Web Program D & Haptek Integration

Hi I am doing a web application where program D is the AIML engine and Haptek being the graphic interface. Is there a good way to integrate these 2 programs together so that the conversations will be speaked out by the haptek avatar?

I have also been trying to send user input by pressing 'enter' but it seems that the voice reply by the Haptek avatar does not sync and usually tend to delay by 1 answer or even just repeat the same answer? Is there a getaround or good solution for this? thanks.
