How to Use

In your API request, specify the voice style in the voice parameter when using text-to-speech: 
curl -X POST "https://app.navtalk.ai/generate" \
  -H "Content-Type: application/json" \
  -d '{
    "license": "your-api-key-here",
    "character_name": "navtalk.Leo",
    "content": "Welcome to NavTalk.",
    "voice": "echo"
  }'
