    Q: The app's sounds stutter a little when it's first started
    A: The app will load all its sound files into memory when you first launch it. This can take a little time (about 20 seconds on my SSD drive immediately after starting Windows, about 4 seconds the next time I launch Crew Chief). While this is being done the app can still be launched and will work as normal but on some systems there may be some slight delays while it loads sound files that haven't yet been loaded into memory. This is normal. You'll see a message in the console when the background load is complete - something like "Took 19.39s to lazy load remaining message sounds"

    Q: Desktop/start menu CC shortcut link is broken after every CC update, how to fix this?
    A: Shortcut link created by CC installer is a special shortcut that gets invalidated when new version of CC is installed, and we don't have control over that behavior. What you could do is:
    - go to CC install location (usually C:\Program Files (x86)\Britton IT Ltd)
    - right click on CrewChievV4.exe file and select Create Shortcut
    - place/rename that shortcut to your liking. This shortcut will stay valid between CC updates.

    Q: CC does not recognize voice commands, or recognizes them rarely.
    A: The first step is making sure CC speech recognition is setup correctly. See this post if you are having difficulties: .You should see no speech recognition related error messages and "Confidence" messages in CC console output when CC tries to recognize speech. To set speech up, follow CC help instructions. One common caveat - make sure SR software bitness matches your OS (64bit most often) and locale (en-GB, en-US, en-AU, en-IN). Obviously, currently CC only recognizes commands issued in the English language.

    Once CC SR is set up correctly, you can use "Confidence" messages in the CC console to fine tune recognition. The goal is to get confidence's numeric value as high as possible. To start with, you could try asking "Can you hear me?" using various settings and see how it affects "Confidence" value.

    Here are the main ways to improve success of SR in CC:
    1. Your physical setup matters:
      • Quality of microphone affects quality of speech recognition. If you've multiple, try them to see which one brings best results.
      • Microphone volume, boost, gain settings in Windows Sound Control Panel affect quality of speech recognition. There's no one suggestion that fits all, you'll need to experiment to see which settings bring best results.
        - For Rift CV1 users, my personal observation AGC setting harms recognition
      • External noise harms recognition. Speakers, open headphones, motion rigs, all might interfere with recognition, and you might have to experiment to find best settings.

    2. You could lower "Confidence" settings in CC Preferences. There are two preferences that control that: "Minimum voice recognition confidence" and "Minimum name voice recognition confidence". By default, CC will dismiss phrases recognized with confidence below 0.5. However, if you see that phrase recognized is the right one (check console output) but confidence is frequently below 0.5, you could lower confidence value. Note that the drawback of lowering speech recognition confidence threshold is that speech might get recognized incorrectly. I am personally running confidence of 0.34.
    3. Try "Disable alternative voice commands" setting. When checked, only the first phrase out of the list of commands is added to list of recognized phrases. That reduces number recognized phrases, but also reduces chances phrase is mistaken for a wrong one.
    4. Lastly, CC allows overriding speech recognition configuration phrases. To override, copy:

      - c:\Program Files (x86)\Britton IT Ltd\CrewChiefV4\speech_recognition_config.txt
      - c:\Users\[username]\AppData\Local\CrewChiefV4\speech_recognition_conf ig.txt
      and change phrases that cause trouble to your liking.

      Note that you would need to compare those two files periodically as CC continues to evolve.

    Last note, pronunciation matters. I noticed that pronouncing commands slowly, without too much emotion or intonation works better.

    My personal configuration example that improved recognition a lot:
    - Lowered recognition Confidence to 0.2.
    - Replaced Rift's microphone with cheap web conferencing microphone. I then lowered the gain on microphone until background noise (motion rig) no longer showed in the output level of the microphone in use.
    - Enabled "Disable alternative voice commands" setting (see 3) )
    - Modified phrases that I had a lot of trouble with by overriding them (see 4) ). Example: I had "How's my fuel" constantly recognized as "How's my aero". I replaced "How's my aero" with "How's my bodywork" and that solved it.

    Q: There are too many settings in CC Preferences window, I am lost.
    A: That's why Preferences window has the Search box. Search for what you need, and it'll filter options (try everyone's favorite, "sweary"). Most of the settings apply to all the games. But, all games have game specific settings. Searching for "R3E" or "rF2" will yield settings filtered to those games. See the tooltip by hovering over Search box for full list of supported game filters.

    Q: I want to redirect CC and game sounds into separate headphones or speakers.
    Search for "nAudio" in Preferences window. Once you enable nAudio output and/or input, you will be able to choose CC output and input audio devices (sound cards).

    Also, if you are running Win10 build 1803 or later, Windows Settings app allows configuring audio input/output per app. That is preferred way of redirecting audio output, because nAudio ouput/input is not yet fully optimized.

    Q: Can't install/uninstall Crew Chief.
    A: Under the hood, Crew Chief relies on MSI to do the install/uninstall. There are many reasons why uninstall might fail, but one of the ways to diagnose is by looking into MSI logs and finding error code, then searching for solution online.

    MSI logs are located at %temp% (press Windows+R and type %temp%). Logs have names like MSIxxxxx.log. Check log file creation time to see which is/are related to your install attempt.

    One notable error is 1612, here's MS FixIt for it:
    Thanks to S3 forum user Skybird for this solution, original post here: and

    Update 1/25/21: try this
    Update 9/16/18: looks like fixit no longer supported by MS. See this article instead:

    Q: After installing the Microsoft Speech Recognition Runtime and Language packs correctly, the app shows an error: "Unable to start speech recognition. No input is supplier to this recogniser"
    A: This can be caused by a few things, but first ensure you have your microphone set as the Default 'Recording' device in the Windows Sounds control panel. One user also reported that having the Microsoft Kinect Voice Recognition software running on his PC also caused this error

    Q: Install file "could harm your device"
    A: This is because the installer is not signed (which is expensive and only generally used for commercial software). If you trust Crew Chief then follow the instructions below to install it anyway. If you don't trust Crew Chief, well you are free to download the source and build it yourself!
