A few months ago, I wrote about discovering Wispr Flow and how it changed my workflow on Mac. The problem? I also work on Linux, and Wispr Flow isn’t available there.

I needed something that worked offline, respected my privacy, and just… worked.

This mattered more than you might think. I use Claude Code constantly, and I’d grown so accustomed to dictating my thoughts on Mac that working on Linux without it felt painful. Every time I sat down at my Linux machine, I’d instinctively reach for the dictation hotkey—and nothing would happen. Finding a solution that actually works has been a game-changer for my Linux workflow.

The Linux Gap

Voice dictation on Linux has always been a second-class citizen. Most solutions either send your audio to cloud services (privacy nightmare), don’t work properly with Wayland, or are just unreliable.

After some research, I found a solution that actually delivers: faster-whisper + ydotool.

How It Compares to Wispr Flow

Let me be honest about the differences.

Wispr Flow feels instantaneous—you speak, and the text appears almost immediately. My Linux setup types word by word, which initially seemed like a limitation.

But here’s the thing: I’ve actually grown to enjoy the slower pace.

Watching each word appear gives me time to double-check as it types. If something’s off, I notice immediately rather than finding mistakes after a wall of text has appeared. It’s a different rhythm, but not a worse one.

The transcription quality is excellent—surprisingly close to Wispr Flow for everyday speech. Technical terms and proper nouns sometimes need correction, but for general dictation it’s solid.

One thing that surprised me: the punctuation is handled beautifully. It knows when to put full stops, commas, and question marks without you having to say them explicitly. The text comes out feeling natural and readable, matching what I’d expect from Wispr Flow.

The Setup

The workflow is simple:

  1. Press Ctrl+Shift+Space to start recording
  2. Speak naturally
  3. Press Ctrl+Shift+Space again to stop
  4. Text gets transcribed and typed into the active window

Everything runs locally on CPU. No cloud services, no subscriptions, no internet required.

The Components

ydotool is the key piece for Wayland support. Unlike xdotool, it works at the kernel level so it doesn’t care whether you’re on X11 or Wayland. I built it from source from the GitHub repo.

faster-whisper handles the actual transcription—it’s a CTranslate2-based implementation of OpenAI’s Whisper model that runs efficiently on CPU.

I’m using the small model (466MB, needs about 2GB RAM). It’s a good balance between speed and accuracy. You can go smaller for faster results or larger for better accuracy:

Model Size RAM Notes
tiny 75 MB ~1 GB Fast but less accurate
base 142 MB ~1 GB Decent for quick notes
small 466 MB ~2 GB What I use - good balance
medium 1.5 GB ~5 GB Better accuracy, slower
large-v3 3 GB ~10 GB Best accuracy, needs patience

System Dependencies

sudo apt install portaudio19-dev python3-venv python3-pip git pulseaudio-utils libnotify-bin cmake libevdev-dev scdoc

The One Gotcha: Permissions

ydotool needs access to /dev/uinput to inject keystrokes. This requires:

  1. A udev rule at /etc/udev/rules.d/60-uinput.rules: 
    KERNEL=="uinput", MODE="0660", GROUP="input"

  2. Your user in the input group

  3. A logout/login for the group membership to take effect

Running as Services

Everything runs through systemd user services so it starts automatically on login:

# Check if it's running
systemctl --user status ydotoold
systemctl --user status dictation-listener

# View logs if something's wrong
journalctl --user -u dictation-listener -f

Was It Worth It?

Absolutely. Once it’s set up, it just works. I use it for:

  • Quick notes and drafts
  • Writing first passes of documentation
  • Responding to messages when my hands are tired
  • Brain dumps when I need to think out loud

The word-by-word typing that seemed like a limitation? It’s become a feature. I’m more present with what I’m dictating, catching errors in real-time rather than after the fact.

Different from Wispr Flow, but solving the same problem: removing the input bottleneck so I can work at the speed of thought.
