The native app previously hid dictation when it couldn’t transcribe on-device. Android and iOS now keep This device as the default and let the user explicitly choose a paired environment under Settings → Voice. The confirmation identifies the host; microphone permission alone does not authorize an upload.

The grant stays on that phone. Only a finished recording can go to the chosen environment, over its authenticated connection. Revoking or replacing the grant cancels pending work, even if the user later reselects the same host. A disconnected or incompatible host disables environment dictation; nothing silently switches destinations. This uses the existing transcription transport and does not add a cloud service.

Picking an environment used to skip checking that it had a transcription model, so the first recording failed and the phone had no way to fix it. Each environment row now says when no model is installed. The chosen environment gets a model row that opens a searchable sheet of its full catalog, with accuracy, speed, language count, and size. From there the user can download a model (with progress and cancel) or switch the active one. Phones without permission to change that environment's settings see the list read-only.

Model row in Settings → Voice	Model sheet
Voice settings with the chosen environment and its active model row	Model sheet showing scores, language count, size, and an installed model

Stacked on #30624. Verified check:changed and a Pixel 9 without local recognition: selected the host, recorded in the composer, and saw the chosen server return HTTP 200 for the upload. The emulator was silent, and the composer reported no speech without changing the draft. Started a second recording and switched back to This device while it was running: the recording stopped, and the server received no second upload. The iOS simulator build succeeded, but the device runner could not keep the app open for an interactive pass; verify that path before landing.

Before: no local recognizer	After: local default, paired host available	Before audio can leave
Before: dictation unavailable	After: This device is selected; paired environment is unchecked	Confirmation identifies where microphone audio will go

Walkthrough

Mobile voice input supports on-device transcription by default or transcription through a selected paired environment. The changes add Android and iOS recording decoders, secure destination grants, environment transcription routing, and microphone settings for selecting a destination.

Changes: Mobile voice transcription

Layer / File(s)	Summary
Native recording decoder `apps/mobile/modules/t3-voice-transcription/...`, `apps/mobile/.swiftlint.yml`	The Expo module now registers Android and Apple platforms. Both native modules decode local recordings to mono 16 kHz signed 16-bit PCM and enforce recording-length limits.
Environment transcription routing `apps/mobile/src/features/voice-input/voiceGrantStorage.ts`, `apps/mobile/src/features/voice-input/voiceDestination.ts`, `apps/mobile/src/features/voice-input/environmentTranscriber.ts`, `apps/mobile/src/features/voice-input/*test.ts`	Secure storage persists voice grants. Environment routing checks connection and grant state, decodes and validates PCM, then sends transcription requests. Tests cover grant changes, storage failures, routing, and recording limits.
Voice input and destination settings `apps/mobile/src/features/voice-input/VoiceInputProvider.tsx`, `apps/mobile/src/features/settings/SettingsMicrophoneRouteScreen.tsx`, `apps/mobile/src/features/settings/settings-search.ts`, `docs/internals/voice-input.md`, `docs/user/composer.md`, `docs/user/faq.md`, `docs/user/voice-input.md`	Voice input uses route-aware availability and transcription, and cancels active sessions when the route changes. Microphone settings offer device and environment choices. Documentation describes destination selection and mobile transcription behavior.

Full details: Title check

Explanation

The title "feat(mobile): opt in to dictation on a paired environment" matches the main change. The changeset adds an opt-in route that lets mobile users send finished dictation recordings to a paired environment, while on-device transcription stays the default. The title is specific, uses conventional commit form, and is 57 characters long.

Full details: Description check

Explanation

The description is mostly complete and includes verification results and UI evidence. Add the required section headings and a link to explicit maintainer approval; the stacked PR link alone does not establish approval. Clarify the settings path and whether the model picker is part of this PR, because the supplied change summary does not describe it.

Fix the stale privacy statement in the mobile voice input section.
Line 219 says "Transcription runs on your device." This is now wrong. The same section (Lines 192-198) describes choosing a paired environment, and in that case finished recordings go to that environment. A user who opted in would read a false claim about where audio goes. This sentence is the privacy statement for the feature.
The lines are outside the changed hunk. This PR makes them inaccurate.

Replace the per-sample DataView calls with an Int16Array view.
A five-minute recording has about 4.8 million samples. The loop makes one getInt16 call per sample on the JS thread. This can stall the UI for a noticeable time when the user finishes a long recording. The repository guidelines ask for changes that consider performance.
All supported React Native targets are little-endian. A copied Int16Array also avoids alignment problems when decoded.byteOffset is odd.

Also addressed the two items in the review summary in 7f973ec: the composer guide now distinguishes deleting the phone’s temporary recording from sending audio to a chosen environment. PCM conversion uses an aligned Int16Array view for the ordinary case, with an alignment-safe fallback covered by a test. Both focused suites (6 tests) and check:changed pass. I couldn’t repeat the Android device run on this head: the native client wasn’t cached and Gradle reported “SDK location not found” on the build host.
