How voice AI suddenly got so good

Talking to computers can be frustrating—ask anyone who’s been on the phone recently to automated customer services. A decade ago, the arrival of voice assistants such as Amazon’s Alexa or Apple’s Siri was supposed to mark a new era in how humans interacted with machines, but their limitations quickly became apparent. In recent months, though, computerised voices seem to have moved light-years ahead. You can now have a conversation with OpenAI’s ChatGPT. You can clone your own voice. You can even generate and interact with a personalised podcast, where AI presenters will discuss any documents you like. The voice AI revolution has finally arrived. How will it change the way we interact with the digital world?
