sherpa-onnx-tts
Sherpa-onnx-tts enables offline text-to-speech synthesis using the sherpa-onnx CLI tool and local voice models. Use this skill when you need to generate speech audio files entirely on your machine without relying on cloud services, requiring initial setup of the sherpa-onnx runtime and a voice model like vits-piper.

# sherpa-onnx-tts
Local TTS using the sherpa-onnx offline CLI.
## Install
1. Download the runtime for your OS (extracts into `$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/runtime`, default `~/.moltis/tools/sherpa-onnx-tts/runtime`)
2. Download a voice model (extracts into `$OPENCLAW_STATE_DIR/tools/sherpa-onnx-tts/models`, default `~/.moltis/tools/sherpa-onnx-tts/models`)
Resolve the active state directory first:
```bash
STATE_DIR="${OPENCLAW_STATE_DIR:-$HOME/.Moltis}"
```
Then write those resolved paths into the active Moltis config file (`$OPENCLAW_CONFIG_PATH`, default `~/.moltis/Moltis.json`):
```json5
{
skills: {
entries: {
"sherpa-onnx-tts": {
env: {
SHERPA_ONNX_RUNTIME_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/runtime",
SHERPA_ONNX_MODEL_DIR: "/path/to/your/state-dir/tools/sherpa-onnx-tts/models/vits-piper-en_US-lessac-high",
},
},
},
},
}
```
The wrapper lives in this skill folder. Run it directly, or add the wrapper to PATH:
```bash
export PATH="{baseDir}/bin:$PATH"
```
## Usage
```bash
{baseDir}/bin/sherpa-onnx-tts -o ./tts.wav "Hello from local TTS."
```
Notes:
- Pick a different model from the sherpa-onnx `tts-models` release if you want another voice.
- If the model dir has multiple `.onnx` files, set `SHERPA_ONNX_MODEL_FILE` or pass `--model-file`.
- You can also pass `--tokens-file` or `--data-dir` to override the defaults.
- Windows: run `node {baseDir}\\bin\\sherpa-onnx-tts -o tts.wav "Hello from local TTS."`Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Manage Apple Notes via the memo CLI on macOS (create, view, search, edit).
Manage Apple Reminders via remindctl CLI (list, add, complete, delete).
Generate dark-themed SVG diagrams of software systems and cloud infrastructure as standalone HTML files with inline SVG graphics. Semantic component colors (cyan=frontend, emerald=backend, violet=database, amber=cloud/AWS, rose=security, orange=message bus), JetBrains Mono font, grid background. Best suited for software architecture, cloud/VPC topology, microservice maps, service-mesh diagrams, database + API layer diagrams, security groups, message buses — anything that fits a tech-infra deck with a dark aesthetic. If a more specialized diagramming skill exists for the subject (scientific, educational, hand-drawn, animated, etc.), prefer that — otherwise this skill can also serve as a general-purpose SVG diagram fallback. Based on Cocoon AI's architecture-diagram-generator (MIT).
Search and retrieve academic papers from arXiv using their free REST API. No API key needed. Search by keyword, author, category, or ID. Combine with web_extract or the ocr-and-documents skill to read full paper content.
Generate ASCII art using pyfiglet (571 fonts), cowsay, boxes, toilet, image-to-ascii, remote APIs (asciified, ascii.co.uk), and LLM fallback. No API keys required.
Production pipeline for ASCII art video — any format. Converts video/audio/images/generative input into colored ASCII character video output (MP4, GIF, image sequence). Covers: video-to-ASCII conversion, audio-reactive music visualizers, generative ASCII art animations, hybrid video+audio reactive, text/lyrics overlays, real-time terminal rendering. Use when users request: ASCII video, text art video, terminal-style video, character art animation, retro text visualization, audio visualizer in ASCII, converting video to ASCII art, matrix-style effects, or any animated ASCII output.
PyTorch library for audio generation including text-to-music (MusicGen) and text-to-sound (AudioGen). Use when you need to generate music from text descriptions, create sound effects, or perform melody-conditioned music generation.
