TalkFlow: Structured Latent Flow Matching for Speech Driven Holistic Motion Generation

TalkFlow introduces a structured latent flow framework for generating holistic co-speech motion, learning separate continuous latent representations for upper-body, lower-body, and facial expressions. The model incorporates lightweight cross-stream interactions to preserve part-specific dynamics and maintain coordination across motion components. Experiments on the BEAT2 dataset show improved facial expression accuracy, body gesture quality, and speech-motion synchronization compared to state-of-the-art methods.

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.

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.

Motion-Omni: End-to-End Joint Speech and Full-Body Motion for Spoken Dialogue

Motion-Omni is an end‑to‑end framework that jointly generates spoken dialogue and full‑body motion, producing speech, facial expressions, and hand, upper‑body, and lower‑body movements directly from the hidden states of a language model. The system requires joint training of the language model, speech generator, and motion generator to maintain audio‑motion alignment, and it is supervised using a scalable, model‑agnostic pipeline that pseudo‑labels 422,856 speech‑motion pairs. With a Qwen2.5‑7B‑Instruct backbone, Motion‑Omni‑Q7 achieves near‑cascade performance on motion metrics while being 5.4× faster, and it outperforms other non‑teacher cascades on beat correlation, diversity, and word error rate.

EMODY Flow: Emotion-Aware Audio-Driven Full-Body Motion Generation

EMODY Flow is a lightweight flow‑matching framework that generates synchronized full‑body motion and facial expressions conditioned on speech and emotion. It attaches to a frozen Qwen‑3 Omni model, reusing its audio codecs to drive two parallel DiT generators for SMPL‑X body pose and FLAME facial expressions. An auxiliary emotion classifier at training time restores emotion sensitivity, enabling EMODY Flow to achieve state‑of‑the‑art gesture quality on BEAT2 and zero‑shot facial animation on TFHP, with significant improvements in FGD, Beat Correlation, and Diversity metrics.

PAGE: Parts-Aware Guidance for Co-Speech Gesture Portrait Video Generation

PAGE (Parts-Aware Guidance) is a diffusion-based framework that improves co-speech gesture portrait video generation by enhancing local spatial fidelity and global audio‑visual consistency. It introduces Parts‑Specific Reweighting during training to focus supervision on key regions like lips, eyes, and hands, and Consistency Classifier Guidance plus Differential Guidance during inference to correct audio‑visual mismatches and refine motion separately. The authors also present the Chinese Announcer Speech (CAS) dataset, a large‑scale Chinese benchmark that expands on the PATS dataset, and demonstrate that PAGE outperforms existing methods in perceptual quality, gesture diversity, and audio‑visual alignment.

Super Star: Towards Streaming Real-time Interactive Agents for Digital Humans

The paper introduces a real‑time framework for generating co‑speech gestures for digital humans, coupling a streaming speech response module with a causal multimodal autoregressive gesture generator that uses only current speech and motion history. It also presents an offline data synthesis pipeline for virtual companion dialogues and a self‑evolving training loop that incorporates user feedback to continually adapt the model. Experiments show the system achieves a better latency‑quality trade‑off, stronger speech‑motion synchronization, and higher user preference than existing baselines.

FacePlex: Full-Duplex Joint Speech-Facial Motion Generation for Conversational Avatars

Natural face-to-face conversation requires real-time speech generation together with synchronized facial motion. Existing systems only partially address this problem: speech-only full-duplex models can generate speech in real time but do not produce facial motion, while audio-driven facial motion models animate a face from already available audio rather than jointly generating speech and motion online.
