Installation

# Copy skill to your skills directory
cp -r inworld-tts /path/to/your/skills/

# Make script executable
chmod +x /path/to/your/skills/inworld-tts/scripts/tts.sh

# Optional: symlink for global access
ln -sf /path/to/your/skills/inworld-tts/scripts/tts.sh /usr/local/bin/inworld-tts

# With options
./scripts/tts.sh "Hello world" output.mp3 --voice Dennis --rate 1.2

# Streaming (for text >4000 chars)
./scripts/tts.sh "Very long text..." output.mp3 --stream

Options

`--voice`	Dennis	Voice ID
`--rate`	1.0	Speaking rate (0.5-2.0)
`--temp`	1.1	Temperature (0.1-2.0)
`--model`	inworld-tts-1.5-max	Model ID

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.
