Deepdub TTS

What this skill does

This skill converts text into speech using Deepdub and returns an audio file as a MEDIA: attachment that OpenClaw can send to channels like Telegram.

Requirements

• Python 3.9+
• Deepdub API access

Permissions

This skill requires permission to:

• Execute deepdub_tts.py (the bundled script)
• Write audio files to OPENCLAW_MEDIA_DIR only (output path cannot be overridden via CLI arguments)

Setup

Set the following environment variables where OpenClaw runs:

Required:

• DEEPDUB_API_KEY – your Deepdub API key
• DEEPDUB_VOICE_PROMPT_ID – default voice prompt to use

Optional:

• DEEPDUB_LOCALE (default: en-US)
• DEEPDUB_MODEL
• OPENCLAW_MEDIA_DIR (default: /tmp/openclaw_media)
