📝 WalkthroughWalkthroughThis change adds on-device voice dictation for macOS. It includes settings, shortcut handling, authorization, platform-specific transcription engines, focused-target insertion, a dictation HUD, localization, privacy metadata, documentation, and automated tests. ChangesVoice dictation
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The new voice dictation path can currently produce corrupted text, mishandle quoted or non-space-writing languages, and overlap cleanup with a subsequent dictation session; audio-buffer reuse may also degrade transcription. These correctness issues should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Full details: Description checkExplanation The description is detailed and directly covers the feature, architecture, testing, manual verification, privacy behavior, documentation, and known scope cuts. It omits the template checklist and a demo video link or attachment, but the core required change and testing information are complete. Full details: Cmux Swift Actor IsolationExplanation No changed production declaration matches the failure conditions. The new CmuxVoice value models and service protocols are in Swift 6 package targets without a MainActor default; they are Sendable and not implicitly MainActor-isolated. Speech engines are actors. The shared unchecked-Sendable audio helpers have documented lock or single-worker ownership. UI-bound types and stores use explicit Full details: Cmux Swift Blocking RuntimeExplanation PASS — The production diff adds no semaphore, blocking wait, Full details: Cmux Browser Automation Off-MainExplanation PASS: The pull request does not change cmux browser socket automation routing. Against merge base Full details: Cmux Expensive Synchronous LoadExplanation PASS: The pull request adds voice-dictation state, UI, speech engines, insertion routing, and shortcut wiring, but it does not add or move any expensive agent-history loader. The added production Swift lines contain no Full details: Cmux Cache Substitution CorrectnessExplanation PASS — The PR does not replace a fresh authoritative read with a cached or opportunistic value in a persistence, history, undo, or persisted snapshot path. The diff from merge base Full details: Cmux No Hacky SleepsExplanation PASS: The changed non-Swift files contain only shortcut metadata, schema data, and Xcode/workspace wiring. The added lines introduce no sleep, timer, polling, fixed backoff, delayed dispatch, or wall-clock synchronization. The workflow change is explicitly out of scope, and the voice runtime implementation is Swift. Full details: Cmux Algorithmic ComplexityExplanation PASS. The changed production paths do not introduce a prohibited scalable-collection algorithm. Voice language loading performs one linear filter/map and one sort in a Full details: Cmux Swift ConcurrencyExplanation PASS — The diff uses Swift concurrency for cmux-owned async work. Full details: Cmux Swift `@Concurrent`Explanation No custom-check failure found. The new nonisolated language-list helper is explicitly Full details: Cmux Swift Package BoundariesExplanation PASS — The diff places the reusable dictation state machine, protocols, transcript logic, route resolver, authorization, and speech engines in the new Full details: Cmux Swiftpm LockfilesExplanation The PR adds the local Resolution Regenerate the root Xcode SwiftPM resolution after adding the Full details: Cmux Swift LoggingExplanation The PR adds no Full details: Cmux User-Facing Error PrivacyExplanation PASS. The changed user-facing alerts and recovery text use generic cmux terms such as microphone access, speech recognition, model download, and try again. Locale text displays only the selected locale identifier. Upstream error details are passed to the coordinator only for logging with Full details: Cmux Full InternationalizationExplanation The PR adds production voice UI copy through localized Swift APIs, but its catalog coverage is incomplete.

Resolution Keep Full details: Cmux Swift Auxiliary Window Close ShortcutsExplanation PASS. The PR adds one standalone user-visible window: Full details: Cmux Source ArtifactsExplanation PASS — The diff against origin/main contains 51 intentional product paths: Swift sources, tests, a Swift package manifest and README, app/build configuration, CI configuration, localization catalogs, and documentation. No changed path uses the prohibited scratch or artifact directories, and the diff contains no binary files or local tool output. The CmuxVoice package and its tests are deliberate product and test-system additions. Full details: Cmux No Test Or Debug Seam In Production SourceExplanation No prohibited test/debug seam was added to changed production Swift sources. The PR diff adds no DEBUG, XCTest, TESTING, or similar build guards, and no member names matching the rule’s debug/test patterns.

Inline comments:
In `@docs/configuration.md`:
- Line 275: The Voice dictation documentation currently says finalized text is
entered into the “focused pane,” but the implementation uses the pinned
insertion target. Update the sentence in the Voice settings description to refer
to the pinned target captured by dictation, while preserving the existing
on-device processing and language-selection details.
In
`@Packages/macOS/CmuxSettingsUI/Sources/CmuxSettingsUI/Sections/VoiceSection.swift`:
- Around line 74-83: Mark the pure value-model struct
VoiceDictationLanguageChoice as nonisolated, and annotate its async
systemChoices() method with `@concurrent` so the language lookup runs off the
caller’s actor while preserving the existing API and sorting behavior.
In `@Packages/macOS/CmuxVoice/Sources/CmuxVoice/DictationController.swift`:
- Line 1: Track insertion-session state in DictationController with a
hasBegunInsertionSession flag set only when inserter.beginSession() returns
true, and have settle() and fail() call inserter.endSession() only when that
flag is set. Extend microphoneDenialFailsWithoutStartingEngine and
missingInsertionTargetFails to assert inserter.ended == 0.
- Around line 149-153: Update the trailing flush in handle so it checks the
Boolean result of inserter.insertFinalizedText(delta), matching the existing
failure handling used for normal finalized text. If insertion fails, fail or
terminate the session through the established error path and do not call settle
as a successful completion; only settle after the trailing text is inserted
successfully or when there is no delta.
In
`@Packages/macOS/CmuxVoice/Sources/CmuxVoice/SpeechAnalyzerDictationTranscriber.swift`:
- Around line 236-255: Update handleConfigurationChange() to handle failures
from startAudioEngine() instead of discarding them with try?. If re-arming the
engine fails after an AVAudioEngineConfigurationChange notification, finish the
active dictation stream with DictationFailure.audioCaptureFailed; preserve the
existing restart flow when startup succeeds.
In `@Resources/Info.plist`:
- Around line 78-80: Add the NSSpeechRecognitionUsageDescription localization
entry to Resources/InfoPlist.xcstrings, matching the existing localized
structure and the usage description from Resources/Info.plist. Preserve the
existing NSMicrophoneUsageDescription entries and provide translations for all
supported locales so the speech-recognition prompt does not fall back to
English.
In `@Sources/AppDelegateVoiceDictation.swift`:
- Around line 17-33: Remove the final tabManager fallback from
voiceDictationFocusedTerminalPanel(). Return nil whenever NSApp.keyWindow is
absent or neither key-window resolution path finds a focused terminal panel, so
dictation fails closed for non-main or unresolved windows.
In `@Sources/Voice/VoiceDictationCoordinator.swift`:
- Around line 127-151: Update the .modelDownloadFailed, .audioCaptureFailed, and
.transcriptionFailed branches in VoiceDictationCoordinator so presentInfoAlert
uses localized product-level informative copy instead of displaying the raw
detail value. Preserve the existing localized titles, and route the underlying
detail/error to logging rather than exposing it in the user-facing alert.
In `@Sources/Voice/VoiceDictationInsertionRouter.swift`:
- Around line 62-68: Update the webViewEditable branch in
DictationController.handle(_:generation:) to propagate evaluateJavaScript
failures through the inserter protocol instead of unconditionally returning
true. Handle the asynchronous completion error, report failure to the caller,
and preserve the existing guard behavior so DictationController can fail closed
and end the session consistently with the other insertion branches.

17-27: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winRemove the
tabManagerfallback for absent key windows to ensure dictation fails closed.While the fallback for non-main windows was fixed, dictation still falls back to the global
tabManagerifNSApp.keyWindowisnil(e.g., when the app is in the background or no window is active). This acts as an unreliable fallback that can unintentionally route dictated text into a background terminal window.As per path instructions, dictation routing must rely on a single authoritative source and must fail closed when reliable signals are missing, rather than adding an "unreliable but better than nothing" fallback branch.

63-78: 🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy liftWeb-view insertion failures on the final segment are silently dropped.
While using
webViewInsertionBrokenprevents subsequent segments from being dropped, it does not prevent the current segment from being silently dropped if it happens to be the last one in the session. For instance, if the trailing flush fails,insertFinalizedTexteagerly returnstrue, and the controller transitions to.idle(success) without showing an error or inserting the text.To reliably fix the silent text dropping issue, consider changing the
DictationTextInsertingprotocol (inDictationTextInserting.swift) to add an asynchronous failure callback (e.g.,var onAsyncInsertionFailure: (() -> Void)? { get set }) that the controller can observe. The controller could then explicitly fail the session when the callback fires, even if the method initially returnedtrue.🤖 Prompt for AI Agents

- Around line 12458-12461: Add the root SwiftPM lockfile at the workspace’s
shared SwiftPM location and include the required Package.resolved diff alongside
the XCLocalSwiftPackageReference for CmuxVoice, preserving the lockfile’s valid
package-resolution format.
In `@Packages/macOS/CmuxVoice/Sources/CmuxVoice/DictationController.swift`:
- Around line 253-266: Replace the fixed-delay logic in armStopWatchdog with a
session-owned shutdown operation that completes only on the transcription
engine’s explicit completion or stream-termination signal. Remove the
Task.sleep-based timeout path, sessionTask cancellation, finishTranscribing
trigger, and fail call so final segments and partial results remain consumable
until finalization completes.

- Around line 78-92: Update commit(_:) and needsSeparator(before:) in
DictationTranscript.swift to use a locale- or script-aware separator policy, or
preserve engine-provided boundaries, so adjacent non-space-language segments do
not receive an ASCII space while normal word boundaries remain separated. Add

Build on #8043's on-device dictation: - Insert through the terminal paste path instead of typed keys. - Live level meter in the HUD, fed outside the transcript stream. - Opt-in OpenAI cloud engine using the user's own key from the Keychain. - Hold-to-talk or toggle shortcut modes. - Mic button in the surface tab bar and a command palette entry. - Optional filler cleanup for agent prompts. - Fixture engine for UI tests and a dogfood tour. - Localized in all nine app locales.

Picked this up in #15252 on current main, with you as co-author on the commit. It keeps the CmuxVoice package and the on-device engines, and adds paste-path insertion, a level meter, a tab bar mic, hold-to-talk and an opt-in OpenAI engine. I'll close this once #15252 lands. Thanks for the solid base :) |
Main's grouped Settings sidebar landed after #8043, so the Voice section had no sidebar entry. Put it under Agents & Automation, and have the dogfood tour open it. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Superseded by #15252, which carries the voice-dictation feature forward on current main with the original routing/tests plus the completed UI and engine work. Closing the older branch. |

Adds cmux voice: press a shortcut (default ⌃⌘V), speak, and cmux types what you say into the focused pane. Everything runs on-device — no audio or transcripts ever leave the machine.

Thecom.apple.security.device.audio-inputentitlement was already present in release/nightly signing.Engine choice and deployment-target reasoning
The app's minimum is macOS 14.0 (app target and all packages), so the new API cannot be used unconditionally:
SpeechAnalyzerDictationTranscriber: the SpeechAnalyzer / SpeechTranscriber family with.volatileResults, managed model assets viaAssetInventory(assetInstallationRequest(supporting:).downloadAndInstall()surfaces as the HUD's "Preparing…" phase),bestAvailableAudioFormat+AVAudioConverterfeedingAnalyzerInputs from anAVAudioEnginetap, andfinalizeAndFinishThroughEndOfInput()on stop.SFSpeechDictationTranscriber:SFSpeechRecognizerwithrequiresOnDeviceRecognition = truealways. If a language has no on-device support the session fails with guidance — cmux never falls back to server recognition.SFSpeechRecognizerfinalizes per utterance, so the engine chains recognition cycles behind one continuous event stream.The choice is per-OS, never per-session (no silent degradation to the legacy engine on macOS 26). Both engines handle
AVAudioEngineConfigurationChange(input device unplugged / default input switched) by re-installing the tap instead of crashing, and both flush the trailing hypothesis on stop.Privacy
All recognition is on-device.
requiresOnDeviceRecognitionis hard-coded on the legacy path; SpeechAnalyzer is on-device by design. No audio, partial, or final transcript is written to disk or sent anywhere. User-facing copy (setup dialog, settings subtitle, Info.plist usage strings, docs) states this explicitly.Architecture
New Swift package
Packages/macOS/CmuxVoice(linked intocmux+cmux-unit, added to the CIswift testpackage list):DictationController—@MainActor @Observable, owns the session lifecycle (idle → requestingAuthorization → preparing → listening → stopping → idle,failedas a resting error state) with constructor-injected seams (DictationAuthorizing,SpeechTranscribingfactory,DictationTextInserting, locale provider).DictationTranscript— pure value type folding partial/final events into committed text + volatile tail.SpeechTranscribingprotocol; audio-thread tap → engine handoff uses the repo's documented lock carve-out (OSAllocatedUnfairLockguarding a single reference, with justification comments).App target adds only new files under

No fake coverage is claimed for it.Manual verification steps (needs a mic)
Localization audit
All new user-facing strings (shortcut label, Settings section/rows, HUD, setup dialog, error alerts, search aliases) use
String(localized:defaultValue:)with en + ja entries added toResources/Localizable.xcstrings(29 keys, validated JSON). The web shortcut catalog entry carries inline{en, ja}descriptions.

Medium Risk
New microphone/speech permissions, real-time audio capture, and text insertion into terminals and web views; mitigated by on-device-only recognition, pin-at-start routing, and extensive deterministic tests.
Overview
Introduces on-device voice dictation: users toggle dictation with a new app shortcut (default ⌃⌘V), speak, and finalized transcript segments are typed into the pane that had focus when the session started.
The work adds the
CmuxVoiceSwift package (DictationControllersession lifecycle, transcript/commit model, macOS 26 SpeechAnalyzer vs 14–25 SFSpeech on-device engines, insertion routing) plus Settings › Voice (enable + language),toggleVoiceDictationin the shortcut system, and app wiring so the shortcut only runs when dictation is enabled. Legacy shortcut resolution suppresses the new default when an older explicit binding already owns that chord; a small cached lookup avoids scanning bindings on every key event.Also updates microphone / speech-recognition usage strings, localization for HUD/errors/setup copy, CI (
CmuxVoiceinswift test, determinism allowlist lines), and unit tests for the state machine, transcript spacing, and shortcut upgrade behavior.Reviewed by Cursor Bugbot for commit 77fa824. Bugbot is set up for automated code reviews on this repo. Configure here.
