Mommy Speech Therapy Speech Sound Development Chart
Communicating effectively with your child requires an in-depth knowledge of their language and articulation milestones. One great way to do this is by using a speech sound development chart!
Mommy Speech Therapy’s Speech Sound Development Chart is an engaging resource to explain the typical range of consonant acquisition norms. You can hang it in your office for easy reference or give parents and teachers all the info they need. Plus, there’s even a black and white version suitable for screening or assessment purposes.
This chart is based on McLeod and Crowe’s cross-linguistic review of consonant acquisition (2018), published in the American Journal of Speech-Language Pathology.
This chart summarizes the latest research on children’s English consonant acquisition and can be printed out as a poster or laminated for durability. The color chart adds an energetic and engaging element to any speech therapy room or waiting area, while the black and white version serves as great screening material or an add-on to reports.
At around this age, children should be able to produce their sounds with an accuracy rate of 80% or higher. When this is achieved, it’s time for them to progress onto the next level; you can help them practice at home and ask their SLP if needed for assistance if needed.
At this stage, they should be able to identify pictures that are familiar in rapid succession and label them with one word (e.g., “mama” or “duck”). Furthermore, they can ask for names of things with simple one-word inquiries (e.g., “What is this?”).
At the syllable level, they should be able to accurately pronounce each sound within a syllable with an accuracy rate of 80% or better. Once they achieve this feat, they are ready to progress onto connected speech levels and begin saying words.
At this level, they should be able to practice the sounds they learned at the syllable level and begin writing words and sentences. At this point, they should be able to use correct pronunciation for each letter while writing their name as well as some familiar words.
By the age of five, children should be able to correctly pronounce all vowels and produce monophthong and dipthong vowels with a 50% accuracy rate. Furthermore, the final consonant elimination process is beginning to take shape at this stage.
If you are worried about any of the above or have other concerns about your child’s speech, it’s best to consult a licensed speech-language pathologist as soon as possible. A certified SLP can determine if there are any developmental or phonological issues and provide the most suitable treatment plan to resolve them.
