Here is a valuable website from the Seattle Learning Academy has loads of free exercises for students to work on their pronunciation outside of their class. Although there are paid assessments on this site which I cannot vouch for, there are plenty of free exercises and lessons to explore and use. Students will find the free lessons on sounds, stress, linking and pitch (intonation) very valuable.
The Seattle Learning Academy also have a youtube channel where they have posted pronunciation lessons.
Please note: The assessments and materials are paid downloads. The English Language Centre cannot vouch for these materials. Please take advantage of the free portions of this site.
