Need to polish your sounds? Practice 5-10 words a day!
For next level practice, come up with a sentence for each word then say out it loud.
It helps to record your own words and sentences on your phone, iPad, whatever device you have, then listen to it -- take time to listen to how you talk
This is called auditory awareness. When we are aware of how we sound, we are better able to catch our speech errors and correct them.
