The program uses various versions of Microsoft Speech API (SAPI); it allows to alter a voice’s parameters, including rate and pitch. The user can apply a special substitution list to improve the quality of the voice’s articulation. This feature is useful when you want to change the spelling of words. The rules for the pronunciation correction use the syntax of regular expressions.
