With "show emoji in call" enabled, voice mode stayed completely silent and no request ever reached the configured TTS server. Reasoning models served with a reasoning parser return `message.content` as null and put the text in `reasoning_content`, and the emoji helper called `.replace()` on that null value and threw.
The call overlay ran the emoji request first, inside the same `try` block as speech synthesis, so that error skipped the entire TTS section. The audio cache was never filled, and the playback loop kept re-queueing the same content every 200 ms without ever playing it. Read aloud was unaffected because it synthesizes speech directly, which is why the failure looked specific to voice mode.
Fixed on both sides: the optional chain in `generateEmoji` now covers `content`, and the emoji request in the call overlay gets its own catch, matching the speech synthesis call directly below it. An emoji failure now costs the emoji instead of the whole reply.
Every toggle row in the chat integrations menu (filters, Web Search, Image, Code Interpreter, Tools, Skills) is a button whose on/off state was carried only by the decorative Switch inside it. Screen readers announced the row name and nothing else, so there was no way to tell whether a tool or feature was active without looking at it.
Each row button now carries aria-pressed, and the Switch wrapper is marked inert so the nested role=switch stops competing with the row for the announcement and stops adding a nameless tab stop. Hit testing skips inert content, so clicking the switch still toggles the row.
Tool rows that are not yet authenticated omit aria-pressed: activating those starts an OAuth redirect rather than toggling, so announcing them as an unpressed toggle would be wrong.
The Web Search, Image and Code Interpreter rows also had a state-flipping aria-label ("Disable Web Search") on top of aria-pressed, which announces as "Disable Web Search, pressed" and reads as the opposite of the truth. Removed: the visible row text already names each control.

The VoiceRecording component stays mounted (hidden) between recordings, and the web speech engine accumulated every session's transcript into the never-reset transcription variable. Each new recording therefore confirmed all previous utterances again, so the inserted text repeated once per session and previously deleted text reappeared in the input.
Additionally, cancelling a recording (X button, Escape or a recognition error) called stopRecording(), which stops the SpeechRecognition instance and fires its onend handler, which unconditionally confirms the transcription. Cancelled recordings therefore still inserted the accumulated transcript.
Reset the transcription at the start of each web speech session and detach the onend handler on cancel so cancelled recordings no longer confirm.
