From Their Website:
At Cepstral, we design, build, and customize high-quality voices that enable natural and clear communication. Our voices are ideal where live or pre-recorded speech is costly, technologically complex or insufficiently flexible.
Robust and highly scalable, our technologies can be deployed on hand-helds, desktop and server applications. Our Text-To-Speech (TTS) engines and voices are the smallest commercial unit selection synthesis offerings in their class.
