If you feed a computer enough ice cream flavours or pictures annotated with whether they contain giraffes, the hope is that the computer may eventually learn how to do these things for itself: to generate new potential ice cream flavours or identify the giraffehood status of new photographs. But it’s not necessarily that easy, and the mistakes that machines make when doing relatively silly tasks like ice cream naming or giraffe identification can illuminate how artificial intelligence works when doing more serious tasks as well. In this episode, your hosts Gretchen McCulloch and Lauren Gawne interview Dr Janelle Shane, author of You Look Like A Thing And I Love You and person who makes AI do delightfully weird experiments on her blog and twitter feed. We talk about how AI “sees” language, what the process of creating AI humour is like (hint: it needs a lot of human help to curate the best examples), and ethical issues around trusting algorithms. Finally, Janelle helped us turn one of the big neural nets on our own 70+ transcripts of Lingthusiasm episodes, to find out what Lingthusiasm would sound like if Lauren and Gretchen were replaced by robots! This part got so long and funny that we made it into a whole episode on its own, which is technically the February bonus episode, but we didn’t want to make you wait to hear it, so we’ve made it available right now! This bonus episode includes a more detailed walkthrough with Janelle of how she generated the Robo-Lingthusiasm transcripts, and live-action reading of some of our favourite Robo-Lauren and Robo-Gretchen moments.

Chat about the latest Lingthusiasm episode, share other interesting linguistics links, and geek out with other linguistics fans. (We even made a channel where you can practice typing in the International Phonetic Alphabet, if that appeals to you!)
