Learn how to change the ATC voice or accent in a flight simulator, what each speech source allows, and why an installed voice may not appear.
Yes, but the level of control depends on the flight simulator and ATC system. Some let you switch speech engines, language packs or installed voices; others assign voices automatically and provide no accent selector. Third-party ATC can add more variety, while live online ATC uses each controller’s real voice.
What part of the ATC voice can be changed?
An ATC voice, its accent and its phraseology are separate things. Changing the speech voice may alter its pitch, gender or regional pronunciation, but it will not necessarily change the words, procedures or pronunciation dictionary used by the ATC system.
| Method | What you can change | Main limitation |
|---|---|---|
| Built-in ATC settings | Speech source, language or voice where supported | Many simulators assign controller voices automatically |
| Operating-system speech voice | Installed synthetic voices and languages | Works only when the simulator uses that speech engine |
| Third-party ATC | Potentially broader voice and accent selection | Options depend entirely on the add-on |
| Live online ATC | Real human voices and natural regional accents | You cannot choose who controls a particular position |
A common mistake we see is changing the computer’s default text-to-speech voice and expecting every simulator to follow it. Recorded ATC systems and simulators using their own cloud or bundled speech engine will ignore that setting.
How do I change the ATC voice in my simulator?
- Identify the ATC source. Establish whether you are hearing built-in ATC, a third-party ATC application, recorded mission audio or a live controller. The relevant voice setting belongs to that system, not necessarily to the simulator’s main audio menu.
- Look for speech settings. Check the simulator’s sound, ATC, accessibility and online-service options for entries such as text-to-speech, voice source, language or offline speech.
- Check available language voices. On a PC, install the required operating-system speech language only if the simulator supports local system voices. A display-language pack alone may not include a compatible speech voice.
- Restart the simulator. Many speech engines enumerate available voices when the programme starts, so a newly installed voice may not appear until a full restart.
- Test built-in and add-on ATC separately. Use a short ground frequency exchange and confirm which application is producing the sound. Third-party ATC often has its own audio device, voice and volume controls.
Which flight simulators let me select an ATC accent?
Precise accent selection is uncommon in built-in ATC, and support varies between simulator generations and platforms.
Microsoft Flight Simulator
Microsoft Flight Simulator 2020 can use Azure or Windows Offline speech, but switching between them changes the speech source rather than providing a simple controller-accent picker. Our explanation of MSFS 2020’s Azure and Windows Offline speech modes covers the practical differences.
Microsoft Flight Simulator 2024 settings and available voices can vary across PC, Xbox Series X|S and PlayStation 5. Console editions cannot use Windows speech packs installed on a PC. In either MSFS generation, the built-in system may select voices dynamically instead of honouring a requested accent.
FSX and Prepar3D
FSX uses legacy voicepack content assembled from recorded speech fragments, so changing the normal Windows text-to-speech voice does not replace its controllers. Pilot and controller voices are also handled separately. See our FSX-specific voice-setting and voicepack guidance before altering any files.
Prepar3D inherited parts of the same ATC approach, although behaviour can differ by edition and installed content. Avoid replacing core voice assets manually unless an add-on explicitly supports that simulator version; mismatched voicepack data can produce missing callsigns, silence or broken phrases.
X-Plane, DCS and other simulators
X-Plane’s speech behaviour depends on the version and operating system, with some voices generated through built-in or system speech services. DCS radio and controller speech is commonly tied to recorded mission, terrain or module assets, so an accent is usually part of that content rather than a global voice setting.
Why does an installed ATC voice not appear?
An installed voice will appear only if its speech technology, language and platform match what the simulator supports.
- Wrong speech engine: the simulator uses cloud speech, recorded samples or a different operating-system speech interface.
- Language mismatch: installing a keyboard or display language does not always install its speech component.
- Architecture or compatibility mismatch: older simulators may not recognise newer system voices.
- Automatic voice assignment: the voice is available, but the simulator chooses controllers by airport, region or session rather than exposing a selector.
- Console restrictions: Xbox and PlayStation editions cannot load arbitrary PC speech packs.
- Add-on audio ownership: a third-party ATC programme is generating the voice and ignoring the simulator’s own selection.
Will changing the voice also change ATC phraseology?
Usually not. Voice selection controls how speech sounds; the ATC logic controls clearances, sequencing, terminology and responses. A British synthetic voice can therefore still read US-style phraseology if that is what the underlying ATC system generates.
If authentic procedures matter more than a particular accent, compare the available options for improving ATC realism. Voice-recognition software is another separate layer: it changes how your transmissions are entered, not necessarily what the controller sounds like, as explained in our guide to using spoken commands with simulator ATC.
Choose the built-in speech setting when you only want a different voice source, a compatible third-party ATC system when you need explicit voice or accent choices, and live online ATC when natural human speech and regional variation matter most.
