Claims

C1strongest claim

We train SignaVox, a direct sign-to-sign conversational model that generates 3D body, hand, and facial motion responses from prior signing context without spoken-language text or externally provided glosses at inference time.

C2weakest assumption

That the recomposed continuous sign videos from isolated clips using BRAID accurately capture natural co-articulation and semantics, and that the retrieval-guided translator provides high-quality gloss sequences without significant errors.

C3one line summary

Constructs continuous sign conversation data from isolated signs using retrieval and diffusion models to train a direct sign-to-sign conversational AI.
