MBROLA uses an Algorithm that is similar to Spectral Model Synthesis[1] 
to remove aperiodicity from a speech signal.
Spectral Model Synthesis has also been used in other synthesizers such 
as VOCALOID. However the algorithms of WORLD are newer.
The code is from Mage/pHTS[2] which they released under the GPLv3.
