There seems to be reasonable consensus that for #languageLearning, putting images on the front of flashcards is a decent idea for increased memorisation and reduced reliance on translation. Obviously this doesn't work at all for #blind people.
Does anyone have any resources on the efficacy of an audio-based alternative? For example, if I'm trying to acquire the Spanish term for "washing machine," is it at all useful to have the front of the card play a short sound from a spin cycle?
I'm interested in any resources exploring and evaluating this as a technique, as well as practical experiences or guides from people who've done this.
