From the developer:
With this program, you can make your spoken output shine. Cepstral designs, builds, and customizes high-quality voices that enable natural and clear communication. The voices are ideal in situations where natural-sounding and intelligible verbal communication is required, but where live or pre-recorded speech is costly, technologically complex or not sufficiently flexible.
