How to provide students with blended human/computer-automated feedback on their speaking using a dictation with speech recognition assignment screencast
- 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.
- This feature will be available for 7 languages on Windows 7 in the LRC, here is a demo for a reading exercise dictating German.
- An assignment step-by-step could look like this: Students
- record a screencast of their dictation,
- read a text to the computer in MS-Word,
- turn track changes on in MS-Word and correct the text (immediately or after dictation) where the computer could not recognize their speech,
- upload their screencast to Kaltura in Moodle.
- 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).
- This could be a regular assignment type since it provides the following benefits:
- immediate automated intelligent feedback for the student
- 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
- some multimedia pieces demonstrating language proficiency for the student’s ePortfolio.
- Requirements:
- a quality headset (we use Sanako SLH-07
) - Windows 7 Enterprise/Ultimate with Language Packs,
- knowing how to switch the display language, (optional/recommended:) TBA:a simplified language switching facility,
- 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,
- 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),
- MS-Word with track changes
- screencast software (we use MS community clips)
- 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).
- a quality headset (we use Sanako SLH-07
