# Demo Speech Synthesis

CUTOS 4.0 LWA demo for `@cutos/speech-synthesis`. It uses the browser-side Web Speech API and Windows-installed voices. It does not require a CUTOS Provider, Device Driver, or Gateway service.

## Local Development

Build the sibling SDK first:

```sh
cd ../sdk
npm install
npm run build

cd ../demo-speech-synthesis
npm install
npm run dev
```

## LWA Build And Release

```sh
npx cutos lwa build
npx cutos login --username office
npx cutos lwa upload
npx cutos lwa list demo-speech-synthesis
npx cutos lwa publish --device <device-id>
```

The release version is managed only by `public/config.json`.

## Offline Validation

1. Run the LWA on a Windows CUTOS Runtime.
2. Confirm **Speech API Ready** and at least one listed voice.
3. Prefer a voice marked **Local** for offline operation.
4. Enter text and click **Speak**; the Activity card should show start and completion events.

If no voices are listed, install a Windows speech voice pack and restart the Runtime. Some WebView implementations require speech to start from a user interaction, so this demo always uses an explicit Speak button.
