Could you, guys, help me with searching some good TTS (Text-To-Speech) tool for commercial purposes? I checked several tool, but some of them was too expensive ($5000+), such as AT&T, other - low-quality, such as FreeTTS. I need free or low-price (up to $500) application or web service to create wav or mp3 files of English words and phrase in quality suitable for education purposes.
Thanks!
P.S. Large library of ready wav or mp3 files will be also OK.
Seems, I have found service suitable for my purposes - Acapela Box. It's priced based on the number of recorded characters and allows to download voice files in good quality and use them for commercial purposes (except on Radio or TV),
