Krotos Audio
The Industry-Standard Performative Sound Design Platform for AI-Enhanced Post-Production.
State-of-the-art 82M parameter text-to-speech model rivaling global leaders in latency and naturalness.
Kokoro is a revolutionary open-weight text-to-speech (TTS) model that achieves production-grade audio quality with a remarkably small footprint of just 82 million parameters. Based on the StyleTTS 2 architecture, Kokoro 2026 represents a shift in the AI landscape where high-fidelity, human-like synthesis no longer requires multi-billion parameter models or heavy cloud infrastructure. Its architecture leverages style vectors and adversarial training to maintain prosody and emotional nuance across multiple languages, including English and Japanese. By 2026, Kokoro has become the industry standard for local, edge-based TTS deployment due to its ability to perform sub-100ms inference on consumer-grade hardware and even mobile devices. The model supports various quantization formats, including ONNX and FP16, making it highly versatile for developers integrating voice into gaming, accessibility tools, and personal AI assistants. Unlike centralized black-box APIs, Kokoro offers complete transparency and data privacy, allowing enterprises to host the model entirely within their own secure perimeters without sacrificing the natural cadence found in premium paid services.
Uses a modified StyleTTS2 backbone with only 82 million parameters, allowing it to fit into minimal VRAM.
