Why does my account still doesn't have the speech option on the web interface?

Not sure why I still don’t have the speech option for my account:

Apparently the speech feature has been there since March? Has it been rolled out completely to all accounts?

The same thing happens to me, I have an account that I created when ChatGPT came out that if it has Speech but it does not have Explore GPT, then create a new ChatGPT account, in this new one I do have Explore GPT but Speech no longer appears. For what is this?
