It's not often that we have repeat guests on Lunch with Leon, but we've made an exception for the wonderful Emma Hignett - aka the voice of London Buses, The Elizabeth Line, Go North East and Go Yorkshire. Leon chats to Emma, a brilliant voiceover artist, about her unexpected career in transport, the impact of AI on the voiceover industry, some of the quirkier stops she's recorded in her 'bus voice' and more. Listen to the end for a bonus musical surprise!
