Typical Speech Development
We need to understand typical speech development
in order to follow Auditory-Verbal practices.
![Page 2: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/2.jpg)
Normal speech development encompasses:
• Crying • Cooing • Laughing• Vocal Play/Babbling • Echolalia • Jargoning • Words • Articulation

From birth -3 months you can expect to see a typically developing child:
Coo and goo when content Use differentiated cries Vocalize single syllables Blow bubbles
![Page 4: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/4.jpg)
From 4-6 months you can expect to see a typically developing child:
Use vocal play when playing Use speech like babbling to self and others Babble sounds with p, b, and m (putting lips
together) Babble some double syllables Begin to use nasal sounds Make urgent noises to prompt adults to action Vocalize pleasure and displeasure Stop vocalizing when an adult enters the room Coo, cluck, gurgle, and laugh

From 7-9 months you can expect to see a typically developing child:
Babble with sounds changing to include more consonants – n,t,d,b,p,z Babble with sounds like singing Reduplicate babbling –babababa Imitate intonation and speech sounds Use vocal play with intonation patterns
![Page 6: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/6.jpg)
From 10 - 12 months you can expect to see a typically developing child:
Vocalize during play Vocalize into a mirror Use a vowel – consonant ratio of
2:1 Imitate intonation and phrase
patterns Use first words
![Page 7: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/7.jpg)
From 1 – 1 ½ years you can expect to see a typically developing child:
Use Jargon Use echolalia Omit final consonants and some initial
consonants Be unintelligible except for a few words Use words produced with CV emerge Accurately imitate some words Use twenty-one phonemes
![Page 8: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/8.jpg)
From 1 ½ - 2 years you can expect to see a typically developing child:
Use more words than jargon (usually gone by 2 years)
Ask questions by raising intonation at the end of a phrase
Improve intelligibility – 65% intelligible by 2 years
Develop words produced with CVC
![Page 9: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/9.jpg)
From 2 – 2 ½ years you can expect to see a typically developing child:
Use twenty-five different phonemes Use beginning consonants Be 70% intelligible to listeners Omit final consonants Reduce consonant blends Substitute one consonant for another Emergent use of final consonants in
words Use lower and more stable pitch
![Page 10: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/10.jpg)
From 2 ½ to 3 years you can expect to see a typically developing child:
Use some substitutions and distortion
of consonants Continue to improve intelligible
speech to 80 % Masters consonants: p,m,n,w,h
![Page 11: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/11.jpg)
From 3 – 3 ½ years you can expect to see a typically developing child:
Use final consonants most of the time No longer producing the phonological
processes: consonant assimilation, doubling, final consonant deletion, prevocalic voicing, reduplication, unstressed syllable deletion, velar fronting
Mastery of 2/3 of adult speech sounds Use speech which is 75% intelligible
![Page 12: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/12.jpg)
From 3 ½ to 4 years you can expect to see a typically developing child:
Be intelligible with connected speech Continue to refine articulation skills Master consonants: b,d,k,g,f,v Continue the phononlogical processes
after 3 years of cluster reduction, final devoicing, gliding, and stopping
![Page 13: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/13.jpg)
From 4 – 4 ½ years you can expect to see a typically developing child:
Use omissions and substitutions Be intelligible in connected speech
![Page 14: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/14.jpg)
From 4 ½ to 5 years you can expect to see a typically developing child:
Use most consonants sounds consistently and accurately,
thought not mastered in all contexts Have more errors in difficult
blends

From 5 to 6 years you can expect to see a typically developing child:
Master consonants: ng, r, l
![Page 16: Typical Speech Development We need to understand typical speech development in order to follow Auditory-Verbal practices](https://reader035.vdocuments.us/reader035/viewer/2022072006/56649cf85503460f949c885a/html5/thumbnails/16.jpg)
By knowing and understanding typical speech development, we are able to target specific developmentally appropriate speech sounds and to provide the listening opportunities to develop those sounds.
