ZebSpeech is a FREE program, which supports Text-to-Speech (computer reads the text to you!) and speech recognition (You dictate the text to computer and it types!) technologies. You can change the speed and the pitch of the speaker. Because ZebSpeech has a different vocabulary system, it results in more accuracy. In addition ZebSpeech has an advance word-processor, which supports many useful features. For example you can edit Microsoft Word .doc files, and convert files to .pdf WITHOUT requiring any extra third-party software. Speech recognition, text-to-speech and word-processor makes ZebSpeech a unique and comprehensive software!
