Inworld TTS

Generate speech audio from text using Inworld.ai's TTS API.

  1. Get API key from https://platform.inworld.ai
  2. Generate key with "Voices: Read" permission
  3. Copy the "Basic (Base64)" key
  4. Set environment variable:
export INWORLD_API_KEY="your-base64-key-here"

For persistence, add to ~/.bashrc or ~/.clawdbot/.env.

Installation

# Copy skill to your skills directory

API Reference

Endpoint Use
POST https://api.inworld.ai/tts/v1/voice Standard synthesis
POST https://api.inworld.ai/tts/v1/voice:stream Streaming for long text

Requirements

  • curl - HTTP requests
  • jq - JSON processing
  • base64 - Decode audio

Examples

# Quick test
export INWORLD_API_KEY="aXM2..."
./scripts/tts.sh "Testing one two three" test.mp3
mpv test.mp3  # or any audio player

# Different voice and speed
./scripts/tts.sh "Slow and steady" slow.mp3 --rate 0.8

# Fast-paced narration
./scripts/tts.sh "Breaking news!" fast.mp3 --rate 1.5

Troubleshooting

"INWORLD_API_KEY not set" - Export the environment variable before running.

Empty output file - Check API key is valid and has "Voices: Read" permission.

Streaming issues - Ensure jq supports --unbuffered flag.
