Missing end-conversation, microphone, and speaker controls in Voice Mode on iOS

Summary

On the iOS ChatGPT app, the button to start a Voice Mode conversation is present. However, an active Voice Mode session does not show controls to:

• end the conversation;
• mute or unmute the microphone;
• mute or unmute the speaker.

Without these controls, the user cannot explicitly close the voice session or manage microphone and audio output during it.

Test environment

• iOS 27.0
• ChatGPT mobile app 1.2026.202

Expected behavior

An active Voice Mode session should provide visible and accessible controls to end the conversation, mute or unmute the microphone, and mute or unmute the speaker.

Actual behavior

All of these controls are missing.
