I have a web application that uses SAPI to do TTS. I run it on Windows Server 2003 that has MS Sam installed by default.
I understand that there are a number of 3rd party companies that sell voices. For a commercial application, which of these companies offer licenses that don't charge a lot of money? Do they have API to easily integrate with a ASP.NET app?
I really would like to add more voices to the application.
EDIT: Anymore answers? Thanks
