Sounds Right is the British Council iPad app. It's a free interactive pronunciation chart for learners and teachers of English.
This is the new British Council phonemic chart. Help your students hear the sounds of English by clicking on the symbols below.
I often see the Sound Foundations chart (you can see it below) in classrooms, and teachers using it to bring pronunciation into the central arena of language work.
The point I want to make is that pronunciation teaching has been neglected and that we have all lost out through this.
