Open Voice Input Linux v0.1.0-alpha.2

Open Voice Input Linux alpha.2 adds adaptive recognition corrections, link-aware DJI microphone selection, and optional local collection of audio/metadata pairs for future personal-ASR dataset work.

Highlights

• After an authoritative final is committed, a bounded five-second same-focus observation can learn one replacement for future dictations. The private adaptive ledger rejects conflicting, overlapping, cascading, cyclic, or unsafe rules; manual corrections remain authoritative.
• Microphone routing is re-evaluated before every dictation. An online DJI Mic Mini 2 is bound to that capture stream; a proven-offline receiver is excluded in favor of an unambiguous built-in/fallback input, including conservative recovery of a hidden input profile. Unknown link state preserves the normal system choice.
• Routing is application-scoped: the app does not request a playback-sink or desktop-wide default-source change, and it never hands an active utterance between microphones.
• Optional local data collection is disabled by default. When explicitly enabled and given a folder, an IBus-accepted authoritative final can publish one bounded WAV plus versioned JSON record using a background writer.
• Collected provider_final text is marked teacher-unreviewed; spoken_verbatim and preferred_output remain null until a future review workflow verifies them. This release does not upload to Orange, train a model, encrypt the dataset, provide review/delete UI, or create a fallback spool.
• Key, vocabulary, manual corrections, and adaptive memory are reloaded for each new dictation, so idle changes no longer require restarting the daemon.
• GTK settings, private configuration, installer, upgrade, uninstaller, service units, docs, bundle verification, and SBOM coverage were updated for these features.

Important alpha limitations

• Dictation temporarily switches to the murmur-voice IBus engine. During the adaptive observation lease, ordinary keys pass through, but the previous Rime/IBus engine may not be restored until the lease finishes or is ended early.
• Adaptive learning requires trustworthy IBus surrounding-text support. Unsupported, private, unfocused, ambiguous, insertion-only, or deletion-only cases learn nothing. This alpha has no settings switch for adaptive observation.
• DJI routing is evaluated only at dictation start. It does not switch microphones mid-utterance. Physical DJI online/offline behavior across the full device/application matrix remains an explicit alpha validation gap.
• The collector gives its background writer a bounded ten-second shutdown drain. A stalled mounted destination can leave only hidden unpublished staging; it never silently falls back to another local or cloud location.
• A fresh combined test of physical microphone, real provider account, representative applications, and a real mounted collection destination remains incomplete. Automated and VM verification used no microphone, provider key, or user recording.
• This preview targets Ubuntu 24.04 x86_64 with CPython 3.12. It is not a distribution-native or broadly qualified Wayland release.
• The companion Doubao Murmur right-Alt controller remains a separate controller-only project and release.
• Uninstall retains private key, vocabulary, correction, adaptive-memory, collection-setting, and external dataset files.

Audio is uploaded to Volcengine only during explicit dictation and is billed under the user's account. Local collection is independently opt-in; enabling it does not send the dataset anywhere.
