Problem with Ceptral TTS & Elastix

We have runnig the Elastix 1.60 version, with de Asterik 1.4.
We can find the commands within Asterisk (we do register the cepstral with the correct steps, we try with the cepstral version: 1.6.0_2.0.27-x86_64 and with the ).
The question is if we need any other module or version to install the TTS? and then how we can install the voices?
Thanks a lot.

Maybe this link will help … l=es&tl=en
