How to manage balance on stereo audio using Audacity, Sanako student recorder, or any audio player on Windows

  1. For language lab use, stereo is more important than usual, since the channels may carry source versus translation/interpretation, L1 versus L2, teacher versus student, model versus imitation and so forth.
  2. You can choose which channel to listen to by adjusting the balance for stereo playback.
  3. In the Sanako Student recorder (free for all), click here: image
  4. In Audacity, click here:: image
  5. From any other player on Windows, hold Win-key and press R, type mmsys.cpl, on tab playback, double click the speaker you are outputting to, and  on tab levels, change “Balance”: image

First steps with the teacher-training-setup for Sanako Study 1200 v7 in a deepfrozen computer lab environment

  1. I remember a time when the vendor travelled onsite to provide faculty induction into the Sanako Lab300, they set up the student PCs with a special version of the tutor software that multiple faculty could gain hands-on experience during a workshop.
  2. I have sorely missed this facility during my own 8 years’ of experience training faculty in using the successor product, Sanako Study 1200. No longer: With Sanako 7, Sanako provides to the digital audio lab manager an installer that sets up a similar environment for faculty in a Sanako Study 1200 lab. Below are some observations how to get this to run what should be a fairly typical HE language lab environment
  3. Install, in frozen state, as admin:
    1. Uninstall Sanako student recorder from appwiz.cpl
    2. Install "S:\COAS\LCS\MYDEPT\LRC\Secure\software\Sanako\7\TeacherTrainingSETUP.EXE" (right-click, run as admin)
    3. Is mostly hands-free, but I’d prefer an MSI with a /quiet install option, then I could automate that.  
      1. One could write AutoIt script compiled to .exe that uninstalls student recorder? Need to know the msicache location ?
    4. Neither Uninstall of student recorder nor install of teacher-training-setup require a restart  -  is suitable for installation on otherwise frozen lab installation
  4. Additional setup required:
    1. I got an error about corrupt student settings file, but it worked.
    2. Loading students from "corridor"
      1. On unfrozen office computer, I got an error about student settings corrupt, but teacher could load students
      2. On frozen lab computer, I get no error, but teacher does not see students, although 5 have been started – Is an original student settings hanging around?
      3. After tutor setup (do not require tutor login) and restart, I get this error on the tutor: image
      4. And this crash of the student: image
      5. But now is see these signs of success :
        1. on student timage
        2. on tutor this : image
        3. And it works: image
    3. We have to unblock tutor in firewall twice:
      1. Initiate a screen sharing , then unblock : image
      2. For audio: initiate a model imitation with collect, then unblock.
    4. Set Collection path:
      1. Initiate a homework collection , set collect path to a suitable folder (here S:\COAS\LCS\LRC\sanako\student).
      2. Not needed for audio collection.
    5. Other observations:
      1. Uses file download, not stream audio, to students: You can see the tutor and the student applications at the same time, monitoring the effects your tutor operations would have in the classroom
        1. Why at first 2 students and then 3? image
      2. Remote control:
        1. Note that screen sharing will switch aero off on your computer
        2. Note that button:"collaborate" does weird things to your mouse, make sure you can even get back to the button:"monitor" to turn it off.
    6. Setup TeacherTrainingSETUP for each workshop participant.
      1. The msi packages contained in teacher training setup as of Fall 2013, in case you ever get around automating the installer using AutoIt that you can deploy it from teacher station instead of having to touch each machine, please share: imageimageimage

    "Server busy" error from Windows 7 speech recognition?

    1. Problem: We see this error frequently, on various LRC PCs, when logging in. clip_image001
    2. Root cause: It looks like this is a speech recognition related error on the LRC PCs. Now that I am testing speech recognition on my office PC, I am seeing this error there also when starting speech recognition (together with a slowdown – not sure what is cause and effect there).
    3. clip_image002
    4. Workaround: Not auto starting Windows 7 speech recognition, but having users launch it form the desktop when needed, should alleviate this problem.
    5. Resolution: Still investigating.

    Input languages missing on PC21 to PC31

    1. I only had a chance to check the PC’s in the title.
    2. This is the size of a good language bar: CAM05715
    3. These PCs are missing input languages when I am logged in:
    4. CAM05714CAM05709CAM05716CAM05717CAM05720
    5. my phone has a poor camera, so this needs double checking:
      1. looks like pc29: CAM05719
      2. unclear which, but appears to be in 2nd row: CAM05708

    Prevent multiple user login to avoid “Another instance of Tutor is already running in another user’s session on this computer” by disabling fast user switching

    1. Problem: As reported earlier (in the Spring and in the Fall term),  for the student PCs, Sanako issues (but likely also general performance problems, and reportedly problems on classroom computers outside of the LRC) caused by multiple users being logged into the same PC – not limited to logging in from remote via MSTSC -  seem on the increase this term (this year?), also on the teacher PC, where they prevent the digital audio lab from starting:image
    2. Workaround: force restart of the computer (time-consuming, though).
    3. Solution: Avoid, better prevent multiple user login, maybe by disabling fast user switching?
      1. Registry: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System\HideFastUserSwitching =1, or
      2. Group policy: Computer Configuration\Policies\Administrative Templates\System\Logon\Hide Entry points=Enabled.
    4. Other considerations:
      1. Side effects: unclear?
      2. Root cause: Not enough data. Why do users remain logged in in the first place?

    Common commands in Speech Recognition for all languages supported

    (I cut a corner and left out the language variants ZH-TW and EN-UK, sorry, we do not teach those here):

    Faculty Workshop Spring 2014: "Mira, mamá! Sin manos!". Practice speaking L2 with automatic intelligent feedback by operating LRC PCs through speech recognition instead of keyboard/mouse

    1. When: March 28, 2:15-3:15, April 4, 2:00-3:00
    2. Where: LRCRoomCoed434
    3. What: Language learning speaking practice assignments with automatic intelligent feedback using Windows Speech Recognition
      1. As part of the foreign language tools we installed with Windows 7 this past Fall, we got speech recognition on the LRC PCs for 6 languages (English, Chinese, French, German, Japanese, Spanish ) representing over 85% of our enrolment.
      2. Unlike the speech recognition that comes with learning content packages like Auralog or Rosetta Stone
        1. which had to be purchased, for individual languages, but stopped functioning on the server on a long time ago,
        2. was limited to built-in content ,
        3. was restricted by a separate account system,
      3. Windows Speech Recognition is
        1. free (with the operating system), runs on the local lab pcs, and should be a bit more robust,
        2. content agnostic and hence can integrate flexibly with your curriculum and contribute meaningfully to your students’ progression,
        3. can be integrated with the existing user accounts.
      4. We combine Windows speech recognition with the new LRC screencast software, MS-Office and Moodle to offer a simple self-access assignment type that
        1. is available on all 45 LRC PCs (= scales even to large enrolment languages and 1st-year classes that cannot use the 24-seat Sanako for face-to-face speaking proficiency training)
        2. and blends the “artificial intelligence” of speech recognition with human intelligence to provide students with immediate automated feedback during pedagogically sound speaking practice, with minimal grading overhead for the teacher (= grade secure assignments by looking at the very end of a student-submitted screencast).
      5. This workshop will show actual speech recognition usage and assignment samples
        1. so far in English, French, German;
        2. if you want to bring your own samples to this workshop – there might still be time- , or to an upcoming faculty showcase, I can help you during my biweekly LRC clinics (see LRC main schedule, or schedule your own).
      6. We will step you through – hands-on, including tips&tricks – a sample voice training and assignment completion: Better than my made-up assignments would be if you could bring one or more concrete tasks to be solved using speech recognition that we could prepare assigning to your students. Here are some parameters for that:
        1. Speech recognition can replace mouse and keyboard when operating the computer. Voice commands are simpler than sentences, so this could be a beginner task, as long as you have students study the (limited) command vocabulary (which I will make available during the workshop).
        2. Speech recognition can replace any writing task with dictation. Suggestions for proficiency levels:
          1. I have dictated a web page assigned for reading comprehension in a textbook used in 1200 or even a as a false beginner.
          2. However, a one-time training helping the computer recognize an individual’s voice is required and comes sentences that vary in complexity between languages
            1. English: very easy, Beginner level;
            2. German, French: let’s have a look together, I’d say 1202 level;
            3. Japanese: 3000 level, I was told;
            4. Please test with me during the workshop: Spanish, Chinese.
