Pronunciation workshops

I'm playing with the idea of offering pronunciation workshops on the last 3-4 weeks of class next quarter. I have always wanted to do something to help the students in my class who all speak the same language or all have trouble with the same pronunciation issues. The problem has been, what do I do with the students for whom the pronunciation point is not an issue?

Well, I think I've got it. I have been taking my students to the computer lab weekly and I have them set up on work they can do independently. I sometimes use the class period to have them work on computer skills like sending emails in an easy format to follow, or searching for information about the community, but I think for the last few weeks, I would be able to work in a few very short pronunciation workshops.


Voicing:

Khmer


W vs. V

Word-final consonant blends (old, fist, cart)

/th/

I have found a website with countless lists of minimal pairs tha tcould be a good resource for developing more materials for students to work with.

Minimal Pairs for English RP: lists by John Higgens. It is RP (Received Pronunciation aka "The Queen's English") but I think it's a good place to start.



Also, my study buddy mentioned that a friend of hers is using IPA to help with learning English pronunciation faster. I looked up some websites to help her learn IPA, so here there are:
General IPA:

IPA as it relates to English:

They reference this website for comparing English pronunciation around the world:

It's probably not good for intermediate level students as they are still working on forming one recognizable pronunciation for each sound in English. However, it could be very fun for some more advanced students.
