NextUp.com is proud to be the US Distributor for Acapela Groups InfoVox SAPI Text To Speech Voices.  These voices have been very popular add-ons for TextAloud, but those versions are usable only with TextAloud.  By popular demand, we are now able to make these voices available in an open, SAPI compatible version, meaning they will work with any text to speech functions on your computer including built-in windows TTS function, screen readers, and other TTS Programs.

These open versions are more expensive than the TextAloud versions, but offer high quality TTS in an open format.
