});

Error Handling

The skill throws WindowsTtsError when the server returns an error:

typescript

try {
  await tts_notify({ text: "Test message" });
} catch (error) {
  if (error instanceof WindowsTtsError) {
    console.error(`TTS Server error: ${error.status}`);
  } else if (error.message.includes("timeout")) {
    console.error("TTS request timed out - check network connection");
  }
}

Best Practices

1. Network Reliability

• Ensure Windows PC has static IP or DHCP reservation
• Test connection with tts_get_status before critical reminders
• Set appropriate timeout (10-30 seconds for TTS)

2. Voice Selection

• Use zh-CN-XiaoxiaoNeural for warm, friendly Chinese announcements
• Use zh-CN-YunxiNeural for more formal notifications
• Match voice to message tone (casual vs formal)

3. Volume Management

• Set lower volume (0.5-0.7) for frequent reminders
• Use full volume (1.0) for urgent announcements
• Avoid very low volume (<0.3) as TTS may be inaudible

4. Message Design

• Keep messages concise (10-30 seconds max)
• Use clear, natural language
• Include context (time, action needed)
• Add polite markers for family harmony

Programmatic Usage

Use as a library in your TypeScript/JavaScript code:

typescript

import { WindowsTtsClient, validateConfig } from "./index";

const config = validateConfig({
  url: "http://192.168.1.60:5000",
  defaultVoice: "zh-CN-XiaoxiaoNeural",
  defaultVolume: 0.8
});

const client = new WindowsTtsClient(config);

// Send notification
await client.notify({
  text: "Hello from OpenClaw!"
});

// Check status
const status = await client.getStatus();
console.log(`Connected: ${status.connected}`);

Troubleshooting

"Connection refused" error

• Verify Windows TTS server is running: curl http://192.168.1.60:5000/status
• Check firewall allows port 5000
• Ensure both devices are on same network

"Request timeout" error

• Increase timeout in plugin config
• Check network latency between devices
• Verify Windows PC is not in sleep mode

TTS plays but wrong voice

• Verify voice name is valid Azure TTS voice ID
• Use tts_list_voices to see available voices
• Check Windows TTS server supports voice selection
