OpenAI has revamped the voice mode of its ChatGPT web application, incorporating new features for adjusting speech rates and customizing command prefixes. Users can now seamlessly adjust the voice speed between 0.5x and 2.0x using an intuitive slider, albeit this feature is currently in a beta testing phase. Furthermore, the custom command prefix capability empowers users to save specific commands, ensuring a consistent response style tailored to their preferences. Simultaneously, OpenAI has introduced an upgraded model selector, providing three variations of the GPT-5 model and re-enabling access to GPT-4 for paid users, catering to the diverse needs of its user base.
