On February 26, OpenAI released an important announcement on the X platform, announcing that ChatGPT's Advanced Voice Mode will be opened to all users for free from now on. This move marks a new stage in artificial intelligence voice interaction technology, providing users with a more intelligent and convenient experience.
It is understood that ChatGPT's advanced voice mode is developed based on the latest GPT-4o mini model. Although this is a lightweight version, its performance is already comparable to the full version of the GPT-4o model by optimizing computing efficiency. This means that users can enjoy a smoother voice interaction experience without sacrificing functionality.

At present, advanced voice mode has fully supported ChatGPT desktop applications for macOS, Windows 10 and Windows 11 systems. Users can choose their favorite sound from 5 different voice options, and also support custom prompts and dialogue content review functions, further improving the flexibility and personalized experience.
OpenAI's free and advanced voice mode not only lowers the threshold for users to use advanced artificial intelligence technology, but also injects new vitality into the development of voice interaction field. This measure will promote the popularization of artificial intelligence technology in daily life, bring users more efficient and intelligent interaction methods, and lay the foundation for more innovative applications in the future.
