It looks like La pronunciation française pour de vraie
is difficult to find nowadays, which is a shame because it's quite good. I bought a copy from Amazon about 5 years ago, but as it is all in French it requires a basic understanding of the language, so I left it on the shelf. I pulled it out near the beginning of the last Super Challenge and did the first few lessons. I found the lessons interesting, but it was clear the course was designed to be a CD-ROM (in an age when CD-ROMs were all but gone), and so some things did not work the way Penny Sewell said they would in the videos. One thing that I found surprising is that it begins with rhythm rather than pronunciation, but especially for understanding natural speech in French that is actually a useful place to start. I intend to pick it up again during the upcoming Super Challenge.
I am currently working on spelling by doing dictations using French Without Toil (the old Assimil course). I've been learning French for a good 7-8 years now, but I recently realized that when I try to write I make loads of errors on basic things. For example, I might write "tu habite" instead of "tu habites" because they're both pronounced the same way. Dictation is a good way to develop both your listening skills and your spelling.
