What is dia-tts.com?
Dia TTS is a cutting-edge AI text-to-speech model designed for ultra-realistic dialogue synthesis. Developed by Nari Labs and released under the Apache 2.0 license, this 1.6B parameter model generates natural and expressive speech output that rivals commercial solutions. The model produces incredibly natural-sounding voices with human-like intonation, rhythm, and emotion, creating speech that's nearly indistinguishable from human voices.
The platform supports multi-speaker conversations using simple tags like [S1] and [S2] to specify different voices in text, maintaining consistent and natural dialogue. It also features voice cloning capabilities through audio prompting, enabling consistent voice identity across multiple generations for personalized speech output. The model runs on 10GB VRAM and can generate audio in real-time on enterprise-grade GPUs, with quantized versions planned for improved accessibility on lower-end hardware.
