The Pair Squares Collection

I have made 50 of these Pair Squares (minimal pairs, squared) for different phoneme contrasts in English (download the PDFs in two files below!). One person says one of the phrases, the others have to identify which one they think they heard. There are some which are really important for learners to master, both receptively and productively, in order to understand and be understood. There are others which show accent alternatives, both of which are equally valid, and these are more for building learner awareness of different varieties of English.
The images in this collection of pair squares have been generated by AI. Little by little, I’m becoming aware of the environmental impact of this kind of data-heavy technology usage. In order for these pictures to perhaps justify the ‘cost’ of their generation, I hope their benefit (if any) will be spread as widely as possible. I would therefore like to make them freely available to as many ELT teachers as can be reached. If you’re interested, please download them from here: (and if you like them, spread the word!).
Note: I made these resources as part of the online support material to accompany my new book ‘The Minimal Pair Collection’.
