Collection Descriptive Notes:
Terbeek introduces the recordings, each of which demonstrates some phonetic features in general or those specific to a particular language.
Collection Technical Notes:
Except for Tape #14, all the tapes were recorded in the Language Lab studio between 1973 and 1976. (Note: Terbeek's linguistic course was given over several years in the '70s; the tapes he made were saved haphazardly.) WAVE files are converted to MP3s.
