Articulation is how we produce sounds with our mouth.
This involves using our teeth, lips, tongue, cheeks and vocal folds to produce clear sounds.
As children develop they are expected to have some errors in their speech. However as children become older, their speech should become easier to understand as the number of errors decrease.
