ADEPT: A Dataset for Evaluating Prosody Transfer

no code implementations15 Jun 2021 Alexandra Torresquintero, Tian Huey Teh, Christopher G. R. Wallis, Marlene Staib, Devang S Ram Mohan, Vivian Hu, Lorenzo Foglianti, Jiameng Gao, Simon King

Text-to-speech is now able to achieve near-human naturalness and research focus has shifted to increasing expressivity.

Ctrl-P: Temporal Control of Prosodic Variation for Speech Synthesis

no code implementations15 Jun 2021 Devang S Ram Mohan, Vivian Hu, Tian Huey Teh, Alexandra Torresquintero, Christopher G. R. Wallis, Marlene Staib, Lorenzo Foglianti, Jiameng Gao, Simon King

Text does not fully specify the spoken form, so text-to-speech models must be able to learn from speech data that vary in ways not explained by the corresponding text.

Scattering Networks on the Sphere for Scalable and Rotationally Equivariant Spherical CNNs

no code implementations ICLR 2022 Jason D. McEwen, Christopher G. R. Wallis, Augustine N. Mavor-Parker

Convolutional neural networks (CNNs) constructed natively on the sphere have been developed recently and shown to be highly effective for the analysis of spherical data.

Efficient Generalized Spherical CNNs

1 code implementation ICLR 2021 Oliver J. Cobb, Christopher G. R. Wallis, Augustine N. Mavor-Parker, Augustin Marignier, Matthew A. Price, Mayeul d'Avezac, Jason D. McEwen

We develop two new strictly equivariant layers with reduced complexity $\mathcal{O}(CL^4)$ and $\mathcal{O}(CL^3 \log L)$, making larger, more expressive models computationally feasible.

Wavelet-Based Segmentation on the Sphere

no code implementations21 Sep 2016 Xiaohao Cai, Christopher G. R. Wallis, Jennifer Y. H. Chan, Jason D. McEwen

Wavelets on the sphere have been developed to solve such problems for data defined on the sphere, which arise in numerous fields such as cosmology and geophysics.
