✨ What’s Changing

1️⃣ Voice Character Parameterization

We’re simplifying the voice system for clarity and flexibility.

Before: Over 1,100 granular voice IDs
Now: A streamlined, parameterized voice character structure
Emotional style options (e.g., happy, sad, angry) can now be passed as parameters
Each voice may support a different set of styles — use the Search Voices API to explore

📎 A full mapping document (old → new voice IDs) will be shared by end of April

2️⃣ Model Version Upgrade & Play/Voice Preset Integration

We are unifying voice models across all Supertone products.

New model upgrade (Coming Soon)
The new model upgrade extends API text input limit from 200 to 300 characters.
Clone voices created in Supertone Play can now be seamlessly used in the API.
