The technology has developed rapidly in the past year, becoming far more realistic and nuanced
OpenAI was forced to apologise to actor Scarlett Johansson last week for using her voice –- or something very similar –- on its latest chatbot, throwing the spotlight on to voice-cloning tech.
Although OpenAI denied the voice they used was Johansson's, their case was not helped by CEO Sam Altman flagging the new model with a one-word message on social media -- "Her".
Johansson voiced an AI character in the film "Her", which Altman has previously said is his favourite film about the technology.
