  • SV-1 Voice Key SuperLab 5.0.5

    PLATFORM: SuperLab 5.0.5 on Mac 10.12.2 Sierra

    GOAL: I want to measure the DURATION of a vocal response

    DIFFICULTY: SuperLab does not seem to be detecting Voice Off in the SV-1


    Participant Input
    • Selected SV-1 Voice Key as Input
    • Created a VoiceOn Response
    • Created a VoiceOff Response
    • VoiceOn Response edited so that it maps onto Voice Key Pressed
    • VoiceOn Response edited so that it maps onto Voice Key Released

    • Unchecked Ignore the voice key release
    • Checked Wait until the voice key is released
    • Tried selecting each radio button in turn to see if this was the source of my problems, but it is not

    • Input: End the event after a fixed time limit
    • Input: UNchecked Delay feedback actions
    • Correct Response: Set to VoiceOn (also tried setting to VoiceOff and to both VoiceOn and VoiceOff)
    • Feedback:
      When response is VoiceOn: Start timer, Set trial's tag to VoiceOn
      When response is VoiceOff: Pause timer, Set trial's tag to VoiceOff

    I am reliably detecting the VoiceOn event, but never the VoiceOff event. This, of course, makes measuring the DURATION of the voice event impossible. Curiously, neither trial tag -- even that which I set for the detection of a VoiceOn response -- is recorded in the data file.

    To isolate the problem, I set the even parameters to present the trial until detection of a VoiceOff event. The trial never ended and I had to force-escape. This is what makes me think the problem is in detecting the voice-off event in SV-1.

    Am I missing something?

    Thanks for your time.

      Thank you for your post. It seems that there is an issue with the release of the voice key. I will document these findings and bring it up to the developers.

        Tracy, SuperLab 6 is now in beta testing. It incorporates a fix for the “SV-1 key release” issue. Let me know how the fix works for you.

        P.S. This is a beta release with extensive under-the-hood changes. So there might be other bugs.

          SuperLab 6.0 Can't Detect SV-1

          I downloaded SuperLab 6.0 and tried testing the Voice-On/Voice-Off responses to measure voice duration.

          Problem: SuperLab 6.0 cannot find the SV-1 Voice Key
          The error message reads, "SuperLab did not find the SV-1 Voice Key" nor any other XID device."

          Attempted Solution:
          1. Reinstalled the SV-1 Voice Key driver
          2. Restarted computer
          3. Restarted SuperLab 6.0

          SuperLab 6.0 could still not detect the SV-1 VoiceKey

          Problem Testing:
          1. I opened SuperLab 5.0 and confirmed that the SV-1 VoiceKey is, in fact, detected in the earlier version of the software
