Text-to-speech conversion\n5. Audio summary sent back\n\n**Perfect for:**\n- Commuting (hands-free)\n- Multitasking\n- Visual impairments\n- Quick content review\n\n**Voice:** Natural AI voice (Alloy)\n**Language:** Auto-detects from content\n\n\nWhatsApp Requirements:\n\nYou will need a WhatsApp business account with OAuth:\n\nhttps://docs.n8n.io/integrations/builtin/credentials/whatsapp\n\nCreate a WhatsApp App and register a phone number (although a test number can be used if its just for one person and you don't plan to make this for public use)\n\nAnd create a System User to then generate a system user token (so that you don't have to manually generate a token every 4 hours.)\n\nhttps://business.facebook.com/latest/settings/system_users\n\nWhatsApp works well once its up and running. However it can be initially a chore as WhatsApp security wants you to verify the business when you make an app, when you register a phone, when you create a system user. So yes, at least 3 different times... possibly up to 5 times.\n\nAnother WhatsApp caveat: \nYou can't send an auto-generated message to a whatsapp users phone after 24 hours, unless that user has replied, special message template or the user has sent the app, a message first.\n\nFor example in the morning, you can send the app a quick \"Hi\" message and from then on, the app can work well.
