v0.3.15 — OmniVoice Studio

The cold-start release. Three "why is this broken on my machine" mysteries got solved at their roots: first generations stop dying at 300 seconds (the timeout was counting the model download as generation time — @moduvoice measured it on a Tesla T4: 0% GPU for the full window), updates stop deleting engines you installed yourself (the updater's dependency sync removed anything not in the app's lockfile — including things our own UI told you to install), and the "slower than v0.3.5" regression is found and fixed (clone profiles without a transcript were silently re-running a full Whisper transcription on every single generate). Also: Clear History is back, auto-played audio is finally stoppable, @stronghamjji hardened the dub pipeline against wedged transcribes, and @shakib30's community Colab notebook is now the linked no-GPU path. Thank you all.

Added

• Agent Skills: npx skills add debpalash/omnivoice-studio. Two installable skills now ship in the repo — omnivoice teaches any AI agent (Claude Code, Cursor, Codex, …) to speak and transcribe through your local install via the OpenAI-compatible API, including your cloned voices; oss-maintainer packages the maintainer methodology this project is run with.

Fixed

• A fresh install's first generation no longer dies at 300 seconds while the model is still downloading. The generate timeout was one clock around everything — including the engine's lazy multi-GB weight download on a cold start — so first requests burned the whole budget on the download (0% GPU the entire time, as a contributor's Tesla T4 verification measured) and failed with a misleading "too heavy for the available compute" error. Model loading now runs first under its own, much larger budget; the generate clock starts only once the engine is warm. A genuinely stalled download gets a new error that says so and points at Settings → Models. (#1033, #1037, evidence from #1014)
• The OpenAI-compatible speech endpoint stops silently discarding quality settings. POST /v1/audio/speech accepted num_step and guidance_scale in the request body with a 200 OK — and dropped them without a word, so API callers couldn't reach the model's documented quality preset (num_step: 32). Both are now declared, validated, and passed through to the engine, matching the native /generate endpoint. Caught by a contributor's measured Tesla T4 verification pass. (#1014)
• Updating no longer uninstalls engines you added yourself. Optional engines installed with pip into the app's environment (VoxCPM2, KittenTTS — exactly what Settings → Engines' own install hints say to do) were silently deleted by every app update, because the update's dependency sync removed anything not in the app's lockfile. Routine updates now leave your additions alone; the repair path ("Clean & Retry") still restores the exact known-good state, since a broken environment is sometimes caused by an extra package. (#1029)
• Voice cloning stops re-transcribing the same reference clip on every generate. Since v0.3.6, a profile saved without a transcript (the default) triggered a full ASR model load plus a transcription of the reference on every single synthesis — the "TTS got much slower than v0.3.5, same settings" regression. The first auto-transcription is now saved onto the profile, and repeated ad-hoc uploads of the same clip reuse a content-keyed transcript cache — so the cost is paid once, not per request. A transcript you typed yourself is never overwritten. (#1032)
• The Clear History button is back. The workspace redesign moved generation history into the right-side panels but dropped the old sidebar's clear-all control, leaving one-by-one deletion as the only way to empty a long history. Both the Voice and Dub history panels now have a Clear History button (with a confirmation), scoped to that workspace's history. (#1032)
• The audio that auto-plays after a render can finally be stopped anywhere. The finished-render playback has no on-screen player, and the only stop control lived in the Voice workspace's action bar — audio started from the Dub workspace, a profile preview, or after navigating away simply played to the end. A stop button now appears above the status area whenever such playback is active, on every page. The existing Settings → Appearance "Auto-play preview" toggle now also governs this playback, as its description always promised. (#1032)
