whisper-1's verbose response carries a start and an end for every segment, and the file tab was reading only the start, to build the [mm:ss] prefix. Keeping the end as well is all an SRT needs. The text stays the authority on wording and the segments on timing; they meet at that prefix, which the cleanup model is already told to leave alone. So a transcript that went through cleanup still turns into properly timed subtitles. A line whose stamp matches no segment runs until the next line starts, a line with no stamp at all joins the cue above it, and an end that would run into the next cue is trimmed back. The button is dead until a timestamped run finishes, because without timestamps there are no segments to time anything with.

# Dikte
|
||
|
||
Press `Ctrl+Space`, talk, press again. The recording goes to OpenAI or OpenRouter
|
||
for transcription, a model on OpenRouter cleans it up (dropping the *uh*s, the
|
||
restarts, the missing punctuation), and the result lands in your clipboard and
|
||
is pasted into whatever window you were typing in.
|
||
|
||
Built for KDE Plasma 6 on Wayland. No dependencies beyond system packages:
|
||
just the Python standard library and PyQt6.

|
||
## Install
|
||
|
||
```sh
|
||
sudo pacman -S --needed pipewire-audio wl-clipboard ydotool ffmpeg python-pyqt6
|
||
systemctl --user enable --now ydotool # needed for auto-paste
|
||
|
||
./install.sh # or: ./install.sh "Ctrl+Alt+Space"
|
||
dikte # the settings window opens on first run
|
||
```
|
||
|
||
`install.sh` adds the `dikte` command, a menu entry, an autostart entry and the
|
||
KDE shortcut.
|
||
|
||
Two keys go in the settings window: **OpenAI** and **OpenRouter**. Speech to text
|
||
runs on either one (`gpt-4o-transcribe` by default), cleanup always on
|
||
OpenRouter (`google/gemini-3.5-flash-lite`), so a single OpenRouter key can
|
||
cover both. They fall back to `OPENAI_API_KEY` and `OPENROUTER_API_KEY`, and are
|
||
stored in `~/.config/dikte/config.json`, mode 600. Cleanup can be switched off,
|
||
in which case the raw transcript is pasted.
|
||
|
||
## Using it
|
||
|
||
| What | How |
|
||
| --- | --- |
|
||
| Start / stop recording | `Ctrl+Space`, or click the tray icon |
|
||
| Cancel a recording | Tray menu → *Cancel recording*, or `dikte cancel` |
|
||
| Settings | Tray menu → *Settings*, or `dikte settings` |
|
||
| Reload after an update | Tray menu → *Restart*, or `dikte restart` |
|
||
| Quit | Tray menu → *Quit*, or `dikte quit` |
|
||
|
||
An indicator in the screen corner shows a red dot, a live waveform and the
|
||
elapsed time, then the stage it is on. It never takes focus. Pressing
|
||
`Ctrl+Space` again while Dikte is still working does nothing; nothing queues up.
|
||
|
||
## What it does
|
||
|
||
- **Silence never reaches the API.** Handed near-silence, a transcription model
|
||
invents a sentence instead of returning nothing ("Thanks for watching", or in
|
||
Turkish "Altyazı M.K."). A recording is dropped when nothing rose 10 dB above
|
||
*that recording's own* noise floor for at least 0.3 s, which is also what
|
||
removes steady fan noise however loud, or when its loud end sits below
|
||
-55 dBFS. The indicator reports the level it measured, which is what you
|
||
calibrate the threshold against.
|
||
- **Misheard words are repaired.** Speech models fail phonetically on proper
|
||
nouns, so the cleanup model is asked to fix those from context, and to leave
|
||
the word alone when the context does not make the intended one clear. The names
|
||
you list under Cleanup rules go to the transcription model as a hint and to the
|
||
cleanup model as a glossary, which is what lets it recognise "kuber netis":
|
||
|
||
```
|
||
raw ıı bugün şey kuber netis üzerinde çalışan servisleri güncelledim
|
||
yani sonra grafanada bir panel açtım hani ve pay kut ile arayüzü
|
||
şey bitirdim işte
|
||
|
||
result Bugün Kubernetes üzerinde çalışan servisleri güncelledim. Sonra
|
||
Grafana'da bir panel açtım ve PyQt ile arayüzü bitirdim.
|
||
```
|
||
- **A failed cleanup is never silent.** The raw transcript is still pasted so the
|
||
dictation is not lost, but the indicator turns amber with the reason instead of
|
||
looking like a normal run.
|
||
- **Audio and video files** run through the same models under Settings → Audio
|
||
file, optionally with `[mm:ss]` timestamps, chunked through ffmpeg when long,
|
||
and saved as `.txt` or as `.srt` subtitles.
|
||
- **History** of every dictation under Settings → History, with a size limit and
|
||
right-click to delete.
|
||
- **Turkish and English interface**, following the system locale by default.
|
||
|
||
## The global shortcut needs one logout
|
||
|
||
KWin only reads `kglobalshortcutsrc` at startup, so the shortcut `install.sh`
|
||
writes will not fire until you log out and back in. Until then, Settings →
|
||
Shortcut → **built-in listener** reads `/dev/input` and catches the combination
|
||
itself. The difference: it does not swallow the key, so `Ctrl+Space` also reaches
|
||
the focused application (some editors will pop up autocomplete). The listener
|
||
needs your user in the `input` group: `sudo usermod -aG input $USER`.
|
||
|
||
## Layout
|
||
|
||
```
|
||
dikte.py entry point, tray icon, state machine, IPC
|
||
audio.py raw PCM capture through pw-record plus the level meter
|
||
api.py transcription on either provider, OpenRouter cleanup (stdlib only)
|
||
worker.py transcribe → clean up → clipboard → paste
|
||
vad.py deciding whether a recording holds speech at all
|
||
filetranscribe.py file transcription: ffmpeg, chunking, timestamps
|
||
overlay.py the corner indicator
|
||
settings_ui.py settings window
|
||
hotkey.py KDE shortcut installation and the evdev listener
|
||
paste.py wl-clipboard and ydotool wrappers
|
||
i18n.py the string table
|
||
```
|
||
|
||
The indicator is drawn through XWayland, because a Wayland client cannot place a
|
||
window in a screen corner; `dikte.py` sets `QT_QPA_PLATFORM=xcb` for that.
