"wav" is one format of audio that has been (recorded and) digitized to create computer compatible files. There are many flavors of sampling rates and bit depths as well as stereo and mono. For most lipSyncing uses, you can get by with 8kHz, 16-bit, mono files. Do not use 8-bit, ever, no way, no how!

You will need a program to record into and a microphone as well to create these files. I have included a link just to get you started, but I have no experience with this particular program, it was just the first free one that came up. I use very expensive, professional software that would be serious overkill for what you are asking about.

The text files are phonetically written versions of the audio file used to help the Talk Designer with its visemes. For example, there is a difference in timing (called a glottal stop) between "A nail" and An ale."
