SLP Minimal Pairs for iPad

Speech Therapy Apps

SLP Minimal Pairs

SLP Minimal Pairs gives Speech-Language Pathologists a mobile tool to help clients identify and correct phonological errors.  It was developed by speech-language pathologists to target phonological disorders in children, pre-Kindergarten through 6th grade.  The app includes three types of drills: Auditory Training, Contrast Drill and Target Drill. Each drill offers a choice of words within a phonological process. Word lists can be edited for each session. Students are presented with illustrations during each session and asked to say what they see.

Research and References:

Minimal pair contrast words have been used in articulation intervention for many years (Fairbanks, 1960). Minimal pairs are word pairs that differ by only one phoneme (e.g., pat and bat) and are primarily used to demonstrate to children with phonological disorders the contrast between their production and the target word. They further demonstrate that a word with a substituted phoneme forms a different word with a different meaning. Treatment using minimal pairs is based upon communication breakdown when an incorrect word is produced secondary to a substitution, thereby interrupting the activity or game until the accurate phoneme and word are produced (Weiner, 1981). Barbara Hodson’s Cycles approach to treating phonological disorders contrasts the child’s actual production with a minimal-pair word to facilitate understanding of the semantic difference between the two productions (Hodson, 2007).

What Speech-Language Pathologists say about SLP Minimal Pairs

Worked Great 
by Slp03

Cluster reduction fully worked for me (this is noted in the description).  I like that i have the most control with the app and that the kiddos cannot chage screens of pictures easily.  Plan on purchasing full app.

This app is just what I was looking for/needing!! The kids I work with LOVE it, and I love that I have control over the targets and can take data. The fast pace of the carryover phase is great and the kids love it! Love the fact that REAL words are used. It's evident that this app was not only well thought out, but developed by an SLP. Can't wait to see more apps from this developer

I have been using this app with my students.  It has excellent data recording capability and can be used with multiple students.  I particularly like that it shows the correct vs. Incorrect items for each student.  I would love to see them add place shifts (th and s, f and th, s and sh, etc.).
