About Dia AI by Nari Labs

Dia AI (DIA-1.6B) is an advanced text-to-speech (TTS) model developed by Nari Labs, designed to generate highly realistic speech from written transcripts. With Dia AI, you can assign different speakers to different lines, making it possible to create natural, multi-speaker conversations that sound authentic and engaging.

What Makes Dia AI Unique?

Beyond just converting text to speech, Dia AI stands out for its ability to produce non-verbal sounds such as laughter, coughing, and throat clearing, adding a new level of realism to generated audio. This makes it ideal for applications like dialogue generation, voiceover, and interactive storytelling.
