How to fix exception: Sanako Graph Data not installed

  1. Problem: When trying to administer an oral exam, using model imitation, source: file, I could not, but rather I got this error 20130703_141106
  2. Root: The same feature had worked in the morning – however, then the Sanakorecorder interfered with the Sanako tutor. Turned out that the Sanako tutor had been installed over a Sanako Student recorder which caused the tutor pc to connect to itself (distracting, also potentially a liability since it eats up licenses if not managed). In between morning and afternoon exam, the student recorder was uninstalled, but without the required functionality testing afterwards. So this exam had to become the test.
  3. Workaround: Reinstall the student recorder. We used the “test the  Sanako installer” program on my home page to not delay the exam too much. 20130703_142634
  4. Solution: do not install the Sanako tutor over a student installation in the first place.
    1. Either remove the Student recorder after imaging the teacher station with the student image,
    2. or better, image the PC without the added baseline task “Student recorder”.

QuickNotes: For ELTI 201/202/501 Student Recordings with Sanako Study1200

  1. This is 20 students class doing a model imitation for English phonetics and grammar – use right half of classroom plus 2 rightmost columns of left half.
  2. Have a couple of spare student computers logged in as labadmn (not  as presenter: has no permissions to s-drive to  save recordings) for emergencies.
  3. Your students will log in, then take their break. Wait until entire class shows up in the Sanako Classroom layout. Then you can lock their keyboard and mouse  – but remember when computers go into locked mode, Sanako cannot control them
  4. See, upper right corner “Quick links” for the path to copy/paste. Or, on the  teacher computer in LRC 434, in folder C:\Temp, you can find a shortcut to the Sanako folders
    1. “media” with teacher audio (to be prepared with pauses and beeps once it has been recorded and sent; you can easily prepare it yourself: download and view how with Windows Media Player);
    2. “student” with student recordings
  5. You can download and view with Windows Media Player the (unedited) screencast of our summative walkthrough here.

How to conduct an easy oral exam with Sanako Study-1200 (Model imitation/Question Response) – Part I: The exam administrator’s perspective

This 7-minute screencast explains how to operate the Study-1200 software interface to administer an oral exam, using as audio source the teacher, providing cues live:

  1. 0:00: from selecting the activity and program source,
  2. 1:50: over start and use of the autoscan screen control feature to monitor both audio and screen of the examined students
  3. 3:45: to ending the exam and automatic collection of the exam files.

For an implementation during an actual class-wide oral exam, see Part II of the Study-1200 oral exam.

A 6-minute screen-cast explaining the sanako-lab300-oral-exam-question-response-recording-cycle.wmv

Please consult the transcript for a table of contents:



Here we are administering an oral exam. we are going to play pre-recorded teacher-questions to multiple students, we are going to record their responses and, at the end, we are going to collect their recordings in a batch:


for this, we have all seats where a student is present added to group a, and have set the program source for group a to media file


we monitor the situation on the student computers by accessing menu: other / thumbnail of group, 

the screen sharing is slow here, has been improved somewhat by installing more memory, the crowded screen situation has also been improved by installing a secondary monitor, use it for viewing the thumbnail window


in the group a pane, we use the button: duo launch, and ok the dialogue, to open th estudent recorder on the student computers


in the section:media source, button: file open, we access our pre-recorded question file


in the meantime, the duo has launched on the student computers – as you can see in the classroom layout from the squares on the student seats, as well as on the mosaic thumbnail screens


we double-click on a single thumbnail to demo to the students on the screen projector how to adjust the volume


we click button:transfer to play the volume test file to the students

we have the students record their name at the end of the sound test, to check all recorders, and to be able to identify the speaker in the actual exam file (which will be saved with only the student number in lab 300)

we stop the button:transfer and go to menu:test:response recording

in the pane:”response recording”, in section:”collect”, we click button:”start”

we save the recording in a subdirectory with a meaningful name of our choice

we ok the dialogue that informs us of the response recording

in the window:mosaic, the encoding activity window briefly flashes on the student screens

we browse to the student collect folder, where all subdirectories are saved

we check the folder visibly for the right number (use select all), size or duration of audio files –

it would be even safer, even though more time consuming, to open all the test recordings with audacity, especially on a slow computer, and check the volume graph – open audacity and drag and drop all files onto it


the soundtest is a complete recording cycle. Simply repeat for the actual exam, but

first  close the pane:response recording, to go back to your pane:group,

in section:program transfer, click button:group control, click icon:file/new, to flush the prior test out of the student recorders,

in the dialogue:”save changes”, click no

and this time load the actual exam audio file

once the sound check is done, we could use button:lock for the students to prevent them from interfering with the computers during the exam

Language Lab Techniques for (Self-)Evaluation and Grading of Student Recordings with Audacity

This quick and dirty (not narrated and uncut: time is money, and storage cheap…) video demonstrates a technique in (the free audio editor) Audacity with which instructors and students can more easily (self-)evaluate parallel recordings from (be it model imitation, question-response, or consecutive interpreting exercises in) the language lab (in this case the output of a Sanako Study1200, which automatically gets stored in a folder on network share):




how to load 10 student files à 5mb = 2:30min (but as a batch, allowing you do something else in the foreground instead of waiting)


how to select a part of the timeline to play


how to move tracks up to more easily work with them and the menu


how to play all tracks simultaneously (choir, normally not very useful for evaluation)


how to play only one track (solo): evaluate & compare
