“Any recommendations for helping a delayed talker with finishing out a word – even sometimes just one syllable words? Car is “ca”. Bubble is “bu”. Sip is “si”. Do I just need to continue putting emphasis on the end of words when I speak with him?”
The fancy term for this is:
Final Consonant Deletion
It can be tricky to get a child to get a child to focus on that last sound. Like you said, I will frequently over-emphasize final consonants or syllables.
“Look at the bu-BLES! They are pre-TTY”
Often I will also touch a part of my face indicating where that last sound is made. So for a sound that is made with my lips (p, b, m) I will touch my lips to draw further attention to the sound. For a front tongue sound (t, d, n) I will open my mouth a little wider and touch just outside of my lips.
Give it a try on a few key words. Just work on those words for a week. Such as mo-M, ca-T, do-G, or other words that are very common for them.
If your child has significant difficulty with final consonant deletion, and/or is 3.5 or older, please seek an evaluation from a Speech Language Pathologist.
