The AT&T Natural VoicesT speech engine comes bundled with two US English voices, Mike and Crystal, in either 16khz or 8khz versions. You can add the Natural VoicesT engine to your purchase, or if you already have one of our products or other text to speech software you can purchase it as directed below. Additional voices and other languages are also available for separate purchase, but the Natural VoicesT engine is required for them to work. Purchasing Instructions, Audio Samples, and System Requirements for all Natural VoicesT are below. If you have any questions at all, please email us for a prompt reply.

Minimum system requirements are a 300 Mhz Processor w/ 128mb RAM and 500MB Free Disk Space (16khz versions require 1GB Free Disk Space). While on all systems the Natural VoicesT work great when reading to MP3 and WAV files, on systems with less than 256MB Natural VoicesT can have pauses when reading aloud relating to loading voices into memory.
Recommended system requirements are a 500Mhz Processor w/ 256 mb RAM and 1GB Free Disk Space.
