Sphinx and Asterisk


I am trying to integrate sphinx and asterisk. I am looking for real time decoding and am not sure which sphinx version to use to give me fast and accurate decoding. I was looking at this page :-


but I found the information too cluttered. If anyone has experience with this integration, please help me with the following questions:

(1) If I have a 8kHz AM for Sphinx-3, can I integrate Sphinx -3 with Asterisk with it. Has anyone achieved success with this.

(2) Is such a model for English available on web.

(3) How about PocketSphinx. I was looking around and some places indicated that I use PocketSphinx instead. Will a 16kHz model work with this? How about the accuracy and speed when compared to Sphinx-3.
