Learning Strategies is adding the Fast Finish to all their programs. I do not know of anyone working on that project. It is possible. I found you can use a text to speech program and then speed it up quite simply if you happen to have it in MP3 format. The windows media player controls.
That works for anything that has been recorded in MP3. I like it. Even though it adds a few minutes to listening time I feel I understand better what is being discussed. It really is something worth experimenting with however don't look to companies providing it. If you're keen create it yourself. It doesn't take much.
