On September 19, it was reported that ChatGPT's advanced voice mode may be launched on September 24. Recently leaked code shows that this feature is expected to be released first on the mobile app rather than the web version. In addition, some users have found that the relevant FAQ has been updated and the description page of the standard voice mode has also changed. It was previously mentioned that the feature will be launched to all users before the end of autumn, but now it has been changed to a more vague "coming soon" message. At the same time, the voice mode UI of the macOS version of ChatGPT has also been updated. The original black circular icon has been replaced by a sky animation, and a quick voice selection button has been added. There are only four voices at present, but the interface design shows that more voices may be supported in the future.
