OpenAI presented possibility of voice chats with ChatGPT on Android and iOS back in September, allowing users to have real conversations with the chatbot. However, the company then made this feature available Plus and Enterprise subscribers only, however, with a promise to release it for other groups of users over time. Now, OpenAI co-founder Greg Brockman announced on X that voice conversations on ChatGPT have started to expand for all users on mobile devices, including non-paying users.

When the company first introduced voice conversations, it admitted that the ability to create realistic synthetic voices from just a few seconds of real speech presented new risks. For example, it could allow unauthorized persons to impersonate public figures or anyone else. As a result, it was decided that the voice function of ChatGPT focus on conversations. It is model driven text to speechwhich can generate human-like sound only from the text and a few seconds of sample speech. OpenAI worked with voice actors to create this feature and offers a choice five different voices.

However, not all users have access to the new function. It’s possible, that it will take some time to be made available to everyoneat the same time it is not entirely clear, whether users must log in to it (paid subscribers had to enable it by going to Settings and then the New Features section after voice conversations were introduced).

Brockman announced the release of the position after leaving his position as president of OpenAI. He left voluntarily after the company’s board removed Sam Altman as CEO. Shortly after his announcement, OpenAI confirmed that Altman and Brockman had been reappointed and would return to their original positions.
