Voice dictation for KDE Wayland: record, transcribe, clean up, paste
Ctrl+Space starts and stops a recording. The audio goes to OpenAI for transcription, a model on OpenRouter strips the fillers and restores punctuation, and the result is copied and pasted into the focused window. Only the Python standard library and PyQt6 — HTTP, multipart uploads and WAV writing are all hand-rolled. - pw-record captures raw 16 kHz mono PCM with a live level meter - the corner indicator is drawn through XWayland, since a Wayland client cannot position its own window - silence is caught before it costs an API call, relative to each recording's own noise floor, plus a filter for the stock phrases models invent when handed silence - audio and video files can be transcribed too, optionally with [mm:ss] timestamps, chunked through ffmpeg for long inputs - global shortcut installs as a KDE custom shortcut, with an evdev listener as a fallback until the session is restarted - Turkish and English interface, following the system locale by default
