+# Local Whisper STT
+
+Local speech-to-text using OpenAI's Whisper. **Fully offline** after initial model download.
+
+## Usage
+
+```bash
+# Basic
+~/.clawdbot/skills/local-whisper/scripts/local-whisper audio.wav
+
+# Better model
+~/.clawdbot/skills/local-whisper/scripts/local-whisper audio.wav --model turbo
+
+# With timestamps
+~/.clawdbot/skills/local-whisper/scripts/local-whisper audio.wav --timestamps --json
+```
+
+## Models
+
+| Model | Size | Notes |
+|-------|------|-------|
+| `tiny` | 39M | Fastest |
+| `base` | 74M | **Default** |
+| `small` | 244M | Good balance |
+| `turbo` | 809M | Best speed/quality |
+| `large-v3` | 1.5GB | Maximum accuracy |
+
+## Options
+
+- `--model/-m` — Model size (default: base)
+- `--language/-l` — Language code (auto-detect if omitted)
+- `--timestamps/-t` — Include word timestamps
+- `--json/-j` — JSON output
+- `--quiet/-q` — Suppress progress
+
+## Setup
+
+Uses uv-managed venv at `.venv/`. To reinstall:
+```bash
+cd ~/.clawdbot/skills/local-whisper
+uv venv .venv --python 3.12
+uv pip install --python .venv/bin/python click openai-whisper torch --index-url https://download.pytorch.org/whl/cpu
+```
