Show a visible processing state while voice transcription is in progress

What version of the Codex App are you using (From “About Codex” dialog)?

Not captured; the issue has occurred in recent Codex Desktop versions.

What subscription do you have?

Not specified.

What platform is your computer?

macOS

What issue are you seeing?

When I use voice-to-text in Codex Desktop and press Stop or Send, the relevant control becomes disabled while the recording is being transcribed. However, there is no clear visual status indicating that transcription is still in progress.

This makes it difficult to tell whether Codex is actively processing the audio, has failed, or is stuck. The ambiguity is especially frustrating when transcription is slow or unreliable: I do not know whether I should keep waiting, retry, or take another action.

What steps can reproduce the bug?

1. Start a voice recording in the Codex Desktop prompt composer.
2. Speak a prompt.
3. Press Stop or Send.
4. Observe that the control becomes disabled while transcription is processed.
5. Notice that there is no explicit Transcribing… status, spinner, progress indicator, or actionable failure state.

What is the expected behavior?

Codex should show an explicit processing state after the recording stops, for example:

• a spinner or other activity indicator;

The state should make it unambiguous whether transcription is still running, succeeded, or failed.

Additional information

This is primarily a UX and state-feedback issue. A disabled control alone does not communicate what the application is doing or whether the user should continue waiting.
