Cepstral Allison Voice Starter Kit

Cepstral Allison Voice Starter Kit includes both the Cepstral Allison text-to-speech voice engine license and one concurrent port license into one easy-to-use bundle.

With only one activation key required, you get everything you need in one port or channel to give your Asterisk installation a familiar voice.

*The Cepstral installation for Asterisk is designed and licensed specifically to add text-to-speech capabilities to the Asterisk telephony engine. Cepstral systems installed using Asterisk are not capable of outputting speech to files or other non-Asterisk destinations. If your requirements include non-Asterisk output of Cepstral speech, you will need to acquire a separate license directly from Cepstral. For information on a Cepstral Linux license, see: http://www.cepstral.com

Cepstral Port License

In larger applications, you may find that you need more concurrent ports to avoid delays, as your system waits for an available port to become free.

The Cepstral port license allows you to add additional concurrent ports of the same voice. These port licenses do not include a voice, which must be purchased separately.

Cepstral Allison Voice License

If you are already are a Cepstral customer with existing port licenses, and want to replace or supplement an existing voice with the Allison text-to-speech voice, you may purchase the Allison voice license separately. It will use your existing port license files.

NOTE: You must also purchase port licenses to properly use the voice. If you do not, the voice will continually ask that you purchase them, making it unusable for production applications.
