Articulation therapy; focusing on (er) in "bird"
You can use both the placement display and the green sound display.
Sometimes the green sound waves help clients focus on the manner of their speech by watching it. You can show them to watch for accurate consistent speech forms by making each word shaped the same.
You can also show them how they might make adjustments in their speech, by not adding intrusive sounds, or approaching their word incorrectly. For example, in this clip the child wants to approach the word "b, o, r, d" versus "b, er, d."
