Incorporating Spatial Awareness in Data-Driven Gesture Generation for Virtual Agents

no code implementations7 Aug 2024 Anna Deichler, Simon Alexanderson, Jonas Beskow

This paper focuses on enhancing human-agent communication by integrating spatial context into virtual agents' non-verbal behaviors, specifically gestures.

Fake it to make it: Using synthetic data to remedy the data shortage in joint multimodal speech-and-gesture synthesis

no code implementations30 Apr 2024 Shivam Mehta, Anna Deichler, Jim O'Regan, Birger Moëll, Jonas Beskow, Gustav Eje Henter, Simon Alexanderson

Specifically, we use unimodal synthesis models trained on large datasets to create multimodal (but synthetic) parallel training data, and then pre-train a joint synthesis model on that material.

Unified speech and gesture synthesis using flow matching

no code implementations8 Oct 2023 Shivam Mehta, Ruibo Tu, Simon Alexanderson, Jonas Beskow, Éva Székely, Gustav Eje Henter

As text-to-speech technologies achieve remarkable naturalness in read-aloud tasks, there is growing interest in multimodal synthesis of verbal and non-verbal communicative behaviour, such as spontaneous speech and associated body gestures.

Diffusion-Based Co-Speech Gesture Generation Using Joint Text and Audio Representation

no code implementations11 Sep 2023 Anna Deichler, Shivam Mehta, Simon Alexanderson, Jonas Beskow

The output of the CSMP module is used as a conditioning signal in the diffusion-based gesture synthesis model in order to achieve semantically-aware co-speech gesture generation.

Diff-TTSG: Denoising probabilistic integrated speech and gesture synthesis

no code implementations15 Jun 2023 Shivam Mehta, Siyang Wang, Simon Alexanderson, Jonas Beskow, Éva Székely, Gustav Eje Henter

With read-aloud speech synthesis achieving high naturalness scores, there is a growing research interest in synthesising spontaneous speech.

Denoising Speech Synthesis

Listen, Denoise, Action! Audio-Driven Motion Synthesis with Diffusion Models

1 code implementation17 Nov 2022 Simon Alexanderson, Rajmund Nagy, Jonas Beskow, Gustav Eje Henter

Diffusion models have experienced a surge of interest as highly expressive yet efficiently trainable probabilistic models.

Integrated Speech and Gesture Synthesis

1 code implementation25 Aug 2021 Siyang Wang, Simon Alexanderson, Joakim Gustafson, Jonas Beskow, Gustav Eje Henter, Éva Székely

Text-to-speech and co-speech gesture synthesis have until now been treated as separate areas by two different research communities, and applications merely stack the two technologies using a simple system-level pipeline.

Transflower: probabilistic autoregressive dance generation with multimodal attention

no code implementations25 Jun 2021 Guillermo Valle-Pérez, Gustav Eje Henter, Jonas Beskow, André Holzapfel, Pierre-Yves Oudeyer, Simon Alexanderson

First, we present a novel probabilistic autoregressive architecture that models the distribution over future poses with a normalizing flow conditioned on previous poses as well as music context, using a multimodal transformer encoder.

Generating coherent spontaneous speech and gesture from text

no code implementations14 Jan 2021 Simon Alexanderson, Éva Székely, Gustav Eje Henter, Taras Kucherenko, Jonas Beskow

In contrast to previous approaches for joint speech-and-gesture generation, we generate full-body gestures from speech synthesis trained on recordings of spontaneous speech from the same person as the motion-capture data.

Robust model training and generalisation with Studentising flows

1 code implementation11 Jun 2020 Simon Alexanderson, Gustav Eje Henter

Normalising flows are tractable probabilistic models that leverage the power of deep learning to describe a wide parametric family of distributions, all while remaining trainable using maximum likelihood.

MoGlow: Probabilistic and controllable motion synthesis using normalising flows

3 code implementations16 May 2019 Gustav Eje Henter, Simon Alexanderson, Jonas Beskow

Data-driven modelling and synthesis of motion is an active research area with applications that include animation, games, and social robotics.
