Acoustic descriptions of the realizations of the French sound represented by the letter “rˮ (canonically the voiced uvular fricative [ʁ]) show a relative regularity. Besides elisions and realizations as a uvular tap ([ʀ̆]), which are few in number, two main classes of “r”-sounds can be distinguished—one more consonantal (fricative “r”, [ʁ]) and the other more vocalic (approximant “r”, [ʁ̞]). A corpus study (1000 samples from 50 speakers) was carried out. The results showed that voiced fricatives generally appear in initial and medial positions, whereas voiced approximants appear in the final position. Realization in the intervocalic medial position and in contact with a consonant is more precisely studied; those results demonstrated that voiceless fricatives appear medially after a voiceless consonant while voiceless approximants appear medially before a voiceless consonant.
