Local text-to-speech via sherpa-onnx (offline, no cloud).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# sherpa-onnx-tts
Local TTS using the sherpa-onnx offline CLI.
## Install
1. Download the runtime for your OS (extracts into `~/.bitterbot/tools/sherpa-onnx-tts/runtime`)
2. Download a voice model (extracts into `~/.bitterbot/tools/sherpa-onnx-tts/models`)
Update `~/.bitterbot/bitterbot.json`:
```json5
{
skills: {
entries: {
"sherpa-onnx-tts": {
env: {
SHERPA_ONNX_RUNTIME_DIR: "~/.bitterbot/tools/sherpa-onnx-tts/runtime",
SHERPA_ONNX_MODEL_DIR: "~/.bitterbot/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."`Read the whole file at its exact version.
How to install
mdr add bitterbot-ai/bitterbot-desktop/sherpa-onnx-tts@sha256:55f21fa4bc19dc88The line at the top of this page pins the label git:20260328.33f9833, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
