Finally - maximal phonetic contrast pairs to help speech pathologists do the most effective phonology therapy! This set contains 16 photo and vector pairs for [l] clusters and [r].
What makes them "maximal" contrasts?
- clusters are more complex than singletons
- [l] and [r] have different phonetic placement, although both are sonorants
According to Gierut's research, teaching these two sounds in contrast to each other to a child who does not have [l] clusters or [r] singletons in his/her system will provide a generalization effect to all other error sounds in the child's system.
This is the Keynote version. Also available in Powerpoint and PDF formats.
