The "Introduction to French Phonology," produced by the Foreign Service Institute (and the United States government) is available in the public domain. Someone took the time to upload the sound files (formerly available on a set of 20 cassette tapes) to the Internet, and to scan the thick book and turn it into a PDF file.
So now, the "Introduction to French Phonology" is freely available online. Accessing this helpful curriculum is simple: it is online, it is free and it is streamlined and simple to use. Although it does not offer the fun graphics and games that other French programs offer, it does a superb job of teaching great French pronunciation!
If you prefer a more updated version of this software that is available offline, you could consider purchasing the following off Amazon.com: Foreign Service institute French Phonology Digital CD-ROM Course (Foreign Service Institute Western European Language Series) (CD-ROM).
The "Introduction to French Phonology" software is laid out in a very simple format online. There is a link to the student text. There is another link to the instructor's manual. Then, there are twenty links to the the audio files, each link labeled according to the corresponding cassette tape that the original version of the software included.
How do you use these various elements? I recommend downloading the student text and saving it to your computer's hard drive. If you wish to give yourself the tests available in the instructor's manual, you may wish to save that to your computer's hard drive as well.
Then, progress through the student text PDF file one audio file at a time. Each audio file (i.e., Tape 1.1, Tape 1.2) will take you somewhere in the half hour to forty-five minute range to complete.
Enjoy learning excellent French pronunciation with the FSI's free online resource, "Introduction to French Phonology"!
