Voice dictation for KDE Wayland: record, transcribe, clean up, paste

Browse Source

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
