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.

    This is certainly a long-awaited plugin and I am so much grateful to this plugin's developers. I have so far tested it in three separate Moodle 3.7 installations (dedicated-server based, shared-server based, and localhost) and it works wonderfully.

    Thanks for the feedback, Hakan. smile

    We've kept v1.0 as simple as possible, but we'll be refining it over the next several months. I should signpost that in the next version, we'll probably be turning on the video recording option, and as a result, it'll require a slight rename.

    Thank you for this beautiful plugin. This plugin will prove its worth especially for foreign language education. However there is one problem: the recording option does not work on an iPad. Is there a solution for that? Are there browsers for the iPad that work? Will there be a version in future that is suitable for the iPad?

    Hi Johannes,

    We're only just planning roll-out to OU students for the next academic year ourselves, so it's still very much early days. All we've really done for v1.0 is make RecordRTC a dedicated quiz question type (rather than being Essay with the Atto RecordRTC button available - there were obvious benefits to streamline the interface). Therefore it has all the support (and current issues) of the 'main' RecordRTC plug-in, the latest being reported at

    In the short-term, I assume that Chrome on an iDevice should work, but if I recall correctly, Apple have a security policy of not allowing websites access to the microphone. I need to test that assumption myself, but my understanding is that app access to the microphone is OK, which is why we'll be working on ensuring the question works with the Moodle App for September.

    OK, I've now had a chance to directly test wider support. It looks like the browser is completely cut off from the device microphone on iOS devices (whether it is Safari or Chrome doesn't seem to matter. Additionally, Chrome for iOS doesn't include the necessary audio support of its Android/Windows siblings). That seems to be a deliberate platform limitation rather than an issue with the plug-in.

    Checking the Moodle App on iOS, RecordRTC (when a button in Atto), doesn't seem to work either. However, I am pretty sure that non-browser apps *can* access the microphone with user permission when its built in. I am not an expert in this area, but it appears that Moodle will need to add support for RecordRTC into the app, and also add app permissions for microphone access. I'll discuss this with the manager who looks after the OU-branded version of the Moodle App as they are better placed to raise this general app/iOS issue.

    Dear Chris,
    Thank you very much for your efforts to make this plugin usable for iOS devices.

    Thanks for what you are doing.
    Unfortunately I can't use it. I loaded the plugin on a 3.8 platform but when I test to see how a student receives the question, I get this error: "WebRTC not supported
    Your browser offers limited or no support for WebRTC technologies yet, and cannot be used with this type of question. Please switch or upgrade your browser. "
    Maybe this happens because my site is not https? Since I have not uploaded the SSL certificate or are there other problems that I can't understand?
    Thanks for your help.

    That is correct. It is a limitation that Web browsers put on audio/video recording. It can only work on HTTPS sites. There is nothing we can do about this in the plugin. (In this day and age, really, ever site should be HTTPS.) You will find that the same thing applies to the record audio button in the Moodle editor tool.

    Thanks Tim. As I imagined

    Hi from France ! Thank you for your wonderful plugin !
    I just want to inform you that I had the same error message than Antonello Ratta with Safari on Catalina (10.15.4) while my site works on HTTPS. The problem disappears when I use Chrome ou Firefox and the plugin works fine. So, I will suggest my students to use this two web browsers. Thanks again !

    Correct. Safari does not support the Web RTC technology that this question type uses. (

    How do I add the button, other than by the editor?

    Hi Jose,
    This is a Moodle Quiz question type rather than the general Atto-based record button. There's more info on the Atto button at:
