We are excited to announce the alpha testing phase of SimVoice Copilot, a voice-controlled assistant designed to enhance your Microsoft Flight Simulator experience. Specially for those VR users but suitable for all.

What is SimVoice Copilot?

SimVoice Copilot is an innovative and simple tool that allows you to control various aspects of your flight simulator using voice commands, providing a more immersive and hands-free experience. This include almost all Simconnect events available and querying most common SimVar information. You just define what do you want to say and map it to either an event or simvar. For instance, map “Gear Down” phrase to the correspondent event and the app will execute the command then replying with a PC voice confirming the execution. Or you can say “Check Speed” and the app will talk back with the indicated air speed at the time.

Who can participate?

  • Users of Microsoft Flight Simulator 2020 or 2024
  • VR users and/or those who want to ease cockpit workload
  • Enthusiasts willing to provide detailed feedback

Why participate?

  • Gain early and free access to this handy tool.
  • Influence the development of SimVoice Copilot with your insights
  • Collaborate with a community of flight simulation enthusiasts

Voice recognition has advanced a lot in the years, and the app recognition rate is very, very high. There is no need of training anything, just install, configure some commands, or use the provided ones, start any flight and speak your desired command… Good pronunciation isn’t required too.

I looked through the sim variables and didn’t see one that you could use to toggle VR mode. I have used voice attack in the past and that one was easy since you just had it do the key bindings.

Sadly, there’s no such variable or command in MSFS SDK to enable or disable VR mode through SimConnect. I’m working now on trying to send keyboard inputs through the app but no luck so far.

Thanks for the reply. I’m sure there’s an easy way since a couple other programs already do send keyboard inputs but there are also drawbacks to that method. I find that often keyboard combos that are bound to commands can trigger the initial key binding. If you have a command bound to let’s say Shift-C you can also trigger something bound to just the Shift key. This method of directly invoking the variables is by far the best method. Really it should be on Asobo to ensure that there are variables for all the things that can be bound to keys and buttons. It would be far easier programming on their end of things.

Hi,

This sounds very very interesting! I have registered my interest.

Well, I’ve managed to convert the voice command “vr mode toggle” into the Ctrl+TAB keyboard combination.

Off, couse if this default key combo to enable VR is changed on MSFS it will not work :neutral_face:

A new release 1.0.4.0 has been uploaded and you can get it using the originally provided download link.

Please check it out and let me know how it works.

Regards
Gonzalo

New Release Announcement!

:sparkles: New Features

:white_check_mark: Support for Parameterized Commands
SimVoice Copilot now supports voice commands that include dynamic parameters.

You can now say commands like:
“set altitude” “thirty two thousand” or “set heading bug” “two hundred fifty five”
The system will recognize the spoken number and send the correct altitude (e.g., 32000 feet) to MSFS using SimConnect.

Voice parameter parsing has been added for the most common flight events:

“AP_ALT_VAR_SET_ENGLISH”, // Autopilot Altitude (Feet)
“AP_SPD_VAR_SET”, // Autopilot Speed set (Knots)
“HEADING_BUG_SET”, // Heading bug set (Degrees)
“AP_VS_VAR_SET_ENGLISH”, // Vertical speed variable set (Feet/min)
“AP_MAX_BANK_ANGLE_SET” // Maximum bank angle set (Degrees)

This means that if you set a voice command e.g “set altitude” mapped to “AP_ALT_VAR_SET_ENGLISH” the app will wait that you then say the desired altitude number. The recognized number will be automatically parsed and sent as a parameter when the command is triggered. Eventualy more parameterized events will be added.

:lady_beetle: Bug Fixes & Improvements

Fixed a bug where saving voice commands caused the recognizer to enter an infinite loop.

Improved stability when switching between profiles or editing commands.

Fixed an issue with the + key being incorrectly marked as invalid in the key mapping grid (you can now use “+” alone to represent Shift).

Added visual cues in the command editor to highlight events that require parameters (green background with white text).

Added a help button ? to the Command Mapper and Keyboard mapping screen explaining how to use the editor effectively.

:speech_balloon: Developer Notes

Event “HEADING_BUG_SET” will now expect that you say a numeric value to set the heading bug. If you want to set heading bug to the current you must now say exactly “set current heading”

If you’re using parameterized commands:

Make sure your command phrase ends with the variable part (e.g., number).

For best recognition results, speak the number slowly and clearly.

The app will temporarily switch to a restricted vocabulary recognizer when awaiting parameter input, then return to the normal recognizer.

:airplane: SimVoice Copilot – New Alpha Release

What’s New & Improved:

  1. Vertical Speed Logic Improved:
    Activating AP_VS_VAR_SET_ENGLISH or AP_VS_VAR_SET_METRIC will now automatically trigger AP_PANEL_VS_ON for smoother autopilot interaction.
  2. SimConnect Reliability Fix:
    Resolved an issue where SimConnect events were not sent if the app was opened before launching Microsoft Flight Simulator.
  3. UI Bug Squashed:
    Fixed: When editing a parameterized command or simEvent, all events were incorrectly displayed with a green highlight. Now, only valid parameterized events are marked correctly.

New Features:

  • Expanded Parameterized Events:
    You can now map voice commands to a broader set of autopilot and flight control parameters, including:
    • AP_ALT_VAR_SET_ENGLISH — Altitude variable set (English units)
    • AP_ALT_VAR_SET_METRIC — Altitude variable set (Metric units)
    • AP_ALT_VAR_INC — Altitude variable increment
    • AP_ALT_VAR_DEC — Altitude variable decrement
    • AP_SPD_VAR_SET — Speed variable set
    • HEADING_BUG_SET — Heading bug set
    • AP_VS_VAR_SET_ENGLISH — Vertical speed variable set (English units)
    • AP_VS_VAR_SET_METRIC — Vertical speed variable set (Metric units)
    • AP_MAX_BANK_ANGLE_SET — Maximum bank angle set
    • AP_N1_REF_SET — N1 reference set
    • SET_AUTOBRAKE_CONTROL — Set autobrake control

Known Limitations:

  • The “Set Altitude” command works correctly on most aircraft with a single altitude selector (e.g., TBM 930, Pilatus PC-12).
  • Aircraft with dual altitude selectors (hundreds/thousands) may experience erratic altitude set behavior—confirmed issue on Boeing 737 Max.
  • Parameterized events currently do not work on the default Airbus by Asobo.
  • Confirmed working on the Asobo Boeing 747.

For those who are already participating just use the original provided download link, for those who want to join, please visit our website for more information, there are still a few spots available.
