Beyond APIs: Re-implementing a 44.1kHz TTS Engine from arXiv
Developers usually just wrap ElevenLabs. For ultra-low latency and studio quality, I went deeper. I re-implemented Supertonic v2 from scratch based on arXiv:2509.11084.
Technical Edge:
Zero Metallic sound: Replaced WaveNeXt with a HiFi-GAN generator for high-fidelity 44.1kHz audio.
Speed: Achieved x167 Real-Time Factor (RTF) on consumer GPUs.
Scale: ~260MB ONNX model optimized for high-load autonomous voice agents.
By engineering the pipeline at the neural level, I build AI that sounds human, not robotic. It's built for production, not just a demo.
Looking for custom, high-performance Voice AI infrastructure? Let’s talk architecture.
P.S. Video demo: 1st is Original, 2nd is AI-Generated. Hear the natural tone preservation.

There's a scene in Iron Man where Tony Stark walks back into his office, snaps his fingers, and everything just... works. The suits power up. JARVIS responds. The room recognizes him.
That scene lived in my head for 3 days while I built AIVA with Figma Make
AIVA is a voice-first agentic AI assistant — clap once to wake it, say what you need, and watch it handle your emails, meetings, calendar, customer tickets, and social media. All of it. Hands-free.
"Hey AIVA." That's all it takes.

A new interaction paradigm for AI.
Instead of regenerating outputs through prompt rewriting, users refine a single response through gesture. A horizontal drag movement allows the result to evolve across five preset axes based on user preferences.

This approach reduces prompt complexity, minimizes unnecessary iteration, and simplifies how we collaborate with AI systems.
The future of AI interaction may not be about better prompts, but better ways to shape outcomes.
