stt2desktop 0.1.2

Local speech-to-text for desktop using faster-whisper

stt2desktop

Local speech-to-text for desktop using faster-whisper.

Let's you dictate text into any application without sending audio to any cloud services. Everything runs locally on your machine — no internet connection required after the initial model was download.

Currently only tested under Linux with KDE ;)

How it works

1. Run ./cli.py listen (Whisper model downloaded on first run, cached on disk)
2. Hold Scroll Lock to record from your microphone
3. Release Scroll Lock — the audio is transcribed locally by faster-whisper
4. The text is typed into the focused window via wtype (Wayland) or xdotool (X11)

Install via pipx

Requirements: Python 3.12+, a working microphone, and either wtype (Wayland) or xdotool (X11):

sudo apt install wtype     # Wayland
sudo apt install xdotool   # X11

You can install "stt2desktop" with pipx:

sudo apt install pipx
pipx install stt2desktop

Then run:

stt2desktop listen

The default global hotkey is Scroll Lock (In german: "rollen"). You can change it via the --hotkey option (see below). Proposal for alternative key: ctrl_r, alt_r, cmd_r, shift_r ;)

CLI listen

usage: stt2desktop listen [-h] [LISTEN OPTIONS]

Start the STT listener. Hold the hotkey to record, release to transcribe and insert.

Whisper models

Just a selection and approximate values:

Model	Size	Speed	Accuracy
tiny	~75 MB	fastest	lowest
base	~145 MB	fast	good
small	~460 MB	slower	better (default)
medium	~1.5 GB	slow	high

Larger models produce more accurate transcriptions but take longer to process ;)

start development

At least uv is needed. Install e.g.: via pipx:

apt-get install pipx
pipx install uv

Clone the project and just start the CLI help commands. A virtual environment will be created/updated automatically.

~$ git clone https://github.com/jedie/stt2desktop.git
~$ cd stt2desktop
~/stt2desktop$ ./cli.py --help
~/stt2desktop$ ./dev-cli.py --help

usage: ./dev-cli.py [-h] {coverage,install,lint,mypy,nox,pip-audit,publish,test,update,update-readme-history,update-test-snapshot-files,version}
