Talk client UI

macOS UI

• Menu bar: Voice & Talk Settings… opens the native Voice & Talk settings page.
• Native settings: Use realtime Gateway relay is a local, default-off opt-in for this Mac.
• Open in Dashboard hands provider, model, voice, and transport setup to Control UI Settings → Talk under Connections.
• Menu bar: Talk Mode starts or stops the current Talk session.
• Overlay: the orb renders the universal talk waveform (shared with iOS, watchOS, and Android). Listening follows the live mic level, Speaking follows the actual TTS playback envelope, Thinking breathes softly. Click the orb to pause/resume, double-click to stop speaking, click X to exit Talk mode.

Apple Watch UI

Tap Connect Apple Watch in iPhone Settings → Apple Watch, then open Talk on Watch and tap Start. Voice is included without a separate enable setting; setup alone does not activate the microphone. The Watch asks you to choose an agent when more than one is available, creates a separate chat for the call, and shows the latest speech transcripts with Mute and End controls. It does not run the agent or stock Codex runtime locally.

Keep the app in the foreground until connected. Established calls use background audio; an unfinished startup stops if backgrounded. Physical wrist-down, speaker routing, cellular handoff, and long-call endurance remain unverified. Simulator results and macOS provider-audio probes are not proof of Watch background behavior. See Watch setup and limits.

Android UI

• Android's main navigation is Home, Chat, and Settings. Voice input lives in the Chat composer rather than a separate Voice tab.
• Tap the composer microphone for on-device dictation. Long-press it to record a voice-note attachment. Start continuous Talk from the Talk waveform.
• Dictation, voice-note recording, and Talk are mutually exclusive microphone paths; starting one stops or blocks the others.
• Realtime Talk prefers a connected Bluetooth Classic or BLE headset microphone; if it disconnects, the app requests another headset input or falls back to the default microphone, restoring the default preference once capture stops.
• Realtime Talk requests Android communication mode and audio focus, using a connected external output or the built-in speaker. Microphone audio is sent during playback only while acoustic echo cancellation is enabled and the communication mode and focus remain active. Without echo cancellation, microphone audio is not sent during playback. Android presentation timestamps estimate playback completion when available. Routes without usable timestamps use approximate playback position plus the nominal PCM duration; this cannot guarantee that all acoustic output has drained on every device.
• Losing audio focus or encountering a playback-device failure ends realtime Talk with an error. Interruption clears queued output before capture resumes; stopped sessions cannot acknowledge playback through a replacement Gateway.
• Realtime Thinking follows provider response generation or an accepted OpenClaw consult, not input transcription, which may finish after the answer. Direct replies without a provider or Gateway response-start signal stay Listening until output arrives. Empty completed responses return to Listening; buffered audio stays Speaking until playback drains.
• Dictation and voice-note recording stop when the app leaves the foreground or the user leaves Chat.
• Talk Mode keeps running until toggled off or the node disconnects, using Android's microphone foreground-service type while active.
• Android supports pcm_16000, pcm_22050, pcm_24000, and pcm_44100 output formats for low-latency AudioTrack streaming.
