This version of the Pronpack Sound Chart uses the symbols for the American sound system as used in Celce-Murcia, Brinton and Goodwin Teaching Pronunciation, CUP 1996. The r-coloured vowels are given as separate hexagons.
This version of the Pronpack sound chart uses typical spellings rather than phonemic symbols. Use this version if the phonemic symbols seem to be too hard for your students to take on board. You can download versions below with or without pictures, black and white or colour.
