Regulus with Nuance 9, continued

Success, of sorts! I have a first version of the Nuance 9/server integration checked in, and Matthew tells me it runs correctly on his machine. (I don't yet have a full Nuance 9 installed here). Everything appears to do what it's supposed to: the original grammar is compiled into a Nuance 9 GrXML grammar, with the semantics transformed into string-concatenation semantics that put together a string representation of the semantic form. This is passed from the MRCP process to the dialogue server, which unpacks the strings, reconstructs the real semantic forms, and then passes them to downstream processing.

We were expecting that we'd save a non-trivial amount of time by skipping the parsing phrase in the server... but Matthew tells me that, as far as he can tell, it's slightly slower than when we were running the recogniser without semantics, and creating the semantic forms on the server side! I don't understand this at all. Will run some offline tests tomorrow and see if I can spot any obvious time-sink.
