Inappropriate speech sound deletions and substitutions for age affecting multiple sounds.
multiple consonant or vowel errors, intelligibility below 75%
Phono deficits have academic, occupational and social consequences.
Types of Speech delay
SD-OME (otitus media with effusion)
SD-DPI (developmental psychosocial involvment)
SD-DAS (Developmental Apraxia of Speech)
Problem age-inappropriate deletion/substition errors w/academic occupation or social consequences.
Expressive lang disorder from 3-5years: 40-60%
Disorders of lang., spelling and reading after 6 years
Percent of speech delay kids at 3-5 yrs: 56%
50-60% of kids have 1 or more family members with similiar problems; 20-40% have first degree relatives affected (sibling or parents)
More males than females 3or5:1
Typically do not have deplayed start of speech.
SD-OME Otitus Media with Effusion
30% of SD children
Frequent OM; at least 6 episodes from birth to 2 years
At least 35dB threshod on 3-4 frequencies
Problem age-inappropriate deletion/substitutionerrors w/academic occupational or social consequences
Same portion of males to females
Increased risk for express lang disorder and academic difficulties
typically no delayed speech
likely highly familial
SD- GEN (Genetics)
typical phono processes profileMore relative omission errors compared to SD group as a wholeLow % of sibilant disorders compared to SD group as a wholeLow % of sibilant disorders compared to SD group as a whole
SD-OME (Otitis Media with Effusion)
backing of fricative and stops
Small intelligibility-speech gap(PCC and intelligibility very similar)
Epentheic vowels on glide consonants
Frequent glottal stops in all positions and before vowels in initial position of words.
Initial /h/ deletions, /h/ insertions on word initial vowels, /h/ initial substitutions.
