Word of Mouth

Michael Rosen and Dr. Laura Wright are joined in the studio by a virtual assistant and Tom Hewitson - conversation designer for the likes of Siri, Alexa and Cortana. They discuss whether virtual assistants can ever speak like actual humans, and how us humans are developing a new vernacular for machines. Mitsuku is a bot that won an award for most human-like AI and Tay is a now-deceased bot who learnt to speak like a Nazi. Producers Eliza Lomas & Sally Heaven.

Michael Rosen talks to Dr Tiffany Watt Smith about the words we use to try and describe our emotions, and what that can tell us about the way we feel now and have felt at different times in the past. Sadness once occupied the place that happiness now does in terms of life aspirations, and nostalgia was listed as a cause of death on death certificates - in the twentieth century. Producer Beth O'Dea.

How do fonts change the meaning of a message? What was Comic Sans invented for? Why was Obama's first election campaign so typographically bold? And which font would make you buy one chocolate bar over another? Michael Rosen is joined by graphic designer, author and the font of all knowledge when it comes to fonts, Sarah Hyndman, to discuss the psychology of typefaces. Sarah is the author of 3 books, including 'Why Fonts Matter' and 'How to Draw Type and Influence people'. She is also the founder of the Type Tasting studio, which aims to change the way we think and talk about typography through interactive and sensory experiences.Producer Rebecca Ripley.

Word of Mouth returns with a special programme in which Michael Rosen and guests Marina Warner and Barry Smith discuss the state of language and public debate. With the rise of the internet there is more political discussion than ever. Yet this torrent of words seems to carry less understanding than ever. This has been attributed to many causes. Some say it is the anonymous nature of internet discussions, or the increasing disparity between rich and poor, or even the efficacy with which media (and propaganda) organisations can affect public opinion. But possibly the problem lies in language itself. Traditionally, political language has been a shared endeavour through which we express our differences. Perhaps now even the language itself has become partisan - words carry profoundly different meanings for different people and the shared understand that public debate relies on is much reduced. Two people can share a word - say government or sovereignty - but if the frame of reference for what that word means has become radically different it's hard to find the common ground on which meaningful debate can happen. So Michael Rosen and his guests are looking at the state of current political and public debate, delving into the philosophy of language and seeing how words get their meaning in the minds of their users. Perhaps, on top of all our other attendant crises, we can claim to be living through a crisis of language. Producers James Cook and Beth O'Dea.

Why do we 'let the cat out of the bag' or 'go the whole nine yards'? What is a hackle and why might it be raised? What does it mean to 'fribble'? Or to have a 'schnapsidee'? And what are 'cupid's kettle drums'? Michael Rosen and Dr Laura Wright are joined by Paul Anthony Jones, the writer behind the popular etymology blog Haggard Hawks to talk about the origins of common idioms, the stories behind words we use every day, and the forgotten words Paul would like to see brought back into use. Paul is the author of six books of word lore and linguistic trivia, including Haggard Hawks and Paltry Poltroons: The Origins of English in Ten Words, The Accidental Dictionary: The Remarkable Twists and Turns of English Words and - most recently - The Cabinet of Linguistic Curiosities: A Yearbook of Forgotten Words. Producer: Mair Bosworth.

Michael Rosen and Dr Laura Wright are joined by CN Lester, author of 'Trans Like Me: A Journey for All of Us' to talk about language and gender identity. What does it mean to be transgender and how is language being used (by and about) people who identify as transgender, non-binary or genderqueer? Producer: Mair Bosworth.

Michael Rosen and Laura Wright explore how diseases are named and the political, economic and social impact of disease names past and present. Joining them are Laura Spinney, Science journalist and author of Pale Rider: The Spanish Flu of 1918 and How it Changed the World and Professor Peter Piot; Ebola co-discoverer and AIDS pioneer, currently Director of the London School of Hygiene and Tropical Medicine and professor of global health.Producer: Sarah Addezio.

We used to sign off letters using "yours faithfully" or "yours sincerely", then email came along and it was all "kind regards" and "best wishes". Now, it seems, we hardly sign off at all. With so many forms of written communication- email, text, Twitter, What's App- what new etiquettes are emerging, and where are 'digital natives' simply getting it wrong? Emma Gannon is author of Ctrl, Alt, Delete: How I Grew Up Online, and hosts the podcast of the same name. Producer Sally Heaven.

Vocal coaches Gillyanne Kayes and Jeremy Fisher, authors of This is a Voice, give Michael Rosen a workout. They get him to read against natural pitch and intonation, which proves nearly impossible, and make him match his speaking pace to a walk around the studio. What we do with our consonants and our ability with a tongue twister also turn out to play a part in the ways in which we speak. Producer Beth O'Dea.

Michael Rosen and Dr Laura Wright are back with a new series of Word of Mouth, and appropriately enough they're starting with Hellos. And greetings. Former diplomat Andy Scott has greeted people in more than 60 countries, and he's written a book about his experiences called One Kiss or Two? The origins and psychology of greetings provide a rich subject and by the end of the programme they may all even reach an agreement about how many times to kiss.. Producer Beth O'Dea.
