New!  The complete The Entire World of R 21 Deck Playing Card System on CD-ROM! 

420 practice words separated into the 21 types of /r/. Twenty words for each type of vocalic /r/ and word position. Great for take-home practice or when working with groups. Each practice word has an auditory model (by clicking on the word) for a correct production example.
  
Included is an on-screen screening assessment for all 21 types of vocalic /r/. A printable screening form for instructor scoring is enabled.

For additional practice two games are included: Tic-Tac-Toe and Matching.  Each game reinforces practice target words by /r/ phoneme and word position.  Runs on Windows and Mac (classic & OSX)

Note: This software is designed for on screen use only.  The cards are not printable.
