XPlane - MCE - RC4 - IXEG

*Push To Talk - PTT

PTT : "Center American three one zero with you." No response - RC4 does not hear it I can see that in the RC4 box.

PTT : "Center American three one zero with you."  Response - RC4 hears it I can see it highlights in the RC4 box.

This is my life inside of the simulator. For certain commands I always have to repeat twice.

PTT : "Approach American three one zero with you"

PTT : "Approach American three one zero with you"

OR

Similar Like "Tower or departure"

However:

"Four zero two point zero zero. American three one zero" This type of command picks up first time.

MCE first officer commands work nearly perfect first time.

Note I try many ways:
    - Hold PTT button count 1, 2, 3 - then say my respond - count 1,2,3 release PTT.
    - Voice training completed. Even created a new voice profile and completely retrained it.
    - I do have the option checked to use exact call sign checked (this is the option I most want in my communications)

Other observations - maybe will help other RC4 X-Plane users. I run the sim in full screen. I find that unless I tab out (alt/tab) of the sim at the start - before seeking clearance - and then minimize the RC4 screen most of my commands are not recognized.
Maybe that is just a placebo effect but seems to help. (I load RC4 first, then start MCE always)

Reading back clearance is always a gamble to get RC4 to actually give you "readback correct" before RC clearance quickly starts looping making it impossible to read back and you just need to use the shortcut button.

I understand that probably with most of the RC code there is nothing MCE can do to slow down RC4's speed of compliance requirements with an instruction but it would be nice. It becomes really hard to tune the radio to the next controller, and then say "Center American three one zero with you" and then have to repeat it again. Before getting scolded by the previous controller.
 Or if you try to give the full:
"Center American three one zero climbing past two three zero for two niner zero" I have yet to get that out before the previous control scolds me for not being quick enough or it gets recognized at all.
I guess it is RC hard coded on the speed of response but it get a bit frustrating.

So for now if I could just not have to repeat everything twice it would be less frustrating. 🙂

I really enjoy this plugin. The first officer is an aspect I thought I would not use but for a few things he can be really helpful. And the customizable checklist is a wonderful feature!

Thanks

Thanks for the detailed report.

Because we need to optimize speech recognition, The most frequently used requests and acknowledgments are put at the top of the speech grammar. That's why some are recognized easier that others.

Having option "Accurate call-sign required" enabled, certainly makes thing more challenging because MCE would reject a request if say you uttered "American three zero one" instead of "American three one zero".

ATC initial clearance acknowledgment is always going to be the most difficult to handle, not only because Radar Contact controllers don't give you enough time (remember it was designed for keyboard interaction", but more importantly because we can't make any assumption as to what the user is going to speak.

We could simplify it by asking users to use only this kind of reply "roger cleared to destination flight level XXX, squawk XXXX + call_sign".

In real world, pilots acknowledge all sorts of things and not necessarily in the same order. Therefore the system has to cope with variations such as

cleared to Kilo Alpha Tango Lima via flight plan route, climb 6 thousand, expect flight level XXX ten minutes after departure, squawk XXXX

copy cleared to Atlanta as filed, squawk XXXX, climb and maintain flight level, fly on runway heading,

A new MCE package for X-Plane has just been uploaded.

The speech grammar for RC4 ATC has been edited to allow "climbing past" and "climbing through" as possible variants.

Previously you would have needed to say "Center American three one zero climbing two three zero for two niner zero" or "Center American three one zero crossing two three zero for two niner zero".

There are many other variations to list here, but the point is that the word "past" wasn't expected in the grammar.

Eventually, if you have any issue with some transmission that appears to be valid ATC jargon, please report it here and we'll update the speech grammar accordingly.
