Airac 2509 and speech recognition

Attagene

Hi,
Has any improvement been made on the speech recognition module in the latest airac (as this was a target goal, as stated in previous posts)?

From the most recent email sent a few minutes ago:

Hello!

We are pleased to announce that a brand new version of London Control (1.5) is now available!

Along with other changes, a significant enhancement is an upgrade to speech recognition, which has been achieved through the assistance of a third party who worked with us over the summer months. Although this has come at a cost, we are not passing these charges on to users.

We have successfully upgraded a part of the sim that had needed improvement for a long time, and we hope you will see a big difference with speech interaction.

We would welcome any feedback once you have had chance to run the new version, and thank you for continuing to support London Control - the most authentic air traffic control simulator of its kind.

Regards,
London Control

Yeah, just received the email as well, guess I posted to quickly 😃
Another question :
My latest airac is 2413, do I need to purchase the base+airac or is the airac upgrade enough to have the improved speech recognition?

Attagene I think its base+airac, but confirm with one of the admin/s. @samkidd same to you

WOW . Words cannot express my gratitude appreciation and thanks for all the hard work you do guys . speech recognition almost 90% . i guess more training would increase the accuracy more . This speech recognition accuracy reminds me with windows xp.

is it possible to train the files through the Reco tool for more accuracy .

Would you like to elaborate? How you do it? I have installed 1.5, I have UK and US language pack installed under Win11 (plus of course my native german one). Now, what else to make speech recognition work? Do I have to activate that Win11 speech access feature? I just have 0% recognition so far (in all fairness, I used LC without speech rec for decades now, do not really miss it since and just gave it a try for 30 minutes).

Sorry for being daft - but I have base + AIRA 2413 - how do i upgrade to this new version please?

max4

samkidd You need to buy the new updater since you have a year old airac (we are on 2509)

I'm getting a invalid serial number message after upgrading from 2413 to 2509. Email sent to hq@londoncontrol.com

So, I bought the latest base+airac but can't get the speech recognition to work (enventhough the English language pack is installed in Windows 11).

The program SpeechReco returns an error "SAPI : unable to load grammar"

Has anyone faced this issue and managed to solve it?
I've also sent an email to support, awaiting their answer.

Same here. There is absolute no documentation how to get the speech reco to work. So absolute useless for now.

Graham

hu277 speech recognition runs automatically upon starting v1.5 of LC, thus the lack of any specific documentation. We are not receiving blanket reports about this issue so it appears to be isolated, in which case we have referred it for further investigation and remedy. Watch this space for updates, and thanks for your patience.

Odly enough it did seem to work at first try. Nothing has changed since (i think) now the windows speech recognition app jumps on top of london control and not even a heading instruction is understood by traffic. What am i doing wrong?
After doing some testing it seems to be the fact that my computer does not hear my voice, as if the volume is too low, but all volume dials are 100%... any advice

Hello Martin,

Actually I’m using windows 10 on my PC , nothing much I did, just downloaded the new version 1.5 and it’s located in new location under program files x86, it used to be under DM aviation Limited file.

Basically I just run the simulator and the voice recognition works 100% accuracy .

What I believe Martin that your window 11 doesn’t support the voice recognition, as far as I remember Graham or someone else in support team said windows 11 still having problems in supporting LC voice recognition. And that’s why I’m ignoring the win 11 update message that appears in my screen.

Best Regards,
Raad.

Hi,
For those interested, I've managed to resolve the issue of the speechreco.exe displaying the error :
sapi : unable to load grammar.
I'm using Windows 11 and have the french, US & UK speech recognition installed. I'm using French as a display language on a daily basis (and when using LC as well).
The error message mentioned earlier basically means that windows can't load/choose the correct speech recognition version.
Inserting the following key in windows registry (paste in a txt file, rename it to .reg to load it in regedit) forces windows to use the english version of the speech recognition engine :

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Recognizers]
"DefaultTokenId"="HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Recognizers\Tokens\MS-1033-80-DESK"

Reboot after inserting the above key and you should be good to go.
I've tested tbe speech recognition during a session afterwards and as some others have said, I'm amazed at the accuracy, great job! It indeeds reminds me of the old XP days as well.
Once again, thanks for the work done, keep it up!

Graham

Attagene thanks for this invaluable info Attahene; I have also copied it to a separate forum post with an appropriate title, which may assist other users if they encounter the same issue. Thanks once again.

Hi Graham ,

Your response gives me hope that this can be happen , As I am flying into and over UK FIR , I noticed the following words used by London ATC which is i hope that's can be implemented in LC speech recognition file .

BAW1 ( HELLO , ROGER , GOOD MORNING , GOOD EVENING , OR RADAR CONTACT ), that's if its flying from sector to another sector inside LC FIR no need to mention maintain flight level 350 , EXCEPT when its coming from different FIR. so as i am accepting the traffic from inside my LC FIR I should say the call sign follows by one of those phrases above .

BAW1 ( TRAFFIC 10 , 12 OR 2 CLOCK MAINTAINING FL ... CROSSING FROM RIGHT TO LEFT , LEFT TO RIGHT or OPPOSITE DIRECTION ) , the response from the traffic will be ROGER or TRAFFIC INSIDE .

Is it possible to generate traffic that randomly can ask for higher altitude inside the sector . LC BAW1 REQUEST FL380.

lastly hopefully in the near future we will see a multiplayer system .

thank you for this great enjoyably and wonderful work especially with the recent update that include the speech recognition system which made the simulator closer to reality than before as if i am seating with a real ATC on the control screen .
.
. All the best
