[00:00] I just Creed an AI assistant in n8n with a natural sounding voice hey Luna how are you doing please tell me a joke but laugh at your own joke while telling it I'm doing great thanks for asking here's a joke for you why don't skeletons fight each other because they don't have the guts can you picture them just standing there too scared it's so silly what do you think thanks Luna that was quite funny and uh you've got a beautiful laugh by the way tell me a scary story but also sound very scared while telling

[00:31] it also include by dog's name in the story thank you so much I'm glad you enjoyed the joke now let's dive into a spooky tail voice trembling with anticipation it was a dark and foggy night and you were at home with Ruby snuggled on the couch when suddenly you heard a strange noise outside I'm already shivering just thinking about it it sounded like a low growl and Ruby's ears perked up her Instinct kicking in this is way more natur than the text to speech models that we're used to and

[01:02] this is because this is using the new Audio model from open AI called gp4 mini text to speech and you would also have noticed the agent somehow knew what my dog's name was and that is because this assistant collects important memories about the user in order to provide personalized responses if you would like to learn how to use the new Audio model from open AI in n8n then check out the full video on my channel
