# FrameYap

Voice typing on Steam Frame, with recognition on the headset rather than a desktop or cloud server.
Hold a controller button to record, review the transcript, then deliberately type it into the focused app.
Standalone OpenVR overlay; no Steam store AppID or sudo. First release: v0.1.202609251524.

## Requirements

- Steam Frame with usable SteamVR/OpenVR and Gamescope for the **native** overlay and text delivery; Linux ARM64/glibc for the current installer payload format.
- For voice recognition, a **CPU Python runtime** (moondream 2.4.0 / Kestrel 0.8.0, CPU Torch 2.8.0) and the pinned local Parakeet Redux model. Neither is bundled; each has its own explicit install step: `sh install.sh --install-model --backend redux --yes` and `sh install.sh --install-runtime --yes` (needs Python 3.10–3.13 with venv; about 200 MB download). Use `--print-plan` first to see exactly what each fetches. There is no fallback ASR service.
- A local source build needs CMake 3.20+, C++20 and explicit native libraries/SDK; the default hardware-free build needs only CMake and C++20. See [build requirements](docs/build.md).

## Install

On the Frame, open a terminal (desktop mode's Konsole, or SSH) and run:

```sh
curl -fsSL https://github.com/baketnk/frame-yap/releases/latest/download/install.sh | sh
```

You can download and read `install.sh` first; it is one self-contained file. The installer pins its own release (currently `v0.1.202609251524`) and verifies the archive's SHA-256. It asks three y/n questions: install FrameYap, download the Parakeet Redux speech model (about 180 MB, CC-BY-4.0), and pip-install the CPU Python runtime (moondream/Kestrel with CPU Torch; about 200 MB download, roughly 1–1.5 GB on disk). Everything goes under your home directory: no sudo, compiler or Steam store AppID. Afterwards, launch **FrameYap** from the desktop application menu.

The release archive contains FrameYap, SDL3 and the OpenVR client library only; Kestrel, Torch, moondream and the model weights are fetched on your machine from PyPI and Hugging Face. For automation, the same steps are `sh install.sh --yes`, `sh install.sh --install-model --backend redux --yes` and `sh install.sh --install-runtime --yes`; add `--print-plan --json` to preview any step. Maintainers build release archives on Linux ARM64 with `sh scripts/build-release.sh WORKDIR VERSION`. See [packaging](docs/packaging.md) and [install design](docs/install-design.md).

## Controls (default Frame binding)

| Button / control | Action |
| --- | --- |
| Right X, hold / release | Record while held; release to transcribe. |
| Right B | Cancel/discard, or close the Quick phrases picker. |
| Right A | **Type:** queue reviewed text, normally with a trailing space. With nothing to review, a press queues Enter alone (so a quick double press types then submits). |
| Right Y | Open **Quick phrases**; press again to cycle the selection. |
| Left grip, double-tap | **Type + Enter:** queue the selected phrase verbatim + Enter, pending review (normally + space) then Enter, or Enter alone if neither exists. |
| Overlay Record / Stop | Click-to-start/stop alternative to the PTT binding. |
| Overlay Type / Type + Enter | The same deliberate text / Enter actions. |
| Overlay Hold Quit | Hold for 0.9 seconds, then release to quit (prevents accidental exit). |

Controls are remappable in SteamVR. Grip gestures may be unavailable with the dashboard open; pointer controls are an alternative. At the 4096-byte transcript limit, Type preserves the full text without appending a space if none fits. No speech commands, automatic Enter or automatic submit. Review is the default; Settings → Auto insert is opt-in, normally text + space only under continuously observed Xwayland focus. Type and Type + Enter now require a verified Xwayland target and use paced direct typing; Cancel stops remaining batches, never undoing prior input. The clipboard stays untouched. Check the destination before typing. Edit literal Quick phrases (`quick_inputs`) in `$XDG_CONFIG_HOME/frameyap/config.json`, then restart. See [overlay and settings](docs/overlay.md).

## Status / not yet validated

Native ARM64 build, CPU inference, overlay visibility, Gamescope API discovery and native-only installation have been exercised on Frame. The owner uses live microphone → reviewed transcript → paced delivery into real apps day to day, and the earlier front-prefix loss on repeated submissions (P1) is no longer observed. General app compatibility (for example browser fields), Auto insert with speech, physical resize, battery/thermal cost and a clean-account install are not yet validated. Local code/build status does not mean the device was updated. A completed Gamescope IME call means *input queued*, not that an app consumed or submitted it.

The native app normally keeps the mic device open while Ready and discards idle audio; it never mutes other applications' microphones. Settings → **Close mic when idle** (default OFF) closes it between clips, but reopening on PTT can cause an audio spike, delay or first-syllable clipping. **Lasers anytime** (default OFF) requests system-wide lasers while the panel is visible, potentially affecting games; it is not SteamVR's experimental input override. Review, settings, placement and diagnostic details: [overlay](docs/overlay.md), [worker](docs/worker.md), [design](docs/design.md).

Version output is numeric `frameyap MAJOR.MINOR.YYYYMMDDHHMM` (currently `0.1`); a development build may print `git HASH` and optionally `(uncommitted changes)` on a **separate** line. The UTC timestamp is set at configuration time (`SOURCE_DATE_EPOCH` can supply it); release archives must be built from a clean `v0.1.<timestamp>` tag. Offline model inventory and pinned SHA-256 checks in a source-tree build: `./build/frameyap --list-models`, `./build/frameyap --check-model redux --model-dir /absolute/model`, or `python3 scripts/model-status.py` with the same options. Packaging retains the verifier script for installed CLI use, which still needs a clean-account artifact check. Native `--run` accepts `--backend ID`, `--model-store /absolute/dir`, `--manifest-dir /absolute/dir` overrides; the installed launcher passes explicit flags through to the binary. These locally wired paths do not imply an installed release was tested or a model/runtime was supplied. No model or runtime is downloaded by status checks or on normal launch.

No recordings, transcripts, private logs, weights or CPU runtime binaries are committed. No default build/test downloads or initializes SteamVR, microphone or input injection.
