Add Voice Replies (ElevenLabs)

When someone sends a voice note, the bot replies with a voice note instead of text. Uses ElevenLabs TTS.

Setup

1. ElevenLabs API key

Ask the user to:

1. Sign up at elevenlabs.io
2. Go to Settings > API Keys
3. Copy the API key

Add to .env:

ELEVENLABS_API_KEY=<key>

2. Pick a voice

Ask: "Which voice should the bot use? You can browse voices at elevenlabs.io/voice-library, or use a custom/cloned voice."

If they have a specific voice, get the voice ID from the ElevenLabs dashboard. If not, suggest they browse the library and pick one that fits.

Add to .env:

ELEVENLABS_VOICE_ID=<voice_id>

If they skip this, the default voice will be used.

3. Rebuild and restart

npm run build
launchctl kickstart -k gui/$(id -u)/com.ghostclaw  # macOS
# systemctl --user restart ghostclaw                # Linux

4. Test

Tell the user to send a voice note to the bot. It should reply with a voice note using the selected voice. Text messages still get text replies.

How it works

The bot detects when an incoming message is a voice note (tagged [Voice: ...] after transcription). When replying to a voice message, it converts the text response to audio via ElevenLabs TTS and sends it as a voice note. Text messages always get text replies.

Disabling

Remove ELEVENLABS_API_KEY from .env and restart. The bot will fall back to text replies for everything.
