Hugo- and Nebula-award-winning author Philip José Farmer created a highly detailed fictional language and pronunciation for his Khokarsa series (also referred to as the Ancient Opar series). In these two brief audio clips, Farmer demonstrates the pronunciation of “Hadon,” the protagonist of the novels Hadon of Ancient Opar (1974) and Flight to Opar (1976). This recording is from the Edgar Rice Burroughs Dum-Dum convention held on September 1, 1973 in Toronto, Ontario, Canada.
h: voiceless glottal fricative (expressed somewhat more strongly than in English h)
a: low central spread vowel (as in Spanish)
d: voiced dental stop
o: mid-back rounded vowel (as in Spanish)
n: voiced dental nasal
