Problem

Place the caret after 코드를 in a Korean draft and dictate 검토. The editor inserts 코드를검토 instead of 코드를 검토. Its English-only boundary check also misses words ending in a combining mark, such as Hindi नमस्ते.

Change

When inserting at a caret, the shared dictation controller uses the recording’s language and recognizes Unicode letters, marks, and numbers next to the insertion. Korean and Hindi words get their space; Japanese and Thai stay joined. Auto-detect keeps its conservative behavior (Hello world, but Hello世界). Replacing a selection is unchanged.

Scope and approval

This is a focused draft-formatting bug: the transcript is correct, but inserting it joins two words. Only the insertion helper and its existing tests change; microphone capture, model selection, and where audio goes are unaffected. The fix comes from @nichtlegacy’s #13312 and was also included in @t3dotgg’s #25808.

Verification

Ran vp test run packages/client-runtime/src/voice-input/controller.test.ts on 2c859cc: 43/43 passed. The cases cover both sides of the caret, Hindi combining marks, characters outside the BMP, Japanese and Thai spacing, auto-detect, and selection replacement. Tested the resulting draft text directly; this head wasn’t exercised with a physical iPhone microphone.

Approvability

Verdict: Approved at 2c859cc

Macroscope's review found this PR approvable — Dictation now inserts Unicode-aware word spacing for additional languages while preserving spaceless-language and auto-detect handling. The change is confined to draft formatting and retains existing stale-draft safeguards.

Walkthrough

resolveTranscriptCommit now applies automatic spacing based on the locale and nearby text. Tests add supplementary-plane digit coverage and insertion-at-caret cases for six locales.

Changes: Transcript spacing

Layer / File(s)Summary
Locale-based transcript spacing
packages/client-runtime/src/voice-input/controller.ts, packages/client-runtime/src/voice-input/controller.test.ts		The controller normalizes the locale’s primary language subtag and checks up to two characters on each side of the caret. It uses Unicode letter, mark, and number boundaries for known languages, retains Latin letter and number checks for auto, and skips spacing for listed languages. Tests cover supplementary-plane digits and locale-specific insertion cases.

Merge Risk: External image Low · up to 2c859

A concurrent model change can add an unwanted space to a transcript. The text remains editable, so this is a limited merge risk.
