Problem

On iOS, T3 Code dictates with Apple's on-device SpeechAnalyzer. On macOS, the desktop app can only transcribe through a downloaded environment model or a cloud provider, although macOS 26 or later has the same Apple speech engine.

Change

Adds On this Mac → Apple Speech as a per-device destination in Settings → Voice → Transcribe with, in the macOS desktop app only.

• native/apple-speech/AppleSpeech.swift: a CLI helper adapted from the mobile Apple transcription code (@react-native-ai/apple plus this repo's patch), with available, prepare <locale> and transcribe <locale> <wav> commands. It writes JSON to stdout and uses exit codes for unsupported language and unavailable.
• apps/desktop/scripts/build-apple-speech.mjs: compiles it with xcrun swiftc (a universal binary through lipo). Packaging stages it into Resources/apple-speech the same way as the Linux browser-secret helper, and fails if it cannot build it. Dev builds without Xcode 26 skip it, and the option does not show.
• apps/desktop/src/speech/AppleSpeech.ts: the main-process service. It writes the 16 kHz PCM to a temporary 16-bit WAV, runs the helper with timeouts, and maps the result. Three IPC channels are exposed as the optional desktopBridge.appleSpeech.
• Web: a device destination that exists only in the web consent/destination state, not in the shared contract, so the server, mobile and the environment model lists do not change. Transcript cleanup still works. Silence filtering, filler-word removal and custom words still apply only to environment and cloud transcription.
• Info.plist gets NSSpeechRecognitionUsageDescription, in case macOS asks for that permission.
• User docs (voice input, FAQ, composer) and one paragraph in the internal voice-input doc.

Scope and approval

Proposal for maintainer approval: #34026. Related: #24938.

Verification

• On an Apple Silicon Mac (macOS 27.0.1, Swift 6.4), I compiled the helper as a universal binary with the build script's flags, with no warnings, and ran it on its own:
  • available → exit 0. prepare en-US → {"value":"en-US"}. prepare xx-YY → exit 2 (unsupported language).
  • transcribe on a 4.8 s spoken clip → "Hello from the Mac. This is a test of Apple Speech Transcription and T3 code." A clip with 1.5 s of silence in the middle returned all three sentences.
  • No permission prompt appeared when the helper ran from SSH.
• AppleSpeech.test.ts: how helper output becomes a result, the WAV encoding, and rejection of invalid PCM.
• useEnvironmentSpeechInput.browser.test.tsx: the device destination transcribes through Apple Speech and never through an environment.
• vp run check:changed passes.

In the desktop app on a Mac

Desktop dev app (vp run dev:desktop) on an Apple Silicon Mac, macOS 27.0.1:

• The dev build compiled the helper into native/apple-speech/build/arm64/t3-apple-speech.
• Without the helper, "Transcribe with" shows no "On this Mac" group. With it, "On this Mac → Apple Speech" shows and can be selected.
• Dictation in the composer (speech played through the speakers with say "This is a test of Apple Speech dictation in T3 Code"): the composer showed "This is a test of Apple Speech dictation and T3 code." about 0.5 s after Finish. The trace log shows AppleSpeech.prepare 148 ms and AppleSpeech.transcribe 306 ms, with no errors. macOS showed no speech recognition prompt.
• Long recording: the helper transcribed a 7.5-minute spoken WAV in 8.25 s (Apple M4 Pro), well inside the 5-minute timeout.
• First use of a new language (prepare fr-FR): 14.2 s the first time (asset download), 0.07 s after that.

The environment name in the menus is blurred.

The helper/IPC split is clean, timeouts kill the child through the scope, and keeping device out of the shared contract avoids touching server and mobile. The issues I found are in the main-process service: what it caches and what it does not.

1. Medium: prepare spawns the helper again on every dictation start. apps/desktop/src/speech/AppleSpeech.ts:159-160 runs t3-apple-speech prepare <locale> each time it is called, and createAppleSpeechVoiceInputPlatform calls it from the capture prepare callback (browserVoiceInput.ts:146). The voice controller awaits that before prepareToRecordAsync opens the microphone (controller.ts, transcriber.prepare → recorder.prepareToRecordAsync). Every press of the mic button therefore waits for a process spawn, a Speech framework load, supportedLocale(equivalentTo:) and AssetInventory.status before capture begins, and the first words can be lost. Caching successful results per requested locale in the service (a Map<string, Promise<result>>, or Effect.cachedFunction) would avoid this. Only unavailable and unsupported-locale results would need to bypass the cache.

2. Low: an in-flight first download cannot be cancelled, and it can be started twice. The renderer's abort signal is only checked after prepare resolves. If the person cancels during the first model download (up to PREPARE_TIMEOUT = 10 min) and taps the mic again, a second helper starts another downloadAndInstall while the first is still running. The cache from point 1 also fixes this if the cache stores the in-flight promise rather than only the result.

3. Low: a transient failure leaves Apple Speech unavailable until restart. AppleSpeech.ts:153 wraps run(["available"], 10s) in Effect.cached. run turns a timeout or spawn error into ok: false, so a slow first launch (cold Speech framework, a busy machine at login) caches false for the whole process. The renderer probe in apps/web/src/speech/appleSpeech.ts:9 is also memoized (probe ??=), so the option stays hidden until the app restarts. Caching only a definitive answer would fix it: exit 0 means available and exit 3 means unavailable. A timeout or other failure should allow a retry.

One thing worth confirming before this leaves draft, which I could not check from the diff: packaging now fails on macOS without Xcode 26 (build-apple-speech.mjs treats the build as required when --output is passed). release.yml builds on blacksmith-12vcpu-macos-26, so check that the default Xcode on that image has the macOS 26 SDK. If it doesn't, the desktop release breaks.

Process note: the description already says the full in-app path and the before/after screenshots of the Voice settings option are still to come. Those would be the main evidence once the direction in #34026 is approved.

[RVZO6]

Thanks for the review. All three points are fixed in 9527574:

1. Prepare on every start: prepare keeps one in-flight or successful result per requested locale. Starts after the first one do not spawn the helper.
2. Double download: a second tap during the first download joins the same in-flight prepare, so only one downloadAndInstall runs. A cancel in the renderer still does not stop the download itself. The download continues in the background up to the 10-minute timeout, and the next start uses its result.
3. Transient availability failure: the main process keeps only a definite answer (exit 0 = available, exit 3 or no helper = unavailable). A timeout or other failure is probed again. The renderer re-probes after a false answer when the desktop bridge has Apple Speech, which is cheap because the main process holds the definite answer.

AppleSpeech.test.ts covers both caches: the existing output table now prepares twice and expects one spawn on success and two after a failure, and a new table checks availability caching for exit codes 0, 3 and 1.

Xcode on the release runner: mobile-showcase-screenshots.yml builds the iOS app on the same blacksmith-12vcpu-macos-26 image, and that app compiles the same SpeechAnalyzer APIs from @react-native-ai/apple. So the image's default Xcode has the version-26 SDKs. I also compiled the helper with the build script's flags on a Mac with Xcode for macOS 27 (Swift 6.4), with no warnings.

I will add the full in-app check and the Voice settings screenshots after a maintainer approves the direction in #34026.

[binjamshid]

All three points are fixed at 9527574.

1. Prepare: one cached prepare per locale, shared while it is running and dropped on any non-ok result (AppleSpeech.ts:171-189).
2. Double download: a second start joins the in-flight prepare, so only one downloadAndInstall runs.
3. Availability: only exit 0 or unavailable is kept (AppleSpeech.ts:154-166), and the renderer asks again after a false (appleSpeech.ts:15).

The runner answer covers my Xcode question. Nothing else from me until the in-app check and screenshots.

Walkthrough

The macOS desktop app now builds and packages an Apple Speech helper and exposes availability, locale preparation, and transcription through IPC. Web voice input can select an on-device destination, prepare a locale, and send recorded PCM to Apple Speech.

Changes: Apple Speech transcription

Layer / File(s)	Summary
Native helper and packaging native/apple-speech/AppleSpeech.swift, apps/desktop/scripts/build-apple-speech.mjs, scripts/build-desktop-artifact.ts, apps/desktop/scripts/*electron.mjs, apps/desktop/vite.config.ts	The Swift helper implements availability, locale preparation, and WAV transcription commands. Build and artifact staging compile and package it for macOS. Desktop build and launch scripts invoke the helper build.
Desktop service and IPC bridge packages/contracts/src/ipc.ts, apps/desktop/src/speech/AppleSpeech.ts, apps/desktop/src/ipc/*, apps/desktop/src/preload.ts, apps/desktop/src/main.ts, apps/desktop/src/speech/AppleSpeech.test.ts, apps/desktop/src/app/DesktopApp.test.ts	The desktop service locates and runs the helper, maps results, caches availability and successful locale preparation, and converts validated PCM to WAV. IPC contracts, handlers, and the preload bridge expose these operations. Tests cover service results, caching, and audio conversion.
On-device destination selection apps/web/src/speech/voiceConsent.ts, apps/web/src/speech/appleSpeech.ts, apps/web/src/components/settings/VoiceSettingsPanel.tsx, docs/internals/voice-input.md, docs/user/composer.md, docs/user/faq.md, docs/user/voice-input.md	Voice grants and settings support a device destination. The availability store probes the desktop bridge, and locale selection resolves automatic language from system and browser settings. The settings and documentation describe Apple Speech availability and its language and processing options.
On-device recording and transcription apps/web/src/speech/browserVoiceInput.ts, apps/web/src/speech/useEnvironmentSpeechInput.ts, apps/web/src/speech/useEnvironmentSpeechInput.browser.test.tsx	Device recordings use the Apple Speech platform without environment preparation. The platform prepares the locale, checks cancellation and audio consent, and sends PCM through the desktop bridge. Tests cover available and unavailable device dictation.

Suggested reviewers: juliusmarminge, t3dotgg

Merge Risk: Low · up to cfe62

Apple Speech dictation now shows its language control and disables the options it does not support. One limitation remains: after cancelling a recording while Apple Speech is preparing or transcribing, the next recording waits until that call finishes. This is usually a few seconds, but a first-time language download can take longer. It is a bounded delay rather than a failure.

Explanation

The title "feat(desktop): dictate on this Mac with Apple Speech" matches the main change. The PR adds an Apple Speech helper, a main-process service, and a macOS-only per-device transcription option in the desktop app. It is a conventional commit title in plain language and is concise.

Full details: Description check

Explanation

The description follows the repository template in structure. It has Problem, Change, Scope and approval, and Verification sections, plus a conventional-commit-style context. The Problem and Change sections are clear and specific. The Scope section links a discussion proposal and related issue #24938, but it does not state the bug being fixed, because the PR is a feature. The template says the repo accepts bug fixes, not features, so the scope section does not fully meet the template's requirement. The Verification section is thorough, with focused tests, manual checks, and before/after screenshots. The template's agent-model footer is present (Claude Opus 5.5 in Claude Code). The description is mostly complete, so the check passes, but the Scope section should explain why a feature PR is acceptable under the contribution rules.

Bound concurrent helper processes.

A renderer can invoke prepare with distinct locales or invoke transcribe repeatedly. Each call can spawn another helper, with no concurrency limit before the two- or ten-minute deadline. The IPC handler starts an Effect for each invocation, so repeated calls can exhaust desktop resources. Limit active helpers and reject excess requests rather than retaining an unbounded queue. (raw.githubusercontent.com)

Based on learnings, “In Electron IPC handlers, treat renderer arguments as untrusted.”

The in-app check and the screenshots are now in the PR description (Verification → In the desktop app on a Mac).

Summary: in vp run dev:desktop on an Apple Silicon Mac (macOS 27.0.1), the option is absent without the helper and shows with it. Dictation in the composer transcribed spoken audio in about 0.5 s (AppleSpeech.transcribe 306 ms), and macOS showed no speech recognition prompt. A first prepare for a new language (fr-FR) took 14.2 s for the asset download, then 0.07 s.

108-108: Trivial · Maintainability & Code Quality · Quick win

Define run with Effect.fn("AppleSpeech.run").

run is a parameterized helper that spawns the native helper process. It is an arrow that returns Effect.scoped(Effect.gen(...)). The repository rule for reusable Effect functions says to use Effect.fn("Service.operation") and not an arrow that returns Effect.gen. Similar internal desktop helpers, such as runCommandOutput in apps/desktop/src/shell/DesktopShellEnvironment.ts, already use this form.

Use Effect.fn("AppleSpeech.run")(function* (args, timeout) { ... }) with the helper's existing body. Pass Effect.scoped and the Effect.timeoutOrElse and Effect.catch handlers after the generator body as Effect.fn combinator arguments. The timeout combinator needs the timeout input, so it receives the function arguments. Keep the scope-based cleanup and the timeout and error mapping unchanged.

Label the device’s automatic choice as the Mac language.

cloudSpeechLanguages makes SpeechLanguageSelect display “Auto-detect.” Apple Speech instead sends the Mac’s preferred language to prepare. A user can therefore choose “Auto-detect” expecting multilingual detection and get a fixed language. Give the device destination its own automatic-choice label. (raw.githubusercontent.com)
