I'm kinda new to this, so please excuse me if this is an obvious question. I'm trying to build a speech recognition system for a robot I'm helping on. We're planning on using Sphinx as the actual speech recognizer, then send the top ten possibilities or so over to a grammar parser (probably somewhat similar to what's going on in the Communicator project). I'm using the search_get_alt functionality of Sphinx to get the alternative hypotheses; unfortunately, none of the confidence measures seem to be set in the returned struct. In the include files, it seems that the conf variable shouldn't be set; but I would like to have values for the latden and phone_perp variables. Is there some option I need to set or something in order to make it do this, or is there some other way to deduce them? Thanks alot for the help.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
