feat(speech): recommend local models for selected languages - #33336
Settings relies on five fixed Recommended flags regardless of the languages selected in the model browser. First-run setup uses the same flags when the selected model cannot transcribe the requested language, overlooking better measured candidates.
Change
Use one shared benchmark policy for Settings and first-run setup. Candidates must support and have accuracy measurements for every selected language. Catalog generation applies license and loader exclusions before candidates are scored.
Offer up to three distinct suggestions: Recommended balances accuracy and speed; Faster must be quicker than Recommended; More accurate must improve accuracy within the longer processing budget. Each model gets one badge, with Recommended, Faster, then More accurate precedence. Missing measurements stay unscored, and All languages remains neutral.
Score every role using the destination environment's existing CPU/GPU reference tier, including its reported Auto CPU fallback. This deliberately adapts Handy's mixed-tier policy so recommendations and displayed speeds describe the same backend. These remain reference comparisons, not predictions of the person's hardware.
Keep recommendations in the existing Recommended order, preserving active, installed, and downloading groups. Manual size, first-selected-language accuracy, and speed sorts retain their order. Badges use the language selection before text search and Downloaded only filtering, so a search does not invent a new global winner.
Preserve setup's suitable selected-model priority, language preference order, actual-language/Auto safeguards, no-preference behavior, errors, and download flow. Setup fetches benchmarks once; progress polls retain the computed label without repeatedly fetching measurements.
Keep full timing precision for ranking and generate the small policy JSON from the pinned Handy package. Clients do not import the upstream catalog or benchmark machinery. Retain the five legacy Recommended flags for older clients; the updated Settings and setup paths calculate their own language-aware recommendations.
Scope and approval
The direction and scope were explicitly requested in the development session: language-aware recommendations in the existing desktop/web model browser and first-run setup, including remote transcription environments. This intentionally changes recommendation defaults. No public approval discussion was supplied.
The current diff contains the shared recommendation policy, catalog precision/policy generation, and Settings/setup integration. The speech contract, compatible wire codec, and server tier reporting already exist on main and are unchanged here. Mobile only rounds its existing accelerated-speed display to accommodate the full-precision catalog. There is no new language profile, onboarding step, sort mode, model browser, auxiliary detector, recording-language behavior, or actual hardware benchmarking.
Verification
On current head 57c07de, all 129 focused tests passed across the speech contract, shared recommendation/setup helper, catalog generation, SpeechService, model browser, Settings/relay integration, and first-run browser integration. Coverage includes multiple languages, excluded candidates, incomplete measurements, strict alternative roles, CPU/GPU selection, Auto fallback, legacy responses, manual sorts/filters, and setup safeguards.
Current-head GitHub CI is green, including lint, build/typecheck, server and web tests, and release smoke validation.
Compared the generated catalog with main: all 59 models retain the same legacy recommendation flags, including the five Recommended models. Timing differences are only the intended additional precision; rounding them to two decimals reproduces main's values.
The earlier integrated real-client pass used isolated seeded state: language changes, English and German together, neutral All languages browsing, all manual sorts, accuracy-sort persistence, contextual badges, search, and Downloaded only combined with search. A second isolated server was paired and selected for transcription. Its GPU references differed from the primary CPU setting, changing its hardware switched recommendations and timings together, and first-run setup retained its suitable selected English model. This manual pass predates the latest main merge.
Known minor compatibility limitation: older clients can decode the response but display full-precision timing numbers directly. Updated web and mobile clients round their display to two decimals.
No real model download or microphone recording was performed. Download and failure paths are covered by integration tests. The Electron shell was not launched separately.
Before, fixed recommendations for English and German:
After, recommendations for the same languages on the selected environment's GPU tier:
CPU/GPU comparison and remote setup captures. Japanese on CPU recommends SenseVoice and offers Fun-ASR Nano Multilingual as More accurate; GPU recommends Fun-ASR and offers SenseVoice as Faster. Final Settings captures disable the existing scroll-fade mask in the test page only to work around missing content in Browser panel captures. Evidence is hosted on GitHub outside the code repository.
Implemented with gpt-6.1-sol using the Codex harness in T3 Code.
Macroscope's review found this PR requires human approval — Language-specific benchmark recommendations now affect model badges, ordering, and the fallback model offered during first-run setup. The changed default offer requires a human to accept its accuracy, speed, and download-size tradeoffs.

Speech recommendations now use benchmark measurements for the active CPU or accelerated tier and selected languages. Catalog generation publishes recommendation policy and precise timings. Setup selection and settings displays use the resulting recommendations.

Summary
Catalog benchmarks and policy generation apps/server/scripts/sync-speech-catalog.ts, apps/server/scripts/speech-catalog.ts, apps/server/scripts/speech-catalog.test.ts, apps/server/src/speech/catalog.json
Catalog generation calculates CPU and accelerated timings without rounding. The sync script generates and checks the recommendation policy as well as the catalog. Tests cover benchmark calculations, policy matching, and recommendation results.
Shared recommendation and setup selection packages/shared/src/speech.ts, packages/shared/src/speechRecommendationPolicy.json, packages/shared/src/speech.test.ts
recommendSpeechModels assigns recommendation roles using language coverage, benchmark measurements, and policy settings. chooseSetupSpeechModel takes a benchmark tier and returns whether its selected model is recommended.
Tier-aware setup model selection apps/web/src/speech/useEnvironmentSpeechInput.ts, apps/web/src/speech/useEnvironmentSpeechInput.browser.test.tsx
Setup catalog loading passes the environment’s benchmark tier to model selection. Refreshes preserve the recommendation flag. Tests cover tier-specific model selection and catalog loading.
The settings browser sorts by recommendation role and active benchmark tier. Model cards distinguish recommended, faster, and more accurate roles. Benchmark displays handle missing tiers and measurements and show rounded timing values. Tests and user guidance reflect these changes.

verified current head 57c07debc29668900f930f5b64811e55ad02cdb1 as-is on this linux boat vm. reproduced the fixed badges on github/main (fa2f4ff2a2) in a separate worktree, stopped that server, installed the exact pr head and started its real dev server. drove the web client with repository playwright and /usr/bin/google-chrome. created a new git project and thread through the app. no mocked services or scenario fixtures.
japanese changes from three fixed recommended badges to sensevoice small (recommended) and fun-asr nano multilingual (more accurate). english + german changes from four fixed badges to parakeet ultra (recommended) and orukeet (faster).
all languages has no contextual badges. text search combines with language selection and downloaded-only filtering. smallest-download, fastest-transcription and first-language accuracy sorts work. the installed selected model keeps priority when it matches the language filter.
a japanese browser reaches first-run setup from the composer, receives sensevoice small with the japanese recommendation, downloads the real 241 mb model and silero, and reaches the enabled start dictating step.
a real codex gpt-6.1-sol turn completed through the web client with the response: speech verification ready.
explicit cpu selection works. auto without gpu devices uses cpu reference timings and recommendations.

physical microphone recording and speech transcription were not exercised on this vm. gpu acceleration and auto fallback after a real gpu failure were unavailable because the vm reports no gpu devices. separate remote/relay environments, mixed-version clients, native electron, ios/android, macos and windows were not exercised. automated browser and policy coverage passed; it does not replace those hardware and native-client checks.

The byte-equality check can pass if both the generator and catalog mark these models as not recommended. Older clients use the flags for setup selection and sorting. Add an assertion for the five legacy model IDs to the existing test.
