The accessibility benefits of using audio in teaching and learning

My last 2 posts in this blog, have looked at the use of audio within teaching and learning as follows:

In this post I want to think about some of the accessibility benefits and issues for this area of work. Firstly (and sadly) a lot of people use accessibility as an excuse not to use audio more, often stating that they don’t want to use audio in case they have a deaf learner in their class.
No hay más ciego que el que no quiere ver...

This is a commonly misunderstood area – as (although it may sound silly) many deaf learners actually find audio content really useful. Agreed, if someone has no hearing then audio is of no use to them, but many people that are identified as being deaf have some hearing, and many of them will have hearing aids that will amplify noise so that they can hear something. For these learners accessing a lecture is often difficult as the hearing aids will pick up all noise in the room, including the lecturers voice, mutterings from other learners, the hum of the strip lighting, the squeaking of pens etc. making it very hard to hear. The use of induction loops has helped this issues to a certain extent, but still isn’t ideal, as you hear the tutors contribution but not necessarily what other learners say. If however as part of the process an audio file has been produced summarising the key learning points (and remember you can always get the learners to do this – see my post on ipadio) – a deaf learner can in a quiet environment (e.g. their bedroom) listen to this – altering the volume accordingly so that they can hear it through an ordinary audio player and pick up some extremely valuable information that would otherwise have been missed. With this in mind, when I record audio, I amplify the recording slightly (which is very easy to do with things like audacity) – as it is always possible to turn the volume down, but it isn’t possible to turn the volume up above its maximum.

Another question that I am often asked is “Do we need to provide a transcript for all the audio recordings we make?”. This question again is another barrier (excuse) that stops people using audio, as the time to create such a transcript puts them off.

Personally, my interpretation of the law (and I am not a lawyer – so do not take this as legal advice) is as follows:

The law (Equality Act 2010) states that

  1. We have to make reasonable adjustment.
  2. We have an anticipatory duty, to be prepared for a variety of disabilities and associated possible adaptations.

So – what does that mean? Part 1 is simple – yes if we are using audio and we have a learner who states that they need a transcription then we need to provide it.

Part 2 – is more tricky. Many people interpret this as we should produce the transcripts upfront, but this doesn’t make sense to me, as if we followed that logic through it would mean for every session someone delivers, they would have to turn up with their resources printed on a variety of colours of paper, in different fonts sizes and fonts, and in audio format, Braille format, videoed as British Sign Language etc. This to me wouldn’t be a reasonable expectation.

So I don’t automatically provide transcripts, however what I have done with a few organisations that I have worked with is ensure that there is a mechanism in place to create such transcripts if required (e.g. if a student asks for one) – very quickly (this I think is a reasonable adjustment). Many people ask me if there is a technological solution to converting audio to text, and sadly there isn’t a fully reliable one, so my solution would be to just employ a very fast typing temp, who could listen to the audio files, and transcribe them. The problem here is many organisation would then argue over whose budget would pay for this temp (e.g. is it central, is it the teaching team(s), is it learner support). Personally I think it should be a central budget – as the key here would be getting it done quickly and the organisation should have a procedure in place to do this if a student requests it. I am aware that most organisations don’t, which is a shame as it would be a very simple mechanism to put in place.

So in summary – we should not avoid using audio on accessibility grounds, instead we should embrace it, if we can make sure that audio recordings are clear and recorded at above average volume then great. If we do produce transcripts up front then brilliant but of not possible then having a mechanism in place to create them should suffice.
