without these, speech is difficult to understand.
Stress
- degree of effort placed of a part of an utterance and usually it is carried on the vowel of a syllable. -The stressed syllable is produced with greater intensity, longer duration, and higher pitch. -In English, stress can vary but in other languages it is fixed.
- Stress is important when you have to words spelled the same but the stress changes the meaning of the word.
Intonation
the vocal contour of an utterance. It is the way the fundamental frequency changes the way you produce an
utterance.
Loudness
The amount of intensity produced
Pitch Level
The fundamental frequency of a speaker
Juncture
the vocal punctuation. The combination of intonation and the pausing to mark distinctions in speech.
Speaking Rate:
measured in words per second or syllables per second. speaking rate varies among speakers and if you
speak at too fast of a rate, speak intelligibility is affected.
Coarticulation
-Way different phonemes as they are grouped together affect the way it is produced.
-The one sound is
influenced by another. the way as you produce sound the sounds preceding and following affect the way it is
produced, place of articulation ex: allophonic variation.
-Phonetic context helps you know why they produce it a
certain way based on the context of the word.
Aerodynamic Aspects of Speech
-have to know how air pressure, flow and volume affects speech. -Airflow builds up and
moves from greater pressure to lesser pressure. So when the vocal folds are closed the
pressure builds up under the vocal folds and the pressure builds up under the folds until the pressure builds up egressively and the air moves from the lungs to the oral cavity. voiced consonants are produced with less intraoral pressure because the vocal folds are vibrating so there is not a complete closure so there is less pressure. Children generally speak with greater
intraoral pressure than adults do. -The air supplied by the lungs is valved and modified
Egressive Air Flow
Look Up
Changes in the…
rate of airflow, its volume and its pressure results in the necessary
modifications to produce different speech sounds.
3 levels of valving:
- VF, voiced or voiceless
- Velopharyngeal mechanism
- Constrictors of oral cavity: different articulators and amount of closure they have to produce different phonemes.
3 Fundamental physical variables
- Frequency: rate of vibration, aster is higher pitch.
- Amplitude: Strength of vibration, greater the magnitude produces louder voice.
- Duration: the amount of time the vocal folds are in vibration.
Spectrum
Each phoneme has a different spectra, visual pattern of a sound.
Who has the lowest Fundamental Frequency and why?
Males due to longer vocal tract, children will have the
highest fundamental frequency.
Vowels are most intense and have low to mid frequencies and are longest in duration.
Glides and Liquids…
next intense after vowels, low to mid frequency, glides have a longer duration than liquids.
Stridents and affricates
s/z/sh/ch/dj/zh/, moderate intensity, high frequency, fricatives have a longer duration
than the affricates.
Nasals
weak intensity and short duration, vary in frequency
Nonstrident Fricatives
f/v/th/th, weak in intensity, moderate duration

babbling and first word
Infant’s auditory perception:
-Humans are able to perceive sounds when?
before birth, 16 weeks gestation. 500 Hz and 250 hz at 27
weeks 33-35 weeks can respond to 250, 500, 1000, 3000 Hz
Infant’s auditory perception:
-Not only do fetuses hear sounds but also…
perceive differences in sounds
heart rate would increase when the baby would hear their mother’s
voice
At what age can infant’s distinguish their mother’s voice?
3 days old, from a strangers voice.
show a preference for their mothers voice.
infants prefer child directed speech or motherease
first year of life: their ability to discriminate non native sounds begins to diminish
Infant Developmental Stages:
:babbling is not random but is necessary in transition to first word
Infant Developmental Stages: Reflexive Vocalizations
automatic responses, burping coughing, crying, sneezing, birth to 1 month
Infant Developmental Stages:
Non-Reflexive Vocalizations
syllabic nasals , some, voluntary vocalization, cooing, gooing, screaming, vocal play
Infant Developmental Stages:
Stage 1: Phonation Stage
produces reflexive vocalizations
Infant Developmental Stages:
Stage 2: Coo & Goo Stage
2-3 months, back vowels and back sounds like velars, begin to produce those in cv
combinations gogo gaga, primative syllable sequences because they do not have the
regular timing for syllable and consonant segments.
Infant Developmental Stages:
Stage 3: Exploration/Expansion Stage
4-6 months, vocal play increases, squeal, growl, rasberries,
bilabial trills, marginal babbling appears, cv, vc combinations,
vowels have more adult like resonance and produce more consistent
consonants with more consistent placement
Infant Developmental Stages:
Stage 4: Canonical Babbling
reduplicated babbling, 7-9 months , may sound like words but have to assess
if they have meaning, mostly stops, nasals and glides, and lax vowels start
dropping the velars and start producing more fronted sounds
Infant Developmental Stages:
Variegated Babbling Stage
stringing different cv combinations together, vowel repertoiree increases significantly
, start putting intonation in, crossover from redupicated, 10-12 months
Babbling
important milestone, will continue to babble even with first words
Conversational Babbling/Modulated Babbling/Jargon
stringing conversational cv’s together with intonation
Most prevalent Vowels
/E/, /a/, /uh/ /oo/
Most prevalent consonants
/h/, /d/, /b/, /m/, /t/, /w/, /j/, /k/, /g/, /s/, /n/, /p/
Less frequently occurring consonant-like sounds:
Affricates, fricatives, th’s, ng, /r/, /l/
Most frequently produced consonants according to place of articulation were
alvelars, labials, velars.
Most frequently produced consonants according to manner of articulation
nasals, stops
Voiced consonants occurred most…
frequently
Most predominant syllable structures
V, CV, VCV, CVCV
Are there differences between the babbling of children who are typically developing and those who have additional learning needs?
Yes, hearing impaired sounds different and is less
frequent, later fewer syllables, less likely to produce reduplicated
babbling. late talkers will babble later and produce less cannonical
babbling
Transition from babbling to meaningful speech
crossover, true words and babbling can be in the same utterance
Protowords:
Aka: vocables, phonetically consistent forms, invented words, and quasi‐words
-words that aren’t true words because they do not have a recognizable adult model but are used consistently by the infant
and meaningfully. hold meaning and usually with a gesture
Real words:
2 indicators that designate production of “true words”
- have to have a phonetic relationship to the adult word
2. have to be used consistently in a particular situation or with a particular object.
Progressive idioms (advanced forms)
actually can produce in comparison to the lack of the phonological system
Regressive idioms (frozen forms)
child’s static or unchanging pronunciation of word’s despite his/her more advanced
phonological skills. generally nicknames, habits
metathisis: switch sounds of different syllables
Development of the sound system:
-Children’s pronunciation of their first 50 words appears to be constrained
by their physiology, ambient language, and child‐specific factors
-every child is different and there is great variability.
-around the 2 birthday they are producing more words and 2 or more words and they have a larger lexical inventory
-babbling, jargon and protowords become extinguished
-words become more phonetically like the adult target
know table for consonant aquistion
Sound Acquisition
3-0: h,w,m,n,b,p,f
4-0: d.t.k.g.j.ng
6-0: l,j,ch,sh,v
8-0 to 9-0: should have all consonants and be producing the adult model
-Children’s phonetic inventory was significantly larger in the initial position early on because they produce naturally more open syllable words
Consonant Cluster Development: Studies show that by age 4-0…
s+stops
s+nasal
stop with a liquid except for gr and a stop+/w/ in the initial position
Mastery of 3‐member clusters and clusters containing a fricative member
continued until…
age 8
pg. 175 mastery of different cluster that from from 4-9
younger children are more likely to produce CR and older children will produce Cluster Simplification
Vowel Production Development
- By 18 months:
- At 2 years: all vowels and diphthongs were produced with at least 80% accuracy accept stressed and unstressed.
- By age 3-0: produced all vowels and diphthongs with 90-100% accuracy.
Common error types:

common to delete final fricatives s,z,and sh, stopping of fricatives and
affricates, devoicing of the final z and dj, depalatialization, deaffrication,
dental distortions of s, stopping of initial s
Consonant Clusters
by 2 years old a child can produce clusters they just may not be the adult model.
word final clusters are developed earlier than word initial clusters thought to be the addition of
morphemes in the final position
clusters with a stop are going to be produced earlier
two element clusters are going to be produced earlier than three
Development of Sound Classes:
Development of distinctive features from earliest to latest developing
very first to develop +nasality, +grave
(most anterior, most front), earliest to later, +voice,
+diffuse(produced in the posterior part of the oral cavity), +strident,
+continuant
Development of Sound Classes:
Phonological processes in normal developing children
every child goes through producing Phonological Processes. FCD, Cluster
Reduction, Weak Syllable Deletion, Stopping, Fronting, Gliding are all the most
common in Normal Developing children.
-Most phonological Processes are absent by age 5
Processes disappearing by age 3
FCD, WSD, Velar Fronting, Reduplication, Prevocalic Voicing and Consonant
Assimilation
Processes persisting after age 3
Cluster Reduction, Epithisis, Gliding, Vowelization or Vocalization, Stopping,
Depalatization, Final Devoicing

list of processes chart
Speech Intelligibility
By 5 years of age…
● Majority of children by first grade will have acquired the phonological
skills of their language
-Pg. 187 by 19-24 months should be 25-50% intelligible
2-3 years should be 50-75% intelligible
4-5 years should be 75-90% intelligible
5+ years 90-100% intelligible
Explanations of speech sound acquisition in children fall into 2 main groups:
- Linguistic Models: what they can produce
2. Behavioral Models: based on experimental data
Speech Screening
- generally will be pass or fail.
- can be conducted with a large number of individuals in a relatively short period of time
- If a child has a speech disorder, it means the child should go through more in-depth testing
- done in schools from preschool-1st grade, also in hospitals
- look at cognitive, speech, and language
