Sonic-AMG: Streaming Human Motion Generation from Spatial Audio

Sonic-AMG is a novel framework that generates human motion in real time from spatial audio, the first to do so in a streaming manner. It encodes acoustic content and body-relative source geometry as separate tokens, then uses a causal transformer with a flow head to produce continuous motion latents that a causal decoder turns into motion segments. The system introduces rehearsal training and spatial feedback to mitigate training‑inference mismatches, achieving state‑of‑the‑art FID and R‑precision on the SAM benchmark while enabling coherent, real‑time reactions to sound events and source locations.

InteractGesture: Progressive Chunk Guidance for Continuous Streaming Co-Speech Gesture Control

InteractGesture is a model‑agnostic, inference‑time method that enables fine‑grained spatial control of individual joints in continuous streaming co‑speech gesture generation. It guides diffusion sampler latent estimates through a differentiable RVQ‑VAE decoder, backpropagating spatial control gradients to adjust motion latents during sampling. To address chunk‑wise dependency issues in streaming generation, the method introduces Progressive Chunk Guidance, a chunk‑window strategy that keeps an active set of editable chunk latents with staggered delays, allowing spatial constraints to propagate gradients backward across chunk boundaries and reducing boundary inconsistencies.

AG-REPA: Causal Layer Selection for Representation Alignment in Audio Flow Matching

arXiv:2603. 01006v3 Announce Type: replace-cross Abstract: REPresentation Alignment (REPA) improves the training of generative flow models by aligning intermediate hidden states with pretrained teacher features, but its effectiveness in token-conditioned audio Flow Matching critically depends on the choice of supervised layers, which is typically made heuristically based on the depth.

GestureFAR: Streaming Co-Speech Gesture Generation with Flow Autoregression

GestureFAR is a flow‑autoregressive framework that generates natural co‑speech gestures from streaming speech while preserving causality and continuous motion expressiveness. It autoregresses over continuous motion latents using a transformer for audio‑motion context and a flow‑matching head to sample the next latent. A head‑only flow distillation strategy further reduces latency by collapsing multi‑step flow sampling into a single network evaluation, enabling real‑time token‑causal generation with improved quality‑latency trade‑off on the BEAT2 benchmark.
