Low-latency push-to-talk speech-to-text for Linux, built on faster-whisper with GPU acceleration and clean fallbacks. Works on Wayland and X11, with hotkey bindings provided by your window manager or keybinding tool.

This repo is a cleaned, production-ready version of a working F7/F9 push-to-talk workflow. It focuses on:

• Fast local transcription (GPU when available, CPU fallback when not)
• Configurable capture + output (type, clipboard, file, stdout)
• Wayland + X11 support
• Distro-agnostic setup with clear dependencies

git clone <your-repo-url>
cd SpeechToText
./scripts/install.sh

# Bind hotkeys (example: Hyprland)
# bind = , F7, exec, stt-ptt press en
# bindr = , F7, exec, stt-ptt release en

If you're using the whisper.cpp backend and want to skip Python setup:

STT_SKIP_PYTHON=1 ./scripts/install.sh

Push-to-talk commands:

stt-ptt press en
stt-ptt release en

Check status / cleanup:

stt-ptt status
stt-ptt cleanup

Copy the sample config:

cp config/config.env.example ~/.config/speech-to-text/config.env

Key settings:

• VOICE_MODEL — whisper model (e.g. large-v3-turbo)
• VOICE_DEVICE — cuda, cpu, or auto
• VOICE_SOURCE — Pulse/PipeWire source name
• VOICE_OUTPUT — type, clipboard, file, or stdout
• VOICE_ENGINE — faster-whisper (default) or whispercpp

Find audio sources:

pactl list sources short

Recording backends (any one works):

• pw-record (PipeWire)
• ffmpeg (Pulse/PipeWire)
• parec (PulseAudio / PipeWire-pulse)
• arecord (ALSA)

Output tools (choose one):

• Wayland: wtype or ydotool
• X11: xdotool
• Clipboard: wl-clipboard, xclip, or xsel

Python:

• Python 3.10+
• faster-whisper (installed via requirements.txt)

• Hyprland: examples/hyprland.conf
• Sway: examples/sway.conf
• GNOME: examples/gnome.md
• KDE: examples/kde.md
• keyd: examples/keyd.conf

If you want a Python-free backend, you can use whisper.cpp instead of faster-whisper.

1. Build or install whisper.cpp and get a .gguf model.
2. Set these in ~/.config/speech-to-text/config.env:

VOICE_ENGINE=whispercpp
VOICE_WHISPER_CPP_BIN=whisper-cli
VOICE_WHISPER_CPP_MODEL=/path/to/gguf/model.gguf
# Optional:
# VOICE_WHISPER_CPP_ARGS="-nt"

Notes:

• The script defaults to using -otxt/-of output if supported.
• If your build doesn't support those flags, set: VOICE_WHISPER_CPP_OUTPUT_MODE=stdout and add the right output flags in VOICE_WHISPER_CPP_ARGS.

Run diagnostics:

./scripts/diagnose.sh

Common issues:

• No audio captured → verify VOICE_SOURCE and pactl list sources short
• No typing → install wtype (Wayland) or xdotool (X11)
• CUDA errors → set VOICE_DEVICE=cpu or install correct CUDA libs

Audio is recorded to a temporary file in /tmp/speech-to-text and deleted after transcription. Set VOICE_KEEP_AUDIO=1 to keep the last recording for debugging.
