A compendium of Esperanto sounds
Compiled by Don Harlow, and adapted for the 'Esperanto Viva!' course.
Note that of the 28 letters in the Esperanto alphabet, six have supersigns. Five of these have a circumflex above them; these are shown here by Cx, Gx, Hx, Jx and Sx. One has a brev above it; this is shown here by Ux. These are shown in the Latin-3 version of this page, if you can display Latin-3 characters. If not, an option is given in the contents of the 'Esperanto Viva!' course.
The following are examples of the sounds in Esperanto. These are .AU files sampled at 8 kHz sampling rate -- hence the relatively poor quality, particularly in sibilant sounds (frequencies above 4 kHz will be garbled).
There are six diphthongs in Esperanto. These are formed by a vowel
followed by a semivowel ('j' or 'ux'), not by two vowels together, which
are to be clearly pronounced as two separate vowels. Americans should have
little trouble with these, since what we call 'long vowels' in this country
are often diphthongs similar to some of those in Esperanto. Here are examples of the six diphthongs:
Remember that the accent in every Esperanto word (of more than one vowel) falls on the next-to-last vowel.
