This question type is like the standard essay question type, but instead of writing some text, students have a recording widget where they can record some audio (in future, we plan to also add video recording). We've basically taken RecordRTC ( and implemented it as a question type. 

We consider this an evolution of an Essay question with RecordRTC buttons available to students. We have essentially taken the existing parts and distilled them into a specific question type for the ease and convenience of teachers designing quiz questions and for the students taking them.

Like the standard essay question type, it still requires human grading.

While this question type has obvious uses in Moodle Quiz, it has been primarily designed to be used in an embedded question context (see

This question type has two behaviours: deferred feedback, for use in formal Moodle Quiz tests where a tutor would mark the students' recordings; and a new self-rating behaviour, where students mark themselves.

The self-rating behaviour is used essentially whenever the behaviour is interactive or immediate. We have assumed two use-cases: 1) the student listens to a 'model' audio clip and then records their attempt to follow it. They compare the two clips, and then rate their mimicry. Or 2) the student attempts to pronounce a written sentence verbally, and the feedback contains a model pronunciation clip, allowing the student to then compare the clips and self-rate their accuracy.

This plugin was created by The Open University UK, specifically for its School of Languages and Applied Linguistics.

(We hope that we could look at giving Essay a self-rating behaviour next, which could be used in a similar embedded fashion as an alternative to Pattern Matching sentences. Although if you're thinking about that area already, you might find Gordon Bateson's essay auto-grade plugin of interest.)

Potential privacy issues

You should consider the fact that under GDPR, a recording of a user's voice is personally identifiable data (it is arguably also biometric data). Such 'Special category data' requires extra protection.

    The code is done, and we are running it at the OU. I must find time to upload it.

    I've just tried this plugin and thought I would place an update here. It seems that iDevices can now record and save to an assignment, however, when using an iDevice there is no way to see or hear your recording. I think this must be down to the format things are saved in. Is it possible to have an option to save audio as MP3 and video as MP4?

    Anyone would think that Apple has a strong business incentive to keep people using apps sold through the app store, rather that HTML 5 web pages that just work wink Every other browser supports .ogg (completely open format). Meanwhile, other browser can't record in MP3.

    Yes, we plan do to something about this, when we can work out what, and how.

    That is not the most helpful error message ever. If you can turn on debugging output ( that might give more clues.

    Hi Tim, Chris and Mahmoud,
    My team were investigating this plugin and after testing decided to pursue a different solution due to the need for iOS-compatibility. I've run into an issue when trying to uninstall it. The Question Instances Report claimed to see 2 instances on our system, one visible and one hidden. I went in and deleted the visible instance, and the Report changed to only show the hidden instance, as expected. I then went in and found the hidden instance, and deleted the quiz containing it. After doing this, the Question Instances Report still claims to be able to see one hidden instance, and thus won't give me the option to uninstall. Has anyone else reported behaviour like this, and is there a known fix for it? Any help you can offer is greatly appreciated smile

    @salvador mtz - This question type does not support Moodle 3.5.

    @Keenan Nunes-Vaz after deleting the quiz that uses the question, you then need to find that question in the question bank, (you will need to use the 'Also show old questions' option) and delete it again - which probably requires restoring it first.

    We are going to do a work-around for Apple's non-support of open audio formats when we can, but we keep having too many other things to do.

    Thanks Tim, that solved it! Enabling 'Also show old questions' revealed the hidden question, enabling me to delete it, which itself enabled me to uninstall the plugin. Thanks for your prompt response smile.

    Thank you very much for Plugin. It's amazing.

    Does it support version 3.11 ?

    It probably works in 3.11, but I have not had time to testing it myself. If you are able to try it, please comment where with your findings.

    Hi Tim,

    This question type is not supported on Moodle mobile app.
    Is there any way to make it functional on the mobile app?

  • Mon, Oct 4, 2021, 4:30 PM
    Hi @Amit

    The underlying recording tech used for this question type is the same as the Atto WebRTC tech, so we are waiting for Moodle to support RTC in the Moodle App first.

    Although another blocker is that Apple do not currently support the open-source WEBM video or OGG audio formats.

    We have just got an MP3-based audio version out ourselves that covers desktop/laptop-based Apple Macs, which if we haven't already shared, we will do as soon as we've ironed it out fully.

    However, I understand that Moodle and Apple are currently discussing and iOS may support the open-source standards soon.

    Best wishes,
