I need pronunciation diagrams

[naikara]

Hello,
does anyone know any good sites that have clear pronunciation diagrams to show how the inside of the mouth looks when pronouncing. I'm teaching in Japan and the same old L and R problems keep arising and I'm finding it difficult to correct. Ls are ok but Rs are a nightmare. Help!

Welcome, naikara.

Try here: sounds of English

Here's a great tongue twister:

Lucy likes rice and Rory (a frog) likes lice.

Thank you; that was just what the doctor ordered.
