Minimal Pair Pack is an iPad app designed to assist with speech sound discrimination and production. The Minimal Pair Pack is designed for users with developmental communication difficulties and phonological difficulties.

The app has easy to use flash card style tasks can be set up quickly for use with a range of students including adults and adolescents with dysphasia, dyslexia or dysgraphia and teachers of adult literacy. It can also be used by therapists working with children who have language and literacy needs or those working with people for whom English is a second language.

The program targets the following speech sounds in the initial position of words: p, b, m, n, t, d, k, g, f, v, s, z, dz (as in jam), j (as in yacht),
w, r, l, th, sh, ch. On starting the games you can choose which two letters/sounds to distinguish

There are two modes to the app – Discrimination and Phrase Completion

Discrimination:  This activity allows the student to listen to the sound and select the word/picture to match what they heard. The word or phrase is read aloud and then the student needs to click on the correct card. This activity is very useful for students that are having difficulties with hearing the difference in sounds. The app settings let you customise the sound effects for correct and incorrect answers and also whether words, symbols or both are displayed on the flash cards.

Phrase Completion: This activity elicits production of target sound.  The app presents the student with a short phrase, and they must select the word/picture to complete the meaning of the message. For example “Put it over : there/pear”. The students could then read out the correct phrase if you wish.


On completion of a set of questions, there is a summary results page which lists the correct/incorrect answers and the sounds that were presented. This can be emailed if you wish.

Minimal Pair app results

The Minimal Pair app costs £20.99 which does seem very expensive for an iPad app compared to other apps I have purchased for educational use. But if you do have a speech / language unit, or have a student in need of speech/language support then this would be a good investment.
