Supernal Text-to-Speech API

High-quality, easy-to-use text-to-speech API that makes voice generation accessible to developers.

Why Supernal TTS?

Existing TTS solutions force developers to deal with:

Complex Integration: Multiple API calls, format conversions, and streaming protocols that require significant engineering effort
No Intelligent Caching: Regenerating the same audio repeatedly, wasting compute and increasing costs
Vendor Lock-in: Proprietary formats and workflows that make switching providers difficult

Supernal TTS API solves these core technical challenges:

Simplified Integration: Single API call gets you production-ready audio without complex workflows
Built-in Caching: Intelligent caching of generated audio reduces redundant compute and improves response times
Standard Formats: Clean, portable audio outputs that work anywhere
Predictable Performance: Consistent latency with cache hits providing near-instant responses

Whether you're building:

Accessibility features: Screen readers, content narration for visually impaired users
Voice interfaces: Interactive voice responses, virtual assistants
Content generation: Podcast narration, video voiceovers, audiobook creation
Educational tools: Language learning apps, reading assistance

The API is designed to be intuitive from your first API call. Visit tts-docs.supernal.ai for:
