According to ChainCatcher, OpenAI CEO Sam Altman recently revealed on social media that the Alpha version of GPT-4o's voice mode will be open to ChatGPT Plus subscribers this week to help users have smooth conversations without delays.

According to current public information, the ChatGPT voice mode has an average delay of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4), so the user experience is not intuitive, while GPT-4o will significantly shorten the delay time and achieve seamless conversations.
