Nari Labs has unveiled Dia-1.6B, a compact yet powerful open-source text-to-speech model that challenges industry leaders like ElevenLabs and Sesame. Despite its modest size—just 1.6 billion parameters—the model delivers strikingly expressive speech, capable of weaving laughter, coughs, and even screams of terror into its output. Yet the breakthrough comes with a caveat: while the voices border on human-like, they still stumble over the subtleties of emotion, leaving them stranded in the uncanny valley. The achievement underscores how far AI has come—and how far it still has to go.
