Hi, We are planning to set up a prototype IVR system in Urdu language using Asterisk. For speech recognition, we will be using our own engine built using Sphinx, and for text to speech synthesis (for run time generation of responses based on user queries), we have a system for Urdu built in C++ that can be used as an API. My question is, can the Linksys SPA400 telephony gateway be used with Asterisk to develop the IVR system described? And if not, what other options should we explore? We have looked into the following options: 1. The Linksys SPA400 telephony gateway: we have used this previously with Trixbox to collect speech data over a telephone line, but we are not sure if it would support an IVR system such as the one described. 2. Digium telephony cards: we may have to rule these out because of cost issues if we have other options available. Also, most of these seem to be internal cards, and we would prefer to use an external device due to some equipment related limitations. 3. Dialogic cards: these were also ruled out due to cost issues. 4. We have also looked at Asterisk documentation and it seems that an IVR system setup should be possible with any of these devices, but could find no recommendations for IVR applications in particular. Any suggestions will be much appreciated. -- Thanks & regards, Huda Sarfraz www.cle.org.pk -------------- next part -------------- An HTML attachment was scrubbed...
