<html><body><span style="font-family:Verdana; color:#000000; font-size:10pt;">Just to followup on Cepstral. I used Cepstral for an Asterisk project a while back. So my information may be dated. I had not considered the for this project based on quality of voices.<br><br>Pros:<br>- Cheaper than other solutions ($50/port, $30/voice)<br>- Well documented<br>- Good Support<br>- Supports MRCP<br>- Has ASP Model<br>Cons:<br>- Voices sounded a bit too digital<br>
- Limited Languages available<br>- Somewhat difficult install<br>- Lacking a wide range of tuning options<br><br><br>
