Make life simpler in the language lab by disabling extra audio panels

  1. Problem: Having multiple audio panels enabled can led to too many options = sources of errors and confusion.
    1. Software (e.g. Saba Centra) may defaults to different audio panels (front “Microphone” preferred over a “Rear Input” that can be used as a Microphone and is the preferred device in your lab (for security, safety and ergonomic reasons).
    2. Students may make erroneous assumptions and try to reconfigure the PC audio by plugging cables into a different outlet.
    3. ESP Panel  software detects plugging in of devices and asks users to identify whether microphone or line-in device has been plugged into rear input which confuses our users even more.
  2. Software configuration:  On Dell Optiplex 760 under Windows 7 , you can
    1. run  mmsys.cpl,
    2. go to tab:“recording” devices
    3. to disable the front panel input microphone:
      1. select “microphone”(that is the front input)
      2. right-click and  choose “disable”: image
      3. result: image
      4. right-=click and uncheck “show disabled devices”
    4. to configure the “rear input”:
      1. select and click “properties” image
      2. go to tab “custom” (may require having an add-on driver installed, consult the DELL driver update utility) image
      3. check “use as microphone”
      4. check (optional, recommended): “microphone boost”
    5. “Ok” out of all mmsys.cpl dialogues and (for good measure) restart computer.
  3. Test your software configuration to work (listening, recording) with the applications used in your lab:
    1. Sanako student recorder
    2. Saba Centra
    3. Audacity
    4. Voicethread
    5. Moodle: Audio and Kaltura (even though no webcam)
    6. Etc.?
  4. Hardware configuration
    1. Plug your headset microphone and speaker into the rear audio panel. Tie the microphone cable down with a cable tie. Students have managed to pull the cable through the cable tie, so tie the cable into a knot around the cable tie to prevent that
    2. Tape (plastic that student cannot push a plug through easily) over the front audio panel and put a label on top: “Do not use! Get help at desk!”. Instruct your help desk student staff.

How to provide students with blended human/computer-automated feedback on their speaking using a dictation with speech recognition assignment screencast

  1. Teachers often feel there is never enough time for grading students’  speaking proficiency. Fortunately, we can now automate feedback on pronunciation using Windows 7 dictation with speech recognition.
  2. This feature will be  available for 7 languages on Windows 7 in the LRC, here is a demo for a reading exercise dictating German.
  3. An assignment step-by-step could look like this: Students
    1. record a screencast of their dictation,
    2. read a text to the computer in MS-Word,
    3. turn track changes on in MS-Word and correct the text (immediately or after dictation) where the computer could not recognize their speech,
    4. upload their screencast to Kaltura in Moodle.
    5. To grade the performance, the teacher has to review only at the very end of the screencast to see how many corrections the student needed to make (when it doubtabout the speech recognition validiiy, the teacher can easily jump to the screencast segment in question and, if necessary, override the speech recognition).
  4. This could be a regular assignment type since it provides the following benefits:
    1. immediate automated intelligent feedback for the student
    2. little grading overhead for the teacher, so that the teacher can concentrate her work on providing aural feedback on student recorded speech as a highlight maybe twice per term, maybe after mock exams  before a midterm and final exam
    3. some multimedia pieces demonstrating language proficiency for the student’s ePortfolio.
  5. Requirements:
    1. a quality headset (we use Sanako SLH-07Sanako SLH-07 USB)
    2. Windows 7  Enterprise/Ultimate with Language Packs,
    3. knowing how to switch the display language, (optional/recommended:) TBA:a simplified language switching facility,
    4. individual voice training data: speech recognition users have to train the computer  – once, even in a deepfrozen computer enviroinment,  since we enabled you to save this data to and restore it from a flash drive or personal network share space,
    5. a reading text (often authentic texts can be taken straight from the textbook, to fit in with the syllabus, like in this example from Treffpunkt-Deutsch 1st-year German),
    6. MS-Word with track changes
    7. screencast software (we use MS community clips)
    8. a way to submit the results to the teacher (we use Moodle with Kaltura video uploading (example for teachers, students do it similarly), but email could be sufficient depending on screencast length and attachment size allowance).

Overview of MS natural language support on Windows Vista+7/Office 2007, 2010

The LRC writing input methods (“keyboards”) are not configured right

  1. clip_image001
  2. In intl.cpl, we do not want keyboards installed for western and central-European (= characters a-z, merely altered by diacritics) languages, including US. We type these languages, including US-English, with the us-international keyboard extended 2.1, which has to be set as default, and that US-English extended 2.1gets checked as the keyboard for all western languages ("show more"). The regular US keyboard gets removed/made invisible to the user, and with any reasonably recent version of MS Sysprep tools, that is no problem anymore.
  3. For non-Western languages, the built-in windows keyboards should be "checked", and also the alternate input that we had to download and install methods need to be "checked" under their languages: MS Maren, Google input methods nee to be enabled (checked): e.g. Farsi is not enabled (checked).

How you can reuse your speech profile even on deepfrozen Language resource center computers

  1. “A [Windows Speech] profile is basically the collection of all settings and information about how to recognize your voice when using Windows Speech Recognition. Before changing the language used or letting other persons use Windows Speech Recognition it is best to create a new profile so that your current one will remain unaltered”.
  2. To be able reuse your effort training the computer to recognize your voice speaking in your study language – even though the LRC Windows 7 computers get reset when restarted -, you can backup, and later reload, your Speech Profile, preferably to your H:-drive.
    1. The Microsoft tool that allows you to do that has been put on WSRProfile.exe  desktop of the LRC Windows 7 PCs. I can copy these instructions directly from the Microsoft blog page:
  3. Double-click WSRProfile.exe to start the WSR Profile tool wizard. image
  4. To back up a speech profile using the WSR Profile tool, select Backup my speech profile.
    1. In the Select your Speech Profile dialog box, choose the speech profile you wish to back up and then click Next. image
    2. The wizard will prompt you for a filename and location to save the file. When you have entered this information, click Next. The WSR Profile tool wizard will start the backup process of the selected speech profile. image
    3. After the backup operation successfully finishes, click Close . image
  5. To restore a speech profile using the WSR Profile tool, select Restore my Speech Profile.
    1. On the File to Restore wizard page, click Browse and locate the backed up speech profile, and then click Next.
    2. Choose the speech profile you want to restore to.
      1. Select Use the current speech profile if you want to overwrite the current default speech profile.
      2. Select Create a new speech profile if you want to restore to a new speech profile. If you choose to restore to a new speech profile you will be prompted to provide a name for the new profile.
    3. After the restore operation successfully finishes, click Close.
