You can talk to your ClawBox now - #410
Conversation
Voice input for device chat: a microphone button in the mascot composer, a
recording that the box turns into text, and the text dropped in the input for
you to read before you send it.
Deliberately not send-on-stop. Transcription gets words wrong, and a chat that
fires off a misheard sentence before you can look at it is worse than no
dictation at all. Dictation is also additive — someone who typed half a
sentence and then spoke the rest ends up with both, because there is no undo in
a chat composer and replacing the box would destroy typed text silently.
The box proxies the recording rather than letting the browser call out. The
ClawBox AI token in ~/.openclaw/openclaw.json is the device's credential; handed
to page JavaScript it would sit in every devtools network panel and in the
memory of any script the chat surface loads. So the browser talks to the box and
only the box talks to the proxy. For the same reason an upstream error body
never crosses back: proxies commonly quote the failing request, and that request
carried the bearer token, so only the status is relayed.
Model is gpt-4o-mini-transcribe at $0.003/minute — the cheapest of OpenAI's
eight transcription options, half of Whisper's, a sixth of gpt-live-transcribe.
About $0.18 for an hour of dictation a month. Sending no model at all would
leave the proxy's default deciding what a minute costs.
Verified against the live ClawBox AI proxy before any of this was written:
POST /audio/transcriptions takes multipart with a `file` part and returns
{ text }, and it accepts WebM/Opus — which is exactly what Chrome's
MediaRecorder produces — so the box re-encodes nothing. WAV works too; the
format list exists for other browsers, since Safari has no WebM and answers with
MP4/AAC.
Every state is one the composer can render, and every one of them is rendered:
waiting for permission, recording with a live dot and an elapsed clock, cancel,
transcribing, and errors split by what the user should actually do about them —
a refused permission is fixed in site settings, a missing device is not.
Releasing the microphone is tied to leaving the recording state rather than to
any one button, so finishing, cancelling, erroring, closing the panel and
unmounting all release it. A capture running while the interface looks idle is
the one outcome this must never produce.
A failed transcription keeps the audio and offers Retry, because most failures
here are a flaky uplink rather than a bad recording. A recording that captured
nothing says so instead of spending a proxy call to be told there is no speech.
An empty transcript is a successful call that heard silence — reported as such,
not as an error, or the user re-records to fix a working feature.
The privacy line is on the surface where it happens, not only in a settings page
nobody opens: voice input sends your recording to ClawBox AI, and it leaves the
box. Error text is whitelisted by shape before display — anything holding a
path, URL, token or stack frame is dropped for a generic line instead.
Strings in all ten locales. 230 files / 3106 tests green, up from 228 / 3065.

Review round 1 on the voice-input PR. Eight findings, all of them real. The one that could actually cost a customer their words: MediaRecorder buffers until it is stopped, and the route only discovers an oversized blob after the entire upload has finished — so a capture left running paid for the upload and then lost the dictation to a 413. A recording now finishes itself at ten minutes through the same stop path the button uses, so it is transcribed rather than thrown away. The one that could cost the box: nothing bounded the request body. There is no reverse proxy in front of this route trimming bodies, and formData() will not say how big a part is until the whole body is in memory, so the size check fired only after the memory had been spent. The bytes are now counted as they arrive and the stream is cut off past 26 MB; Content-Length is honoured when offered but not believed, because a chunked body declares nothing. The rest: a retry is no longer offered for a transcript that came back empty (the call succeeded, so re-sending the same bytes buys the same silence and one more paid transcription); the multipart parser's own wording stays in the box's log instead of the user's status line; the voice status row is a polite live region, because a pulsing dot and a running clock are not signals a screen reader can see; the dismiss button says dismiss rather than borrowing the preview label; the keyframes name is kebab-case, which is what Stylelint has always required here; and the route test derives the provider key from CLAWBOX_AI_PROVIDER so a rename fails as a rename. 233 files / 3116 tests green.
Hardware proof on .65 found the mic button dead for a second reason, and this one is ours: every page the box serves carries `Permissions-Policy: camera=(), microphone=(), geolocation=()`. An empty allowlist is not "ask the user" — it is off. The document itself may not use the feature, so getUserMedia answers NotAllowedError before anyone is prompted, in a secure context, with the permission already granted at browser level. Measured through the box's own Cloudflare tunnel, where isSecureContext is true and mediaDevices, getUserMedia and MediaRecorder are all present: the call still failed with "Permission denied", and the composer correctly said ClawBox needs microphone access — on a box where nothing had denied it. `microphone=(self)` restores it for this origin and nothing wider. A cross-origin frame still gets no microphone: that needs the embedder to delegate with allow= AND this list to name it, and it does not. Camera and geolocation stay off; nothing in the UI asks for them. The test reads the real next.config so re-tightening the header fails loudly instead of quietly returning the button to a state where its only possible outcome is an error message.

Making the voice status a live region is right -- the pulsing dot and the running clock are the only sign the microphone opened, and a screen reader sees neither. But `role="status"` is implicitly atomic, so a live region re-announces all of its text on any change inside it, and the elapsed time was in the same text node as the label. The row would be read out in full once a second for as long as the capture ran: with the ten-minute cap added alongside it, ten minutes of a screen reader talking over everything else. The clock moves into its own `aria-hidden` node -- out of the accessibility tree, not off the page. Its ticking is then not a change the tree can see, so the announcement fires on what a listener actually needs: that recording started, that it is being transcribed, that it failed. Two smaller things found with it. The ten-minute deadline called `stopRecording` blind, which clears the cancelled flag; `stop()` goes inactive at once but delivers its events in a later task, so a deadline firing between the user's Cancel and those events would have uploaded -- and paid to transcribe -- audio the user had thrown away. And the deadline test pinned the clock to `0:30` under `shouldAdvanceTime`, which also moves the mocked clock with wall time, so it raced the machine; it now asserts on the number of distinct readings, which drift can only ever increase.

Acceptance 4-5 on the voice task: a spoken reply has to be something the user can play. It was not. Measured on box .65: TTS does not use the MEDIA: line a generated picture uses. The harness answers the turn, then appends a SECOND assistant message repeating the same text and carrying the audio as a structured attachment part — url, kind: "audio", mimeType. The chat's extractText reads text parts and nothing else, so the box ran Piper, wrote 92 KB of wav into ~/.openclaw/media/outbound, and rendered a caption with no way to hear it. The model, asked where the file was, answered that TTS "streams audio directly to the channel and produces no file" — it had no idea either. So: attachment parts are read on the live path and on the replay from history, and the repeat is folded into the bubble it belongs to rather than appended, which would have shown every spoken answer twice, once silent. The player is the browser's own `<audio controls>` — play, pause, scrub and duration are exactly what "a normal playable message" means and all of them already work, keyboard included. Keyed by URL so re-rendering a transcript cannot hand one player another's recording. The media route had to change with it. It served images only, so every spoken reply was a 415, and it did not answer Range requests — without which Chrome plays the file but the scrubber will not move and Safari refuses to start it. "Playable with native controls" is a property of this response, not of the element. Ranges are applied after the containment checks, so a Range header cannot become a way to read a file the route would otherwise refuse, and an unsupported range form gets the whole file rather than a 416 that would break playback. Also from review round 2, both real: A MediaRecorder that errors still delivers `dataavailable` and `stop` afterwards. The stop handler would have uploaded the partial audio from a capture the browser had just called failed, paid to transcribe it, and replaced the error the user was reading with a spinner. Handlers are detached and the chunks dropped before the error state is set. `getUserMedia` resolves in a later task than the click, and until it does there is no stream for any cleanup to stop. Closing the panel with the permission prompt open therefore left a live microphone behind an interface that was gone — the one outcome this feature must never produce. The resolver now checks a generation counter, bumped every time the microphone is released, and stops the tracks it was handed instead. 235 files / 3152 tests green. tsc unchanged at 13 pre-existing errors in unrelated suites.

Sensitive Data Exposure (CWE-525): Use of Web Browser Cache Containing Sensitive Information

Split: one of these is fixed, the other is declined.
FIXED — the empty-file suffix range. bytes=-4 against a zero-byte file produced Content-Range: bytes 0--1/0, which is not a range. parseRange now returns null for size === 0 on the suffix form, so the whole (empty) file is served, with a test.
DECLINED — no-store. This would reverse a deliberate, documented decision on a path that already shipped, and pay for it in bandwidth on the hardware least able to spare it.
The header is not new to audio; every generated image has been served under private, max-age=31536000, immutable since the image work, and the reason is in the source: the harness names every file with a UUID and never rewrites one, so without immutable reopening a chat re-reads and re-transfers every picture in the visible history once an hour. On a Jetson Orin Nano serving its own UI, that is real.
On the identity argument: this is a single-owner appliance, not a multi-tenant application. There is one operating-system user, one browser profile in normal use, and the cache in question is the owner reading back their own conversation on their own device. The route is session-gated for the network case; the browser cache is not the boundary being defended.
If a re-link to a different owner should purge previously fetched media, that is a real requirement — but it belongs to the device-handover story as a whole (transcripts, generated images, ClawKeep index), not to a Cache-Control header on one route, and switching this one to no-store would give the appearance of solving it without doing so.

@yalexx, the shell result does not show the stated range fix on the inspected branch.
parseRange("bytes=-4", 0) still returns { start: 0, end: -1 }. The GET() handler then emits an invalid Content-Range: bytes 0--1/0. The focused test output also does not include a zero-byte suffix-range test.
I withdraw the no-store request. The established immutable cache policy is intentional for this single-owner device model. The zero-byte suffix-range defect remains open.

Support .webm audio files.
AUDIO_EXT_RE accepts .weba but rejects .webm. A structured audio attachment with a .webm URL therefore renders a player whose media route rejects the source with 415, while a MEDIA: directive for the same file is dropped.
Add .webm to this allowlist and to CONTENT_TYPES in src/app/setup-api/chat/media/route.ts. Add .webm cases to src/tests/unit/chat-media.test.ts and src/tests/routes/chat-media.test.ts.

Taken, by the route rather than by the matcher.
You are right about the outcome: an audio attachment whose URL ends .webm rendered a player pointed at a 415. .webm is now in the media route's type map as audio/webm, with a test.
AUDIO_EXT_RE is deliberately left without it. .webm is genuinely ambiguous — it is a container, and a video in it is the commoner thing on the open web. extractAudioAttachments already trusts kind: "audio" and mimeType, which is how a real spoken reply identifies itself, so nothing is lost there; teaching the extension test to claim .webm would instead route a bare MEDIA:/…/clip.webm naming a video into an <audio> element, where it would play the soundtrack of a picture nobody can see.

@yalexx, the matcher rationale is valid. Keep .webm out of AUDIO_EXT_RE.
However, the current branch does not contain the route change. CONTENT_TYPES includes only .weba: "audio/webm" at Line 54. The route test includes only v.weba at Line 183.
Please add .webm: "audio/webm" to CONTENT_TYPES and a .webm route test. This change fixes playback for structured attachments that identify the file as audio.

Learning: In `src/lib/chat-media.ts`, `.webm` must remain excluded from `AUDIO_EXT_RE` because extension-only detection cannot distinguish WebM audio from WebM video. `extractAudioAttachments` identifies structured WebM audio through `attachment.kind === "audio"` or an `attachment.mimeType` that starts with `audio/`; the extension test is only a fallback.

Deploying the player was not enough: on a real box it never appeared. Captured every websocket frame of a TTS turn on .65 to find out why. The audio does reach the browser — as a `session.message` event carrying the assistant-media message with its attachment intact. The `chat` stream never carries it, and the chat surface was only reading `chat` events and the history replay. So it was rendering a reply whose sound had been pushed to it and thrown away. Read off that event now, folded into the bubble whose text it repeats. The reconcile that same event schedules had to be taught to keep it. It re-reads `chat.history` 400ms later and rebuilds the transcript from the answer — and that answer does not contain the attachment: 16 messages back, not one with a `"type":"attachment"` part, while the session file on disk has it. Without carrying it across, the player appeared and then vanished half a second later, which reads as a flicker rather than a bug. That gap is the refresh half of acceptance 5 and it is NOT fixed here: after a reload there is nothing on the wire to render. The client side is ready — the history path reads attachments and there is a test for it — but the data would have to come from an OpenClaw gateway change, outside this repository. Recorded on TASK-381 as a blocker rather than waived, and the test that covers it says plainly that it proves the renderer and not the box. 235 files / 3153 tests green.
A player that plays the wrong words. `sameTranscript` compared audio counts, not URLs, so a reply whose recording was replaced kept the count and changed the file — React skipped the render and the player stayed pointed at the old one. That failure is audible and convincing, which makes it worse than a blank one. An error nobody asked for. The generation check that stops a microphone arriving after the panel closes was only on the success path. A prompt still open when the panel closes can be DENIED afterwards, and that error was pinned to a panel nobody was looking at — still there the next time the chat opened, describing a request that was no longer anyone's. A range that is not a range. `bytes=-4` against an empty file answered `Content-Range: bytes 0--1/0`. The whole (empty) file is the honest reply. A player pointed at a 415. `.webm` is now served as `audio/webm`. It is deliberately not added to the extension test: `.webm` is a container and a video in it is the commoner thing, so a bare `MEDIA:` line naming one would have been routed into an `<audio>` element. A real spoken reply identifies itself by `kind` and `mimeType`, which is already trusted. A wildcard the matcher could not see. The Permissions-Policy test rejected `microphone=*` — a string that appears in neither `microphone=(*)` nor `microphone=(self *)`, both of which hand the microphone to every embedder. And a lint error: `socket = this` in the test harness trips no-this-alias. Declined, with reasons on the threads: `Cache-Control: no-store` on the media route (it would reverse a documented decision on a path that already shipped and re-transfer every image in a chat once an hour on a Jetson; the box is a single-owner appliance and the browser cache is not the boundary being defended), and "keep this blocked until the device serves HTTPS" (the header was measured to be the blocker AFTER the secure-context one was solved — over the tunnel, permission granted, APIs present, and getUserMedia still refused). 235 files / 3156 tests green. eslint clean on every changed file. tsc unchanged at 13 pre-existing errors in unrelated suites.
2 participants
Voice input for device chat — TASK-381, part of the V4 epic (TASK-379).
A microphone button in the mascot chat composer, a recording the box turns into text, and the text dropped into the input for you to read before you send it.
What this covers, and what it does not
Acceptance items 1, 2, 3 and 6 — the mic button, the full set of recording states, a real English recording reaching the configured STT path and producing usable text, and the privacy/no-leakage requirements.
Items 4 and 5 — OpenClaw TTS replies rendering as playable audio messages with native controls, surviving refresh and reboot — are not in this PR. They are a different surface (assistant message rendering, not the composer) and nothing in the repo renders audio in chat today, so they are their own piece of work. Flagging that plainly rather than implying the task is finished.
Decisions worth arguing with
Not send-on-stop. Transcription gets words wrong. A chat that fires off a misheard sentence before you can look at it is worse than no dictation. The transcript lands in the input box; you send it.
Dictation is additive. Typed half a sentence, then spoke the rest? You get both. Replacing the box would destroy typed text, and a chat composer has no undo.
The box proxies; the browser never calls out. The ClawBox AI token is the device's credential. In page JavaScript it would sit in every devtools network panel and in the memory of any script the chat surface loads. Same reasoning drives the error handling: upstream bodies are never relayed, only statuses, because proxies commonly quote the failing request — and that request carried the bearer token.
gpt-4o-mini-transcribe, explicitly. $0.003/minute, the cheapest of OpenAI's eight transcription options: half of Whisper's $0.006 and a sixth ofgpt-live-transcribe. About $0.18 for an hour of dictation a month. Sending no model at all would leave the proxy's default deciding what a minute costs.Verified before it was built, not after
POST https://clawbox.com/api/ai/audio/transcriptionson the live proxy, from a real box: takes multipart with afilepart, returns{ text }, and accepts WebM/Opus — exactly what Chrome'sMediaRecorderproduces — so the box re-encodes nothing. WAV works too. The format list exists for other browsers, since Safari has no WebM and answers with MP4/AAC.The microphone is never live invisibly
Releasing the capture is tied to leaving the recording state, not to any one button, so finishing, cancelling, erroring, closing the panel and unmounting all release it. Recording always renders a live dot and an elapsed clock. That is the one outcome this feature must never produce, so it is enforced structurally rather than per-handler.
Errors are split by what the user should actually do: a refused permission is fixed in site settings, a missing capture device is not. A failed transcription keeps the audio and offers Retry, since most failures here are a flaky uplink rather than a bad recording. A recording that captured nothing says so instead of spending a proxy call to be told there is no speech. An empty transcript is a successful call that heard silence — reported as such, or the user re-records to fix a working feature.
Leakage
The privacy line sits on the surface where it happens, not only in a settings page nobody opens. Error text is whitelisted by shape before it is displayed: anything holding a path, a URL, a token or a stack frame is dropped for a generic line.
Tests
230 files / 3106 tests green, up from 228 / 3065. Strings in all ten locales. The route tests drive the real route with a stubbed upstream and cover the credential handling, the not-linked case, the size and empty guards, every upstream failure mode, and the token-echo case specifically.
