Balabolka is a Text-To-Speech (TTS) program. All computer voices installed on your system are available to Balabolka. The on-screen text can be saved as a WAV or MP3 file. The program can read the clipboard content, view the text from DOC, RTF, PDF and HTML files, customize font and background colour, control reading from the system tray or by the global hotkeys.

Balabolka 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 VBScript.
