Zoom with Lexi

Last Updated May 22, 2020
  1. Purchase and install LoopBeAudio (20$). (There are other choices, but just to keep it simple...)
  2. In the Sound control panel, "Playback" tab, set "Internal Playback" as your sound output device (this "loops back" the audio from Zoom and other things into a virtual input, "Internal Record")
  3. In the Sound control panel, "Recording" tab, set "Internal Record" as your recording device. (This isn't technically necessary, as you pick it in iCap Webcast, but it helps if there is a need to troubleshoot with other applications.)
  4. In the Sound control panel, "Sounds" tab, select "No Sounds" under Sound Scheme.
  5. In the "Power & Sleep" control panel, select "Never" under "When plugged in, PC goes to sleep after" (To prevent the system from going into standby during events.)
  6. In iCap Webcast, there should be a choice in the Device dropdown called "Internal Record" - select that.
  7. Assuming Company, Username, and Password are correct, and iCap Audio is checked, you should now be able to click "Connect" on iCap Webcast and begin sending the PC's audio to iCap.
  8. Launch the Zoom meeting and get the caption endpoint URI (I believe Zoom calls it a "Token") for your meeting.
  9. Define Falcon as needed to use the assigned encoder username for audio for the iCap Webcast instance.
    1. Streaming Service Provider - "Zoom"
    2. Post URL - The "Token" from your Zoom meeting.
    3. Caption Agency Name - the iCap name of the caption service Bureau. Use "EEG Lexi ASR" if using Lexi.
    4. Access Code - Your assigned Falcon access code. If you're using a human captioner, they will need to know this. It's best to stick with the same one for every meeting. If you have concurrent meetings, you will need one for each meeting.
    5. "How are you sending audio to your captioner?" - "iCap Webcast Audio"
    6. iCap Webcast Audio username - the username assigned to iCap Webcast. (This encoder must be shared with EEGASR for Lexi).
    7. "Auto-generate test captions before captioner starts?" - up to the user. I would suggest "Yes" for their first few events until they are confident in operating the system
  10. If using a human captioner: contact your caption agency and ask them to confirm audio. If the Zoom meeting hasn't started, playing a clip or a song in Windows Media Player in the ZLoopCast system will work just fine. If you want to have the captioner send an aircheck, be aware that will stop the "test" captions from Falcon as soon as they do.
  11. If using Lexi, open the Lexi Live portal on EEG Cloud, and select "Create New Lexi." The default parameters should be fine with the exception of:
    1. Access Code - Your assigned Falcon access code.
    2. Custom Model - If you've built up a custom voice recognition model, select it here.
    3. Inactivity Timeout - Given the nature of business meetings' "Soft Start," I'd recommend increasing that to at least 30 minutes.
    4. If using Lexi, don't forget to stop Lexi service in the Lexi Live portal when your meeting concludes to avoid unintended service fees.

One caveat to doing this: You need to dedicate a system to using Zoom meetings, LoopBeAudio, and iCap Webcast. That means:

  • The operator of the system cannot be a "human participant" in the meeting on that same system. Zoom gives you mix minus audio, so you'd never get yourself captioned. When we do this for our practice webinars, we would also join the meeting as a participant using cell phones, laptops or tablets so that the "ZLoopCast" box gets *ALL* human's audio.
  • The LoopCast box should have all its power saving features disabled so that it doesn't go to sleep in the middle of the event. "Presentation Mode" in power saving is usually just fine.


EEG have had some success getting the host to be a captioned participant, by selecting the host's internal mic as the input device for Webcast, but we are unsure if this is based on certain audio drivers being installed on specific PCs.


If this is a process you are interested in testing, let EEG Support know and they will generate the required Webcast download and credentials.
